Baseten says it is one of the first open-model inference providers in the OpenAI B2B Marketplace, with a native Codex integration and Responses API path. OpenAI enterprise customers can use existing OpenAI commitments for Baseten-hosted open models such as Kimi K3, GLM-5.3, and DeepSeek V4.1 Flash, without a separate supplier contract; Baseten runs inference and Codex stays the developer interface.
