According to internal sources, GPT-5.1 is already on Microsoft’s Azure servers. This means it will reach the public in just a few weeks.
OpenAI is going to release three versions: GPT-5.1 (base), GPT-5.1 (Reasoning), and GPT-5.1 Profor the most expensive subscription.
This has been confirmed by their internal contacts on the website. Bleeping Computerand you have also revealed the main new features of the new language model from Sam Altman’s company.
GPT-5.1: news and release date
OpenAI usually releases a new version of GPT every three or four months. GPT-5 was launched on August 7, so GPT-5.1 should be released in November or Decemberwhich fits with the “in the coming weeks” deadline of the leak.
As expected, due to the numbering, there will be no revolutionary new features in GPT-5.1. But if there is Major improvements to performance, guardrails, and programming module.
The current GPT-5 model has two tools to generate code: GPT-5-Codex-High y GPT-5-Codex-Mini. The Mini version consumes fewer resources, and its results in the benchmarks are very close: 74.5% compared to 71.3% for the Mini version.
OpenAI asks developers to use Mini for undemanding tasks. And to encourage its use, it has higher limits, that is, it allows it to be used longer than High.
According to this leak, GPT 5.1 will come with an even more powerful Codex-Mini model. Actually, all code generation has been boosted, it’s going to be the highlight of this release.
There will also be an overall performance increase across GPT-5.1not only in this aspect.
Better mental health protections
Finally, ChatGPT-5.1 offer stronger guardrails in everything that has to do with health. It will better detect when the user is depressed or has suicidal ideas. OpenAI is in trouble with this issue, with several lawsuits pending of people and minors who have committed suicide, “encouraged” by ChatGPT.
Artificial intelligence is designed to hook you, like social networks, but instead of resorting to “like” they resort to agreeing with you in everything, to become a false friend. And that is a problem for people with mental problems.
If we pay attention to this leak, GPT-5.1 (Base), GPT-5.1 (Reasoning), and GPT-5.1 Pro will be available in late Novemberor early December.
