Baseten partners with OpenAI to let OpenAI enterprise customers use existing commitments for open models served by Baseten within Codex or via the Responses API (Dannie Herzberg/Baseten)

Baseten’s partnership with OpenAI gives enterprise customers a way to use existing OpenAI commitments to access open models served by Baseten through Codex or the Responses API, reducing friction for organizations that want to mix proprietary and open model usage. Strategically, this lowers procurement and integration barriers while expanding AI architecture options, which could accelerate enterprise adoption and give IT teams more flexibility in model selection, governance, and cost management.
