What this modality supports

  • Streaming
  • Tool calling
  • Structured outputs
  • Prompt caching

Frontier and open-weight language models behind an OpenAI-compatible endpoint. Streaming, tool calling, structured outputs, and vision pass straight through — and prompt caching is billed at the provider's cached rate, so the discount compounds.
