Cloud Changelog
November 3, 2026 · Together AI
Anthropic Messages API and OpenAI Responses API supported on Together AI
Together AI now supports the Anthropic Messages API at POST /v1/messages and the OpenAI Responses API at POST /v1/responses. To run an app built on either API on Together, change its API key, base URL, and model. Both APIs support zai-org/GLM-5.3 and zai-org/GLM-5.2 on serverless inference, and zai-org/GLM-5.3-Flash and zai-org/GLM-5.2 on dedicated model inference.
