+## Model profiles
+
+Model profiles are generated using the `langchain-profiles` CLI in `libs/model-profiles`. The `--data-dir` must point to the directory containing `profile_augmentations.toml`, not the top-level package directory.
+
+```bash
+# Run from libs/model-profiles
+cd libs/model-profiles
+
+# Refresh profiles for a partner in this repo
+uv run langchain-profiles refresh --provider openai --data-dir ../partners/openai/langchain_openai/data

+echo y | uv run langchain-profiles refresh --provider google --data-dir /path/to/langchain-google/libs/genai/langchain_google_genai/data
+```
+
+Example partners with profiles in this repo:
+
+- `libs/partners/openai/langchain_openai/data/` (provider: `openai`)
+- `libs/partners/anthropic/langchain_anthropic/data/` (provider: `anthropic`)
+- `libs/partners/perplexity/langchain_perplexity/data/` (provider: `perplexity`)
+
+The `echo y |` pipe is required when `--data-dir` is outside the `libs/model-profiles` working directory.
