OpenAI uses a "special version" of ChatGPT to track down internal information leaks. That's according to a report from The Information, citing a person familiar with the matter. When a news article about internal operations surfaces, OpenAI's security team feeds the text into this custom ChatGPT version, which has access to internal documents as well as employees' Slack and email messages.

The system then suggests possible sources of the leak by identifying files or communication channels that contain the published information and showing who had access to them. It's unclear whether OpenAI has actually caught anyone using this method.

What exactly makes this version special isn't known, but there's a clue: OpenAI engineers recently presented the architecture of an internal AI agent that could serve this purpose. It's designed to let employees run complex data analysis using natural language and has access to institutional knowledge stored in Slack messages, Google Docs, and more.

OpenAI released an update for GPT-5.2 Instant in ChatGPT and the API on February 10, 2026. The company says the update improves response style and quality, with more measured, contextually appropriate tone and clearer answers to advice and how-to questions that place the most important information up front. CEO Sam Altman addressed the scope of the changes: "Not a huge change, but hopefully you find it a little better."

The update targets the "Instant" variant, the model without reasoning steps. In the API, developers can access it via "gpt-5.2-chat-latest". In ChatGPT, users need to switch to "Instant" in the model picker. The model also kicks in automatically when GPT-5's router determines a reasoning model isn't necessary, or when users have run out of credits for heavier models, something that happens especially often on the free tier.
