The addition of OpenAI's newest models to Model Garden lets businesses and developers access OpenAI models through Google Cloud's unified enterprise AI platform, alongside more than 200 first-party, third-party, and open models.

With this update, developers can build with these models through APIs and connect their local Codex CLI and Desktop workflows directly to the Gemini platform for inference.
