Quick Start

Basic Usage

from strands_clova import ClovaModel
from strands import Agent

# Initialize CLOVA model
model = ClovaModel(
    api_key="your-clova-api-key",  # or set CLOVA_API_KEY env var
    model="HCX-005",
    temperature=0.7,
    max_tokens=2048
)

# Create an agent
agent = Agent(model=model)

# Use the agent
response = await agent.invoke_async("안녕하세요! 오늘 날씨가 어떤가요?")
print(response.message)

Streaming Responses

import asyncio
from strands_clova import ClovaModel

async def stream_example():
    model = ClovaModel(api_key="your-api-key")
    
    async for event in model.stream("한국의 전통 음식 3가지를 소개해주세요"):
        if event.get("type") == "text":
            print(event["text"], end="", flush=True)

asyncio.run(stream_example())

With System Prompt

model = ClovaModel(api_key="your-api-key")

async for event in model.stream(
    "Python 리스트 컴프리헨션을 설명해주세요",
    system_prompt="You are a helpful coding assistant. Provide concise answers."
):
    # Process streaming events
    pass

Configuration

Environment Variables

export CLOVA_API_KEY="your-api-key"
export CLOVA_REQUEST_ID="optional-request-id"  # For request tracking

Model Parameters

model = ClovaModel(
    model="HCX-005",        # Model ID (currently only HCX-005 is supported)
    temperature=0.7,        # Sampling temperature (0.0-1.0)
    max_tokens=4096,        # Maximum tokens to generate
    top_p=0.8,             # Nucleus sampling parameter
    top_k=0,               # Top-k sampling parameter
    repeat_penalty=1.1,     # Repetition penalty
    stop=["\\n\\n"],        # Stop sequences
)

Dynamic Configuration

# Update configuration at runtime
model.update_config(
    temperature=0.2,
    max_tokens=1024
)

# Get current configuration
config = model.get_config()
print(config)
