OpenAI is partnering with Baseten to let enterprise customers use their existing financial commitments to OpenAI to pay for open-source models.
Announced as part of the new OpenAI Marketplace, the integration is one of 32 initial partnerships and makes a range of Baseten-served open models available directly through OpenAI’s platform.
Customers can access the models through Codex for coding tasks and a new Responses API for broader applications. This gives companies the flexibility to choose between OpenAI’s proprietary models and open-source alternatives for different tasks, without managing separate contracts or billing.
