OpenAI plans to release its next big AI model by December / The startup’s next flagship model, codenamed Orion, is slated to arrive around the two-year anniversary of ChatGPT.

OpenAI plans to launch Orion, its next frontier model, by December, The Verge has learned.

Unlike the release of OpenAI’s last two models, GPT-4o and o1, Orion won’t initially be released widely through ChatGPT. Instead, OpenAI is planning to grant access first to companies it works closely with in order for them to build their own products and features, according to a source familiar with the plan.

Another source tells The Verge that engineers inside Microsoft — OpenAI’s main partner for deploying AI models — are preparing to host Orion on Azure as early as November. While Orion is seen inside OpenAI as the successor to GPT-4, it’s unclear if the company will call it GPT-5 externally. As always, the release plan is subject to change and could slip. Microsoft declined to comment for this story, and OpenAI initially declined.

After CEO Sam Altman called this story “fake news,” OpenAI spokesperson Niko Felix told The Verge that the company doesn’t “have plans to release a model code-named Orion this year” but that “we do plan to release a lot of other great technology.”
