langchain has had a model profile attribute since ~november! cool to see this pattern getting attention

every chat model auto-loads capabilities at init: context window, tool calling, structured output, modalities, reasoning.

works across Anthropic, OpenAI, Google, Bedrock, etc. thanks to data powered by the open-source  project.

we use the data for auto-configuring agents, summarization middleware, input gating, and more.
