GPT-5.6 Pro Leaks Expose a Massive Jump in AI Reasoning Power
TL;DR
Geeky Gadgets, citing World of AI, says OpenAI is expected to release ChatGPT 5.6 Pro on June 25, 2026. The source does not present this as officially confirmed by OpenAI. The headline leak is a reasoning budget increase from 768 to 960. In practice, that could mean longer planning chains, harder multi-step tasks and more stable agent workflows.
Nauti's Take
The interesting part is not the version number, but Playwright plus more reasoning. That would be a clear signal that OpenAI is still optimizing for agents that operate websites, run tests and push tasks through to completion.
Still, the leak should be read with restraint. As long as the evidence comes from a YouTube and blog ecosystem without official benchmarks, this is a watchlist item, not a buying argument.

If the leak is accurate, the shift is less about prettier chat and more about operational work: planning, browsing, testing, running code and controlling workflows. A larger reasoning budget matters because agents usually fail not on one step, but across long chains with context, tool errors and intermediate decisions. That is where AI moves from assistant to actual worker.
