February 16, 2026
OpenAI offered the API a “here’s the same version we run on ChatGPT” for experimentation. Only that copy of what ChatGPT was running was shut down.
gpt-4o-2024-08-06, the version that can be fine-tuned, has no deprecation announcement and no hint that it would go away, except the ChatGPT evidence that OpenAI doesn’t like offering delusion-causing AI models as their own product very much.
