GPT-5.6 Pro Leaks Expose a Massive Jump in AI Reasoning Power
TL;DR
Geeky Gadgets reports a leak about GPT-5.6 Pro, allegedly scheduled for June 25, 2026. The article does not read like official confirmation and points to World of AI as the source. The main claim is a reasoning-budget jump from 768 to 960. In practice, that would mean longer planning, harder tasks and more capable agent workflows. Other reported changes include a December 2025 knowledge cutoff, Playwright support for browser automation and stronger browser capabilities for coding, research and scraping.
Nauti's Take
This sounds like a real jump, but also like leak-driven marketing with big claims and limited verifiable detail. The interesting part is not the number 960; it is whether GPT-5.6 Pro actually plans more cleanly, fails less often and runs browser automation reliably.
If that lands, ChatGPT becomes more of a work engine. If not, it is just a larger model with familiar rough edges.
Briefingshow
If the leak is accurate, the race moves less around better chat replies and more around actual work capacity: planning, browsing, testing and building. That matters for developers, research teams and agent workflows because a bigger reasoning budget only helps if tool use and error control improve with it. The report is still thin on hard evidence there.
