GPT-5.6 Pro Leaks Expose a Massive Jump in AI Reasoning Power
TL;DR
Geeky Gadgets reports a leak about ChatGPT 5.6 Pro, allegedly planned for June 25, 2026. The article does not provide official OpenAI confirmation. The most concrete claim is a reasoning budget increase from 768 to 960, which could support longer planning, harder task chains and stronger agentic workflows. The leak also mentions Playwright integration, improved browser capabilities, a December 2025 knowledge cutoff and testing through Kindle Alpha, Kepler Alpha and GPT-5.5 Pro accounts.
Nauti's Take
The interesting part is not the number 960 by itself, but the direction: more thinking budget plus browser tools means models are increasingly executing work, not just producing text. That is where productivity appears, and where risk grows too.
The article is clearly leak-heavy and partly PR-shaped; anyone making product or workflow decisions should wait for real benchmarks, pricing and limits.
Briefingshow
If the reasoning budget increase is real, ChatGPT moves further from quick-answer assistant toward long-running operator. Browser and Playwright capabilities would matter because they bring AI closer to real software testing, research and workflow automation. But without official data, this remains a leak story, not a confirmed product assessment.
