A former OpenAI researcher has issued a stark warning about the growing threat Google poses to OpenAI’s business, saying the tech giant’s Gemini AI models could potentially “kill” both OpenAI’s API business and its consumer subscriptions if Google pulls ahead in performance or decides to offer its AI for free.

The warning comes amid reports that OpenAI went into “Code Red” mode internally after Google launched Gemini 3.0, its latest and most capable AI model yet. According to people familiar with the matter, OpenAI CEO Sam Altman told employees that improving ChatGPT must become the company’s top priority, even as competitive pressure from Google intensifies.

In comments to Fortune, the former OpenAI researcher said the situation is unusually serious — and notably, one that Altman has been open about inside the company. “It’s pretty remarkable that Sam is so transparent about it,” the researcher said, adding that this is one of the rare moments where leadership has openly acknowledged the scale of the threat from Google.

The biggest concern, according to the researcher, is what happens if Google overtakes OpenAI in raw AI performance. OpenAI’s API business, which allows developers and companies to build products using its models, is a major revenue driver. If Google’s Gemini becomes clearly better — and cheaper — developers could quickly switch. “If Google overtakes OpenAI in performance, it’s basically going to kill OpenAI’s API business,” the researcher warned.
