agent = Agent(
    model=Claude(
        id="claude-sonnet-4-6",

# Note: String syntax (model="azure-foundry-claude:claude-sonnet-4-5") works for basic usage.
# Use the class syntax above when configuring thinking or other model-specific parameters.

# ---------------------------------------------------------------------------
# Run Agent
# ---------------------------------------------------------------------------
if __name__ == "__main__":
    # --- Sync ---
    agent.print_response("Share a very scary 2 sentence horror story")

    # --- Sync + Streaming ---
    agent.print_response("Share a very scary 2 sentence horror story", stream=True)

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Install dependencies

uv pip install -U agno anthropic

Export environment variables

export ANTHROPIC_FOUNDRY_API_KEY="your_anthropic_foundry_api_key_here"
export ANTHROPIC_FOUNDRY_RESOURCE="your_anthropic_foundry_resource_here"

Select the Claude deployment

Deploy Claude Sonnet 4.6 in the resource named by ANTHROPIC_FOUNDRY_RESOURCE. This variable takes the resource name, not the full endpoint URL. Set ANTHROPIC_FOUNDRY_API_KEY to that resource's key.

The source assumes the deployment is named claude-sonnet-4-6. If you chose another name, replace the model's id with your deployment name while retaining the other model settings. See Claude deployment and inference setup.

Run the example

Save the code above as thinking.py, then run:

python thinking.py
