# Announcing our partnership with OpenAI

## Retrieval answer

Thesis: This partnership makes open-model inference a more directly accessible option within existing OpenAI enterprise workflows, rather than requiring customers to arrange a separate provider relationship.

Thesis: This partnership makes open-model inference a more directly accessible option within existing OpenAI enterprise workflows, rather than requiring customers to arrange a separate provider relationship.

Observed facts: Baseten says it is one of the first open-model inference providers in OpenAI’s B2B Marketplace. The company says enterprise customers can use existing OpenAI commitments for its open models in Codex or through the Responses API. Baseten says native Codex access is available through a waitlist. These are claims and details in Baseten’s own announcement.

Mechanism: The integration joins model delivery to an existing enterprise access and commitment path. That could reduce procurement and workflow friction for teams that want to route coding tasks across open and closed models. Why now: Baseten frames agentic coding as a widely adopted use case and argues that models’ relative cost, quality, latency, and capacity advantages change quickly, making multi-model routing useful.

Implication: The announcement creates a plausible path for enterprises to test or deploy open models alongside OpenAI models without treating provider selection as a wholly separate workflow. It does not establish that the integration will produce lower total costs or better coding outcomes. Evidence boundary: The source is Baseten’s announcement; it provides no independent performance comparison, named model roster, prices, regional availability, or detailed rollout timeline.

Watch condition: Look for the Codex waitlist opening into general availability, plus published model, pricing, and availability details. Those would show whether the announced access path becomes a practical production option rather than remaining a partnership offer.
