- When
-gis used with registered plugin EPs but none of the selected EPs is an NVIDIA GPU,ext_stream_remains empty, yet this passes its address.AppendPluginExecutionProvidersthen callsGetHandle(), andSyncStream_GetHandledereferences the null underlyingOrtSyncStream, causing a crash. Pass the pointer only when stream creation succeeded.
onnxruntime/test/perftest/ort_test_session.cc:125 - This chooses the first NVIDIA GPU device in the entire environment, not the device(s) selected later by
--select_ep_devices/--filter_ep_devices. On a multi-GPU EP, selecting GPU 1 can therefore create a GPU 0 stream and pass it to the GPU 1 EP instance (and multiple NVIDIA plugin EPs can receive a stream owned by a different EP), leading to invalid cross-device/EP stream usage. Create streams from the exact selectedOrtEpDeviceset and either maintain one per EP/device or reject unsupported multi-device combinations.

devang-ml Scott McKay (@skottmckay) is there any compatibility guidance or process from the ORT team as it relates to deprecation / removal of in-tree EPs? The NVIDIA folks want to remove their provider bridge EP code, and I wanted to double-check if there's any lifecycle process to follow (e.g., any broad comms that need to go out to community mailing lists, doc updates, etc.) or if it's ok to just remove the code. |

Overall this is a clean removal of the legacy provider-bridge NvTensorRTRTXExecutionProvider and nice addition of autoep graphics interop tests.
A few follow-up items noted inline (for plugin EP -g I/O binding in onnxruntime_perf_test, Python InferenceSession provider fallback/validation when NvTensorRTRTXExecutionProvider is registered as a plugin EP, and unused vulkan_headers in cmake/deps.txt), plus one cleanup in an untouched header:
- In
onnxruntime/core/providers/cuda/shared_inc/cuda_call.h(lines 19 and 30),CU_CALLandCU_CALL_THROWwere added in #26948 for the legacy NV EP and relied on theCudaErrString<CUresult>specialization andCudaCall<CUresult, ...>explicit template instantiations in the deletedonnxruntime/core/providers/nv_tensorrt_rtx/nv_cuda_call.cc. Neitheronnxruntime/core/providers/cuda/cuda_call.ccnoronnxruntime/core/providers/tensorrt/cuda_call.ccinstantiatesCudaCall<CUresult, ...>, leaving those macros without a backing definition.
- perftest: keep run-end synchronization for plugin EP IO binding, skip unused outputs_ pre-allocation, and bind string outputs to host memory. - python: restore TensorRT/NvTensorRTRTX mutual-exclusion check and CUDA fallback handling for the plugin EP. - Remove unused vulkan_headers dependency and CU_CALL/CU_CALL_THROW macros that lost their backing definitions.

…for removed EP name, and restore NV RTX test exclusions

Thanks for the update. Following two issues might need to address as well.

Chi Lo (@chilo-ms) Addressed the 2nd issue in latest commit, thank you. For the first issue, The missing completion barrier is in the WebGPU EP and doesn't depend on -g. The plugin -g path intentionally does not set disable_synchronize_execution_providers, so Run() still calls OnRunEnd(sync_stream=true) and stream cleanup with sync, exactly as the non--g path does. SynchronizeOutputs() is an extra wait on top, through OrtEp::Sync when the EP implements it. WebGPU skips both: OnRunEnd ignores sync_stream and only flushes, its sync stream's OnSessionRunEnd is a no-op, and it doesn't implement OrtEp::Sync. So WebGPU timings stop at submission whether or not -g is used. The NV TensorRT RTX plugin EP doesn't implement OrtEp::Sync but synchronizes its stream at run end when sync_stream is set, so timings include device execution with or without -g. The fix belongs in the WebGPU EP: honour sync_stream in OnRunEnd (e.g. via FlushAndWaitChecked), and/or implement OrtEp::Sync |

Thanks for the cleanup. The removal is thorough: at this head git grep for the removed symbols only finds the intentional leftovers (the NvTensorRtRtxProviderOptions typedef, kNvTensorRTRTXExecutionProvider, and the DQ → MatMulNBits EP-name check), the branch merges cleanly with current main, and the earlier review threads are addressed.
One item to fix before merge: Android CI / AndroidBinarySizeCheckJob_MinimalBaseline is the only failing check, and it is caused by the new deprecation branch in provider_registration.cc (numbers and a suggested fix inline). Compiling that branch out of minimal builds, together with its test, should turn it green and makes this PR a net size reduction for that build.
On the WebGPU -g timing discussion above (not a new finding): I agree the fix belongs in the WebGPU EP (honour sync_stream in OnRunEnd and/or implement OrtEp::Sync) and don't see it as a blocker for this PR. One nuance for that thread: without -g, the output copy to the host (BufferManager::Download, which blocks on MapAsync) is already an implicit completion barrier, so it is the -g IO-binding path that removes it. Until the WebGPU change lands, -g timings for that EP are submit-only, so it is worth tracking as a follow-up.

These notes cover changes since ONNX Runtime 1.31.1. CUDA and WebGPU kernel updates are summarized here; detailed provider notes are covered by their separate plugin EP releases. ## Highlights - Reintegrated **ONNX 1.23.2** with **opset 28** operator support (`SpaceToDepth`, `Mod`, signed `BitShift`, and `BFloat16` extensions) and updated **DLPack to v1.3** across all implemented ORT numeric and boolean tensor types ([#33134](microsoft/onnxruntime#33134), [#32362](microsoft/onnxruntime#32362), [#33848](microsoft/onnxruntime#33848)). - Added a session-scoped **CPU/GPU hybrid MoE offload** planner and execution backend for quantized `QMoE` (NVFP4, INT4, INT3, and INT2) and block-packed `MoEPacked` models, backed by shared-layout AVX-512/AVX2 CPU `QMoE` kernels and memory-mapped expert storage ([#33450](microsoft/onnxruntime#33450), [#33451](microsoft/onnxruntime#33451), [#33452](microsoft/onnxruntime#33452), [#33973](microsoft/onnxruntime#33973)). - Expanded core APIs with `OrtApi::EpDevice_GetMemoryCapacity`, explicit multi-mode weightless compilation (`ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode`), Python bindings for the Model Package APIs, and zero-copy CPU buffer borrowing in `AddExternalInitializers` ([#33447](microsoft/onnxruntime#33447), [#32899](microsoft/onnxruntime#32899), [#33640](microsoft/onnxruntime#33640), [#33877](microsoft/onnxruntime#33877)). - Eliminated superlinear bottlenecks in allocation planning, constant sharing, graph I/O mapping, and topological sorting—reducing session initialization on 100k-node constant-heavy graphs from minutes to seconds—and added pipelined pinned-memory staging for external GPU weight loading ([#33407](microsoft/onnxruntime#33407), [#33939](microsoft/onnxruntime#33939), [#34009](microsoft/onnxruntime#34009), [#33839](microsoft/onnxruntime#33839)). - Expanded shared generative AI and quantized contrib operators, including Kimi Delta Attention (`GatedDeltaNet` per-key-dimension decay), right-padded chunked prefill in `GroupQueryAttention`, native GGUF/block-packed operators (`GatherPacked`, `MatMulPacked`, `MoEPacked`), and sparse-attention index sharing ([#33817](microsoft/onnxruntime#33817), [#33503](microsoft/onnxruntime#33503), [#33953](microsoft/onnxruntime#33953), [#33224](microsoft/onnxruntime#33224)). ## Announcements & Compatibility - **CUDA Plugin EP v0.4.0** and **WebGPU Plugin EP v0.6.0** are matched with ONNX Runtime 1.32.0 ([#33214](microsoft/onnxruntime#33214)). For **contrib-op compatibility**, core and the plugin must use the same contributed-operator schemas; building both from the **same ONNX Runtime revision** is recommended. Schema mismatches can cause incorrect execution or crashes and may not be detected during plugin registration. - **ACL EP removed:** Following its deprecation in 1.31.0, the Arm Compute Library (`ACLExecutionProvider`) execution provider, its build options, and its standalone C registration API have been removed. Python's `get_all_providers()` no longer lists `ACLExecutionProvider`; applications should remove it from explicit provider lists ([#33851](microsoft/onnxruntime#33851)). - **Legacy provider-bridge `NvTensorRTRTXExecutionProvider` removed:** In-tree provider-bridge `NvTensorRTRTXExecutionProvider` sources have been removed in favor of the standalone NVIDIA TensorRT RTX plugin EP registered via `OrtApi::RegisterExecutionProviderLibrary`. `NvTensorRtRtxProviderOptions` is retained as a deprecated declaration for source compatibility, and legacy `AppendExecutionProvider` calls now report a deprecation error directing callers to the plugin EP ([#32276](microsoft/onnxruntime#32276)). - **ONNX 1.23.2 integration:** ONNX has been upgraded to **1.23.2**, raising supported opset ceilings to **28** and restoring `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E2M3` and `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E3M2` public element-type mappings and `Cast` conversions ([#33134](microsoft/onnxruntime#33134)). - **DLPack v1.3 boolean contract change:** DLPack has been upgraded to **v1.3** with native `kDLBool` metadata and bidirectional support for all implemented ORT numeric and boolean types, including all five `float8` formats, packed `float4`, `int4`/`uint4`, and `int2`/`uint2` (`float6` remains unsupported in DLPack). The low-level `is_bool_tensor` override was removed, and `uint8` DLPack metadata now always imports as `uint8` ([#33848](microsoft/onnxruntime#33848)). - **Weightless compilation API migration:** `OrtCompileApi::ModelCompilationOptions_SetWeightlessEnabled` and the `ep.enable_weightless` / `ep.enable_weightless_ep_context_nodes` session options are deprecated in favor of `ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode` (`"0"` = `NONE`, `"1"` = `EXTERNAL_ONLY`, `"2"` = `ALL`). EPs can now advertise multi-mode capability via `OrtWeightlessSupport_ALL_OR_EXTERNAL_ONLY` and `weightless_supported_modes` ([#32899](microsoft/onnxruntime#32899)). - **Training CI retirement:** Training build and test lanes were retired from active GitHub Actions CI workflows while retaining inference build coverage ([#33836](microsoft/onnxruntime#33836)). - This is the last release for [CocoaPods](https://cocoapods.org/), and we will switch to [Swift Package Manager](https://docs.swift.org/latest/documentation/packagemanagerdocs/). - We will use combo onnxruntime-gpu python package to reduce storage size from next release. You can test it [here](https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/ORT-Nightly/PyPI/onnxruntime-gpu/overview) ## New Features ### Core APIs & Runtime - Added `OrtApi::EpDevice_GetMemoryCapacity` (C++ `EpDevice::GetMemoryCapacity()`) and `OrtEpFactory::GetDeviceMemoryCapacity` to query device-global total memory and estimated currently available memory (`DEFAULT` or `HOST_ACCESSIBLE`), with built-in and plugin CUDA EP support ([#33447](microsoft/onnxruntime#33447)). - Expanded the app–EP weightless contract so EPs advertise all supported weightless modes (`weightless_supported_modes`), applications request an explicit mode (`ModelCompilationOptions_SetWeightlessMode` / `ep.enable_weightless_mode`), and compiled EPContext models record `weightless_mode` and `external_dependencies` (`source_model`, `external_weights`, `ep_context_binary`) in model metadata ([#32899](microsoft/onnxruntime#32899)). - Extended `session.use_external_initializer_file_buffers_directly="1"` to `AddExternalInitializers` for zero-copy borrowing of naturally aligned CPU buffers larger than 127 bytes on little-endian hosts, and documented the read-only guarantee for external initializers added via `OrtModelEditorApi::AddInitializerToGraph` with `data_is_external=true` ([#33877](microsoft/onnxruntime#33877), [#33717](microsoft/onnxruntime#33717)). - Added lock-free multi-worker pinned-memory staging (`session.external_data_loader.*`) to accelerate external initializer loading into GPU memory across built-in and plugin CUDA EPs ([#33839](microsoft/onnxruntime#33839)). - Added a session-scoped MoE/QMoE CPU/GPU offload planner and memory-budget ledger (`session.moe.offload.*`), generic `session.kernel_dispatch_policy` (`auto`, `latency`, `memory`, `safe`) configuration plumbing, Level-1 workspace/prepack memory accounting fallback for nodes absent from memory-profile CSVs, and internal capability-planning protocol types ([#33451](microsoft/onnxruntime#33451), [#33042](microsoft/onnxruntime#33042), [#33311](microsoft/onnxruntime#33311), [#33841](microsoft/onnxruntime#33841)). - Enabled cross-thread reuse of idle device streams when graph capture is disabled and providers register device-selection callbacks, and enabled compile-session profiling (`<profile_file>_compile`) in `onnxruntime_perf_test` when `-p` is used with `--compile_ep_context` ([#33053](microsoft/onnxruntime#33053), [#33694](microsoft/onnxruntime#33694)). - Made `onnxruntime_DISABLE_EXCEPTIONS` (`--disable_exceptions`) usable without `onnxruntime_MINIMAL_BUILD` and added the `onnxruntime_DISABLE_STREAM=ON` CMake option to disable device-stream support in non-minimal builds ([#33120](microsoft/onnxruntime#33120), [#33482](microsoft/onnxruntime#33482)). ### ONNX Opset 28 & Shared Contrib Operators These updates affect core ONNX and contributed operator schemas and cross-provider behavior, not only the separately released GPU plugins. - Added ONNX opset 28 operator support: native `SpaceToDepth` (`DCR` and `CRD`) on CPU and CUDA with version-split registrations across DML, JS, WebGPU, and QNN; opset-28 floating floor-modulus `Mod` on CPU, CUDA, and DML; opset-28 `BFloat16` support for `Compress`, `OneHot`, `ReverseSequence`, `Unique`, `Celu`, and `Einsum` on CPU (plus `Compress`, `OneHot`, and `ReverseSequence` on CUDA); and `BFloat16` `Pad` (opsets 21–25) on CPU and CUDA ([#32362](microsoft/onnxruntime#32362), [#32369](microsoft/onnxruntime#32369), [#32378](microsoft/onnxruntime#32378), [#34062](microsoft/onnxruntime#34062)). - Extended `GatedDeltaNet` with Kimi Delta Attention (KDA) per-key-dimension decay across CPU, CUDA, and WebGPU, and extended `GatedDeltaNet` and `CausalConvWithState` state/gate handling for multi-token speculative decoding ([#33817](microsoft/onnxruntime#33817), [#33471](microsoft/onnxruntime#33471)). - Added an optional `query_seqlens` input to `GroupQueryAttention` to skip right-padded prefill tokens and idle batch entries (`query_seqlens[b] = 0`) on CPU and CUDA, and added `q_norm_epsilon` / `k_norm_epsilon` attributes to preserve distinct Q and K normalization epsilons during GQA pre-norm fusion ([#33503](microsoft/onnxruntime#33503), [#33505](microsoft/onnxruntime#33505), [#33832](microsoft/onnxruntime#33832), [#33363](microsoft/onnxruntime#33363)). - Defined the INT3 `QMoE` v1 packed-code contract, added opt-in post-SiLU clipping (`swiglu_limit_after_activation`) and tanh-`GEGLU` (`activation_type="geglu"`) support to MoE/QMoE schemas, and added `GatherPacked` (CPU/CUDA), `MatMulPacked` (CUDA, including native Bolt `global_scale`), and `MoEPacked` (CUDA) to consume native GGUF/block-packed quantized weights directly ([#33394](microsoft/onnxruntime#33394), [#33954](microsoft/onnxruntime#33954), [#33633](microsoft/onnxruntime#33633), [#33953](microsoft/onnxruntime#33953), [#33962](microsoft/onnxruntime#33962)). - Added `PackedSparseAttentionIndexerMerge` for multi-token prediction index sharing and optional `state_status` / mid-state outputs on `PackedSparseAttentionIndexer` across CUDA and WebGPU; extended `GatedAdd` with an optional projected `gate_weight` across CPU, CUDA, and WebGPU; and supported empty unpacked weights in CPU and WebGPU `MatMulNBits` ([#33224](microsoft/onnxruntime#33224), [#33383](microsoft/onnxruntime#33383), [#33472](microsoft/onnxruntime#33472), [#33470](microsoft/onnxruntime#33470), [#33559](microsoft/onnxruntime#33559)). - Registered core contrib schemas for provider-targeted LLM and speculative-decoding operators, including `SwiGLU`, `RMSNormRotary`, `HyperConnectionLowRankMix`, `RouterGateUpProj`, `SpeculativePrefixCommit`, `GatedDeltaNetStateReplay`, `ConvStateReplay`, and `MatMulNBitsQLoRA` ([#32126](microsoft/onnxruntime#32126), [#33469](microsoft/onnxruntime#33469), [#33384](microsoft/onnxruntime#33384), [#33650](microsoft/onnxruntime#33650), [#33474](microsoft/onnxruntime#33474), [#33213](microsoft/onnxruntime#33213), [#33493](microsoft/onnxruntime#33493), [#33370](microsoft/onnxruntime#33370)). ### Plugin Execution Provider Infrastructure - Fixed an `OrtMemoryInfo` ABI mismatch across the ORT/plugin EP boundary by converting `OrtMemoryInfo` instances exclusively through the C API ([#33571](microsoft/onnxruntime#33571)). - Zero-initialized `OrtEpFactory` structs in provider-bridge EP factories so unimplemented optional callbacks are null, and prevented double DLL initialization and handle leaks when probing and registering plugin EP libraries ([#33117](microsoft/onnxruntime#33117), [#33701](microsoft/onnxruntime#33701)). - Hardened portable model-package EP recreation, custom-domain preservation, UTF-8 path handling, and `shared_assets` path confinement and symlink validation ([#32790](microsoft/onnxruntime#32790), [#33826](microsoft/onnxruntime#33826)). ... (truncated) Commits viewable in [compare view](microsoft/onnxruntime@v1.31.1...v1.32.0). </details> Updated [Microsoft.ML.OnnxRuntime.Managed](https://github.com/microsoft/onnxruntime) from 1.31.1 to 1.32.0. <details> <summary>Release notes</summary> _Sourced from [Microsoft.ML.OnnxRuntime.Managed's releases](https://github.com/microsoft/onnxruntime/releases)._ ## 1.32.0 ONNX Runtime 1.32.0 reintegrates ONNX 1.23.2 with opset 28 support, introduces CPU/GPU hybrid MoE offloading and shared-layout CPU QMoE kernels, expands device-memory, weightless-compilation, and Python model-package APIs, dramatically accelerates session initialization on large graphs, and strengthens runtime and optimizer reliability. These notes cover changes since ONNX Runtime 1.31.1. CUDA and WebGPU kernel updates are summarized here; detailed provider notes are covered by their separate plugin EP releases. ## Highlights - Reintegrated **ONNX 1.23.2** with **opset 28** operator support (`SpaceToDepth`, `Mod`, signed `BitShift`, and `BFloat16` extensions) and updated **DLPack to v1.3** across all implemented ORT numeric and boolean tensor types ([#33134](microsoft/onnxruntime#33134), [#32362](microsoft/onnxruntime#32362), [#33848](microsoft/onnxruntime#33848)). - Added a session-scoped **CPU/GPU hybrid MoE offload** planner and execution backend for quantized `QMoE` (NVFP4, INT4, INT3, and INT2) and block-packed `MoEPacked` models, backed by shared-layout AVX-512/AVX2 CPU `QMoE` kernels and memory-mapped expert storage ([#33450](microsoft/onnxruntime#33450), [#33451](microsoft/onnxruntime#33451), [#33452](microsoft/onnxruntime#33452), [#33973](microsoft/onnxruntime#33973)). - Expanded core APIs with `OrtApi::EpDevice_GetMemoryCapacity`, explicit multi-mode weightless compilation (`ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode`), Python bindings for the Model Package APIs, and zero-copy CPU buffer borrowing in `AddExternalInitializers` ([#33447](microsoft/onnxruntime#33447), [#32899](microsoft/onnxruntime#32899), [#33640](microsoft/onnxruntime#33640), [#33877](microsoft/onnxruntime#33877)). - Eliminated superlinear bottlenecks in allocation planning, constant sharing, graph I/O mapping, and topological sorting—reducing session initialization on 100k-node constant-heavy graphs from minutes to seconds—and added pipelined pinned-memory staging for external GPU weight loading ([#33407](microsoft/onnxruntime#33407), [#33939](microsoft/onnxruntime#33939), [#34009](microsoft/onnxruntime#34009), [#33839](microsoft/onnxruntime#33839)). - Expanded shared generative AI and quantized contrib operators, including Kimi Delta Attention (`GatedDeltaNet` per-key-dimension decay), right-padded chunked prefill in `GroupQueryAttention`, native GGUF/block-packed operators (`GatherPacked`, `MatMulPacked`, `MoEPacked`), and sparse-attention index sharing ([#33817](microsoft/onnxruntime#33817), [#33503](microsoft/onnxruntime#33503), [#33953](microsoft/onnxruntime#33953), [#33224](microsoft/onnxruntime#33224)). ## Announcements & Compatibility - **CUDA Plugin EP v0.4.0** and **WebGPU Plugin EP v0.6.0** are matched with ONNX Runtime 1.32.0 ([#33214](microsoft/onnxruntime#33214)). For **contrib-op compatibility**, core and the plugin must use the same contributed-operator schemas; building both from the **same ONNX Runtime revision** is recommended. Schema mismatches can cause incorrect execution or crashes and may not be detected during plugin registration. - **ACL EP removed:** Following its deprecation in 1.31.0, the Arm Compute Library (`ACLExecutionProvider`) execution provider, its build options, and its standalone C registration API have been removed. Python's `get_all_providers()` no longer lists `ACLExecutionProvider`; applications should remove it from explicit provider lists ([#33851](microsoft/onnxruntime#33851)). - **Legacy provider-bridge `NvTensorRTRTXExecutionProvider` removed:** In-tree provider-bridge `NvTensorRTRTXExecutionProvider` sources have been removed in favor of the standalone NVIDIA TensorRT RTX plugin EP registered via `OrtApi::RegisterExecutionProviderLibrary`. `NvTensorRtRtxProviderOptions` is retained as a deprecated declaration for source compatibility, and legacy `AppendExecutionProvider` calls now report a deprecation error directing callers to the plugin EP ([#32276](microsoft/onnxruntime#32276)). - **ONNX 1.23.2 integration:** ONNX has been upgraded to **1.23.2**, raising supported opset ceilings to **28** and restoring `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E2M3` and `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E3M2` public element-type mappings and `Cast` conversions ([#33134](microsoft/onnxruntime#33134)). - **DLPack v1.3 boolean contract change:** DLPack has been upgraded to **v1.3** with native `kDLBool` metadata and bidirectional support for all implemented ORT numeric and boolean types, including all five `float8` formats, packed `float4`, `int4`/`uint4`, and `int2`/`uint2` (`float6` remains unsupported in DLPack). The low-level `is_bool_tensor` override was removed, and `uint8` DLPack metadata now always imports as `uint8` ([#33848](microsoft/onnxruntime#33848)). - **Weightless compilation API migration:** `OrtCompileApi::ModelCompilationOptions_SetWeightlessEnabled` and the `ep.enable_weightless` / `ep.enable_weightless_ep_context_nodes` session options are deprecated in favor of `ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode` (`"0"` = `NONE`, `"1"` = `EXTERNAL_ONLY`, `"2"` = `ALL`). EPs can now advertise multi-mode capability via `OrtWeightlessSupport_ALL_OR_EXTERNAL_ONLY` and `weightless_supported_modes` ([#32899](microsoft/onnxruntime#32899)). - **Training CI retirement:** Training build and test lanes were retired from active GitHub Actions CI workflows while retaining inference build coverage ([#33836](microsoft/onnxruntime#33836)). - This is the last release for [CocoaPods](https://cocoapods.org/), and we will switch to [Swift Package Manager](https://docs.swift.org/latest/documentation/packagemanagerdocs/). - We will use combo onnxruntime-gpu python package to reduce storage size from next release. You can test it [here](https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/ORT-Nightly/PyPI/onnxruntime-gpu/overview) ## New Features ### Core APIs & Runtime - Added `OrtApi::EpDevice_GetMemoryCapacity` (C++ `EpDevice::GetMemoryCapacity()`) and `OrtEpFactory::GetDeviceMemoryCapacity` to query device-global total memory and estimated currently available memory (`DEFAULT` or `HOST_ACCESSIBLE`), with built-in and plugin CUDA EP support ([#33447](microsoft/onnxruntime#33447)). - Expanded the app–EP weightless contract so EPs advertise all supported weightless modes (`weightless_supported_modes`), applications request an explicit mode (`ModelCompilationOptions_SetWeightlessMode` / `ep.enable_weightless_mode`), and compiled EPContext models record `weightless_mode` and `external_dependencies` (`source_model`, `external_weights`, `ep_context_binary`) in model metadata ([#32899](microsoft/onnxruntime#32899)). - Extended `session.use_external_initializer_file_buffers_directly="1"` to `AddExternalInitializers` for zero-copy borrowing of naturally aligned CPU buffers larger than 127 bytes on little-endian hosts, and documented the read-only guarantee for external initializers added via `OrtModelEditorApi::AddInitializerToGraph` with `data_is_external=true` ([#33877](microsoft/onnxruntime#33877), [#33717](microsoft/onnxruntime#33717)). - Added lock-free multi-worker pinned-memory staging (`session.external_data_loader.*`) to accelerate external initializer loading into GPU memory across built-in and plugin CUDA EPs ([#33839](microsoft/onnxruntime#33839)). - Added a session-scoped MoE/QMoE CPU/GPU offload planner and memory-budget ledger (`session.moe.offload.*`), generic `session.kernel_dispatch_policy` (`auto`, `latency`, `memory`, `safe`) configuration plumbing, Level-1 workspace/prepack memory accounting fallback for nodes absent from memory-profile CSVs, and internal capability-planning protocol types ([#33451](microsoft/onnxruntime#33451), [#33042](microsoft/onnxruntime#33042), [#33311](microsoft/onnxruntime#33311), [#33841](microsoft/onnxruntime#33841)). - Enabled cross-thread reuse of idle device streams when graph capture is disabled and providers register device-selection callbacks, and enabled compile-session profiling (`<profile_file>_compile`) in `onnxruntime_perf_test` when `-p` is used with `--compile_ep_context` ([#33053](microsoft/onnxruntime#33053), [#33694](microsoft/onnxruntime#33694)). - Made `onnxruntime_DISABLE_EXCEPTIONS` (`--disable_exceptions`) usable without `onnxruntime_MINIMAL_BUILD` and added the `onnxruntime_DISABLE_STREAM=ON` CMake option to disable device-stream support in non-minimal builds ([#33120](microsoft/onnxruntime#33120), [#33482](microsoft/onnxruntime#33482)). ### ONNX Opset 28 & Shared Contrib Operators These updates affect core ONNX and contributed operator schemas and cross-provider behavior, not only the separately released GPU plugins. - Added ONNX opset 28 operator support: native `SpaceToDepth` (`DCR` and `CRD`) on CPU and CUDA with version-split registrations across DML, JS, WebGPU, and QNN; opset-28 floating floor-modulus `Mod` on CPU, CUDA, and DML; opset-28 `BFloat16` support for `Compress`, `OneHot`, `ReverseSequence`, `Unique`, `Celu`, and `Einsum` on CPU (plus `Compress`, `OneHot`, and `ReverseSequence` on CUDA); and `BFloat16` `Pad` (opsets 21–25) on CPU and CUDA ([#32362](microsoft/onnxruntime#32362), [#32369](microsoft/onnxruntime#32369), [#32378](microsoft/onnxruntime#32378), [#34062](microsoft/onnxruntime#34062)). - Extended `GatedDeltaNet` with Kimi Delta Attention (KDA) per-key-dimension decay across CPU, CUDA, and WebGPU, and extended `GatedDeltaNet` and `CausalConvWithState` state/gate handling for multi-token speculative decoding ([#33817](microsoft/onnxruntime#33817), [#33471](microsoft/onnxruntime#33471)). - Added an optional `query_seqlens` input to `GroupQueryAttention` to skip right-padded prefill tokens and idle batch entries (`query_seqlens[b] = 0`) on CPU and CUDA, and added `q_norm_epsilon` / `k_norm_epsilon` attributes to preserve distinct Q and K normalization epsilons during GQA pre-norm fusion ([#33503](microsoft/onnxruntime#33503), [#33505](microsoft/onnxruntime#33505), [#33832](microsoft/onnxruntime#33832), [#33363](microsoft/onnxruntime#33363)). - Defined the INT3 `QMoE` v1 packed-code contract, added opt-in post-SiLU clipping (`swiglu_limit_after_activation`) and tanh-`GEGLU` (`activation_type="geglu"`) support to MoE/QMoE schemas, and added `GatherPacked` (CPU/CUDA), `MatMulPacked` (CUDA, including native Bolt `global_scale`), and `MoEPacked` (CUDA) to consume native GGUF/block-packed quantized weights directly ([#33394](microsoft/onnxruntime#33394), [#33954](microsoft/onnxruntime#33954), [#33633](microsoft/onnxruntime#33633), [#33953](microsoft/onnxruntime#33953), [#33962](microsoft/onnxruntime#33962)). - Added `PackedSparseAttentionIndexerMerge` for multi-token prediction index sharing and optional `state_status` / mid-state outputs on `PackedSparseAttentionIndexer` across CUDA and WebGPU; extended `GatedAdd` with an optional projected `gate_weight` across CPU, CUDA, and WebGPU; and supported empty unpacked weights in CPU and WebGPU `MatMulNBits` ([#33224](microsoft/onnxruntime#33224), [#33383](microsoft/onnxruntime#33383), [#33472](microsoft/onnxruntime#33472), [#33470](microsoft/onnxruntime#33470), [#33559](microsoft/onnxruntime#33559)). - Registered core contrib schemas for provider-targeted LLM and speculative-decoding operators, including `SwiGLU`, `RMSNormRotary`, `HyperConnectionLowRankMix`, `RouterGateUpProj`, `SpeculativePrefixCommit`, `GatedDeltaNetStateReplay`, `ConvStateReplay`, and `MatMulNBitsQLoRA` ([#32126](microsoft/onnxruntime#32126), [#33469](microsoft/onnxruntime#33469), [#33384](microsoft/onnxruntime#33384), [#33650](microsoft/onnxruntime#33650), [#33474](microsoft/onnxruntime#33474), [#33213](microsoft/onnxruntime#33213), [#33493](microsoft/onnxruntime#33493), [#33370](microsoft/onnxruntime#33370)). ### Plugin Execution Provider Infrastructure - Fixed an `OrtMemoryInfo` ABI mismatch across the ORT/plugin EP boundary by converting `OrtMemoryInfo` instances exclusively through the C API ([#33571](microsoft/onnxruntime#33571)). - Zero-initialized `OrtEpFactory` structs in provider-bridge EP factories so unimplemented optional callbacks are null, and prevented double DLL initialization and handle leaks when probing and registering plugin EP libraries ([#33117](microsoft/onnxruntime#33117), [#33701](microsoft/onnxruntime#33701)). - Hardened portable model-package EP recreation, custom-domain preservation, UTF-8 path handling, and `shared_assets` path confinement and symlink validation ([#32790](microsoft/onnxruntime#32790), [#33826](microsoft/onnxruntime#33826)). ...

The post-processor could consume a forged `executionComplete.json` written by another local user, and then run attacker-controlled output handling. Affected: `Microsoft.TestPlatform.CLI` 18.11.0 and earlier. Every version from 18.11.1 on is fixed, including 18.12.0. `Microsoft.TestPlatform.CLI` is the VSTest build that we ship into the .NET SDK.

CUDA and WebGPU kernel updates are summarized here; detailed provider notes are covered by their separate plugin EP releases. ## Highlights - Reintegrated **ONNX 1.23.2** with **opset 28** operator support (`SpaceToDepth`, `Mod`, signed `BitShift`, and `BFloat16` extensions) and updated **DLPack to v1.3** across all implemented ORT numeric and boolean tensor types ([#33134](microsoft/onnxruntime#33134), [#32362](microsoft/onnxruntime#32362), [#33848](microsoft/onnxruntime#33848)). - Added a session-scoped **CPU/GPU hybrid MoE offload** planner and execution backend for quantized `QMoE` (NVFP4, INT4, INT3, and INT2) and block-packed `MoEPacked` models, backed by shared-layout AVX-512/AVX2 CPU `QMoE` kernels and memory-mapped expert storage ([#33450](microsoft/onnxruntime#33450), [#33451](microsoft/onnxruntime#33451), [#33452](microsoft/onnxruntime#33452), [#33973](microsoft/onnxruntime#33973)). - Expanded core APIs with `OrtApi::EpDevice_GetMemoryCapacity`, explicit multi-mode weightless compilation (`ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode`), Python bindings for the Model Package APIs, and zero-copy CPU buffer borrowing in `AddExternalInitializers` ([#33447](microsoft/onnxruntime#33447), [#32899](microsoft/onnxruntime#32899), [#33640](microsoft/onnxruntime#33640), [#33877](microsoft/onnxruntime#33877)). - Eliminated superlinear bottlenecks in allocation planning, constant sharing, graph I/O mapping, and topological sorting—reducing session initialization on 100k-node constant-heavy graphs from minutes to seconds—and added pipelined pinned-memory staging for external GPU weight loading ([#33407](microsoft/onnxruntime#33407), [#33939](microsoft/onnxruntime#33939), [#34009](microsoft/onnxruntime#34009), [#33839](microsoft/onnxruntime#33839)). - Expanded shared generative AI and quantized contrib operators, including Kimi Delta Attention (`GatedDeltaNet` per-key-dimension decay), right-padded chunked prefill in `GroupQueryAttention`, native GGUF/block-packed operators (`GatherPacked`, `MatMulPacked`, `MoEPacked`), and sparse-attention index sharing ([#33817](microsoft/onnxruntime#33817), [#33503](microsoft/onnxruntime#33503), [#33953](microsoft/onnxruntime#33953), [#33224](microsoft/onnxruntime#33224)). ## Announcements & Compatibility - **CUDA Plugin EP v0.4.0** and **WebGPU Plugin EP v0.6.0** are matched with ONNX Runtime 1.32.0 ([#33214](microsoft/onnxruntime#33214)). For **contrib-op compatibility**, core and the plugin must use the same contributed-operator schemas; building both from the **same ONNX Runtime revision** is recommended. Schema mismatches can cause incorrect execution or crashes and may not be detected during plugin registration. - **ACL EP removed:** Following its deprecation in 1.31.0, the Arm Compute Library (`ACLExecutionProvider`) execution provider, its build options, and its standalone C registration API have been removed. Python's `get_all_providers()` no longer lists `ACLExecutionProvider`; applications should remove it from explicit provider lists ([#33851](microsoft/onnxruntime#33851)). - **Legacy provider-bridge `NvTensorRTRTXExecutionProvider` removed:** In-tree provider-bridge `NvTensorRTRTXExecutionProvider` sources have been removed in favor of the standalone NVIDIA TensorRT RTX plugin EP registered via `OrtApi::RegisterExecutionProviderLibrary`. `NvTensorRtRtxProviderOptions` is retained as a deprecated declaration for source compatibility, and legacy `AppendExecutionProvider` calls now report a deprecation error directing callers to the plugin EP ([#32276](microsoft/onnxruntime#32276)). - **ONNX 1.23.2 integration:** ONNX has been upgraded to **1.23.2**, raising supported opset ceilings to **28** and restoring `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E2M3` and `ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT6E3M2` public element-type mappings and `Cast` conversions ([#33134](microsoft/onnxruntime#33134)). - **DLPack v1.3 boolean contract change:** DLPack has been upgraded to **v1.3** with native `kDLBool` metadata and bidirectional support for all implemented ORT numeric and boolean types, including all five `float8` formats, packed `float4`, `int4`/`uint4`, and `int2`/`uint2` (`float6` remains unsupported in DLPack). The low-level `is_bool_tensor` override was removed, and `uint8` DLPack metadata now always imports as `uint8` ([#33848](microsoft/onnxruntime#33848)). - **Weightless compilation API migration:** `OrtCompileApi::ModelCompilationOptions_SetWeightlessEnabled` and the `ep.enable_weightless` / `ep.enable_weightless_ep_context_nodes` session options are deprecated in favor of `ModelCompilationOptions_SetWeightlessMode` and `ep.enable_weightless_mode` (`"0"` = `NONE`, `"1"` = `EXTERNAL_ONLY`, `"2"` = `ALL`). EPs can now advertise multi-mode capability via `OrtWeightlessSupport_ALL_OR_EXTERNAL_ONLY` and `weightless_supported_modes` ([#32899](microsoft/onnxruntime#32899)). - **Training CI retirement:** Training build and test lanes were retired from active GitHub Actions CI workflows while retaining inference build coverage ([#33836](microsoft/onnxruntime#33836)). - This is the last release for [CocoaPods](https://cocoapods.org/), and we will switch to [Swift Package Manager](https://docs.swift.org/latest/documentation/packagemanagerdocs/). - We will use combo onnxruntime-gpu python package to reduce storage size from next release. You can test it [here](https://aiinfra.visualstudio.com/PublicPackages/_artifacts/feed/ORT-Nightly/PyPI/onnxruntime-gpu/overview) ## New Features ### Core APIs & Runtime - Added `OrtApi::EpDevice_GetMemoryCapacity` (C++ `EpDevice::GetMemoryCapacity()`) and `OrtEpFactory::GetDeviceMemoryCapacity` to query device-global total memory and estimated currently available memory (`DEFAULT` or `HOST_ACCESSIBLE`), with built-in and plugin CUDA EP support ([#33447](microsoft/onnxruntime#33447)). - Expanded the app–EP weightless contract so EPs advertise all supported weightless modes (`weightless_supported_modes`), applications request an explicit mode (`ModelCompilationOptions_SetWeightlessMode` / `ep.enable_weightless_mode`), and compiled EPContext models record `weightless_mode` and `external_dependencies` (`source_model`, `external_weights`, `ep_context_binary`) in model metadata ([#32899](microsoft/onnxruntime#32899)). - Extended `session.use_external_initializer_file_buffers_directly="1"` to `AddExternalInitializers` for zero-copy borrowing of naturally aligned CPU buffers larger than 127 bytes on little-endian hosts, and documented the read-only guarantee for external initializers added via `OrtModelEditorApi::AddInitializerToGraph` with `data_is_external=true` ([#33877](microsoft/onnxruntime#33877), [#33717](microsoft/onnxruntime#33717)). - Added lock-free multi-worker pinned-memory staging (`session.external_data_loader.*`) to accelerate external initializer loading into GPU memory across built-in and plugin CUDA EPs ([#33839](microsoft/onnxruntime#33839)). - Added a session-scoped MoE/QMoE CPU/GPU offload planner and memory-budget ledger (`session.moe.offload.*`), generic `session.kernel_dispatch_policy` (`auto`, `latency`, `memory`, `safe`) configuration plumbing, Level-1 workspace/prepack memory accounting fallback for nodes absent from memory-profile CSVs, and internal capability-planning protocol types ([#33451](microsoft/onnxruntime#33451), [#33042](microsoft/onnxruntime#33042), [#33311](microsoft/onnxruntime#33311), [#33841](microsoft/onnxruntime#33841)). - Enabled cross-thread reuse of idle device streams when graph capture is disabled and providers register device-selection callbacks, and enabled compile-session profiling (`<profile_file>_compile`) in `onnxruntime_perf_test` when `-p` is used with `--compile_ep_context` ([#33053](microsoft/onnxruntime#33053), [#33694](microsoft/onnxruntime#33694)). - Made `onnxruntime_DISABLE_EXCEPTIONS` (`--disable_exceptions`) usable without `onnxruntime_MINIMAL_BUILD` and added the `onnxruntime_DISABLE_STREAM=ON` CMake option to disable device-stream support in non-minimal builds ([#33120](microsoft/onnxruntime#33120), [#33482](microsoft/onnxruntime#33482)). ### ONNX Opset 28 & Shared Contrib Operators These updates affect core ONNX and contributed operator schemas and cross-provider behavior, not only the separately released GPU plugins. - Added ONNX opset 28 operator support: native `SpaceToDepth` (`DCR` and `CRD`) on CPU and CUDA with version-split registrations across DML, JS, WebGPU, and QNN; opset-28 floating floor-modulus `Mod` on CPU, CUDA, and DML; opset-28 `BFloat16` support for `Compress`, `OneHot`, `ReverseSequence`, `Unique`, `Celu`, and `Einsum` on CPU (plus `Compress`, `OneHot`, and `ReverseSequence` on CUDA); and `BFloat16` `Pad` (opsets 21–25) on CPU and CUDA ([#32362](microsoft/onnxruntime#32362), [#32369](microsoft/onnxruntime#32369), [#32378](microsoft/onnxruntime#32378), [#34062](microsoft/onnxruntime#34062)). - Extended `GatedDeltaNet` with Kimi Delta Attention (KDA) per-key-dimension decay across CPU, CUDA, and WebGPU, and extended `GatedDeltaNet` and `CausalConvWithState` state/gate handling for multi-token speculative decoding ([#33817](microsoft/onnxruntime#33817), [#33471](microsoft/onnxruntime#33471)). - Added an optional `query_seqlens` input to `GroupQueryAttention` to skip right-padded prefill tokens and idle batch entries (`query_seqlens[b] = 0`) on CPU and CUDA, and added `q_norm_epsilon` / `k_norm_epsilon` attributes to preserve distinct Q and K normalization epsilons during GQA pre-norm fusion ([#33503](microsoft/onnxruntime#33503), [#33505](microsoft/onnxruntime#33505), [#33832](microsoft/onnxruntime#33832), [#33363](microsoft/onnxruntime#33363)). - Defined the INT3 `QMoE` v1 packed-code contract, added opt-in post-SiLU clipping (`swiglu_limit_after_activation`) and tanh-`GEGLU` (`activation_type="geglu"`) support to MoE/QMoE schemas, and added `GatherPacked` (CPU/CUDA), `MatMulPacked` (CUDA, including native Bolt `global_scale`), and `MoEPacked` (CUDA) to consume native GGUF/block-packed quantized weights directly ([#33394](microsoft/onnxruntime#33394), [#33954](microsoft/onnxruntime#33954), [#33633](microsoft/onnxruntime#33633), [#33953](microsoft/onnxruntime#33953), [#33962](microsoft/onnxruntime#33962)). - Added `PackedSparseAttentionIndexerMerge` for multi-token prediction index sharing and optional `state_status` / mid-state outputs on `PackedSparseAttentionIndexer` across CUDA and WebGPU; extended `GatedAdd` with an optional projected `gate_weight` across CPU, CUDA, and WebGPU; and supported empty unpacked weights in CPU and WebGPU `MatMulNBits` ([#33224](microsoft/onnxruntime#33224), [#33383](microsoft/onnxruntime#33383), [#33472](microsoft/onnxruntime#33472), [#33470](microsoft/onnxruntime#33470), [#33559](microsoft/onnxruntime#33559)). - Registered core contrib schemas for provider-targeted LLM and speculative-decoding operators, including `SwiGLU`, `RMSNormRotary`, `HyperConnectionLowRankMix`, `RouterGateUpProj`, `SpeculativePrefixCommit`, `GatedDeltaNetStateReplay`, `ConvStateReplay`, and `MatMulNBitsQLoRA` ([#32126](microsoft/onnxruntime#32126), [#33469](microsoft/onnxruntime#33469), [#33384](microsoft/onnxruntime#33384), [#33650](microsoft/onnxruntime#33650), [#33474](microsoft/onnxruntime#33474), [#33213](microsoft/onnxruntime#33213), [#33493](microsoft/onnxruntime#33493), [#33370](microsoft/onnxruntime#33370)). ### Plugin Execution Provider Infrastructure - Fixed an `OrtMemoryInfo` ABI mismatch across the ORT/plugin EP boundary by converting `OrtMemoryInfo` instances exclusively through the C API ([#33571](microsoft/onnxruntime#33571)). - Zero-initialized `OrtEpFactory` structs in provider-bridge EP factories so unimplemented optional callbacks are null, and prevented double DLL initialization and handle leaks when probing and registering plugin EP libraries ([#33117](microsoft/onnxruntime#33117), [#33701](microsoft/onnxruntime#33701)). - Hardened portable model-package EP recreation, custom-domain preservation, UTF-8 path handling, and `shared_assets` path confinement and symlink validation ([#32790](microsoft/onnxruntime#32790), [#33826](microsoft/onnxruntime#33826)). ...

The post-processor could consume a forged `executionComplete.json` written by another local user, and then run attacker-controlled output handling. Affected: `Microsoft.TestPlatform.CLI` 18.11.0 and earlier. Every version from 18.11.1 on is fixed, including 18.12.0. `Microsoft.TestPlatform.CLI` is the VSTest build that we ship into the .NET SDK. The recommended way to get this fix is to update your .NET SDK to the latest patched version, see the advisory for the SDK versions. The fix is also released in the `Microsoft.TestPlatform.CLI` package, for completeness. That package is rarely used directly. It is not a dependency of `Microsoft.NET.Test.Sdk` or `Microsoft.TestPlatform`, so those packages do not bring it in.
