10 Provider Variation

Script: example/10_provider_variation.py.

Provider variation keeps agent/session/tool code fixed and swaps only the Provider.

python example/10_provider_variation.py
python example/10_provider_variation.py anthropic

Path	Config
OpenAI-compatible	OPENAI_API_KEY, optional OPENAI_BASE_URL, OPENAI_DEFAULT_MODEL.
Anthropic	ANTHROPIC_API_KEY, Provider(provider_kind="anthropic", ...).
LiteLLM	Install openrath[litellm], then use Provider(provider_kind="litellm", model="provider/model").
Embedding	llm.embedding_provider plus EmbeddingProvider.
VLM	llm.vlm_provider plus VLMProvider.

Use this example as the starting point for documenting provider choice in application code.

The v1.2.2 script itself demonstrates OpenAI-compatible and Anthropic paths. LiteLLM uses the same Provider/chat_client_for registry boundary but requires the optional extra.
