B.AI Responses API Upgraded for Full Compatibility with Standard Protocols

On September 24, B.AI announced a major upgrade to its Responses API, enabling full compatibility with upstream standard protocols. Models on the platform can now be accessed via the /v1/responses endpoint, and new models from integrated providers will be automatically supported in the Codex client without additional configuration. The update adds support for MiMo, Qwen, and Hunyuan models to the official API, while the Mix and OL Station services now offer OpenAI, Gemini, and Grok models at a 40% discount.
