- Users across X report sharper outputs and unusually long response times in ChatGPT and Codex this week.
- Significantly improved web design and 3D video game outputs have been reported by some users from ChatGPT.
- A formal release for GPT-5.6 is rumored for next week, but OpenAI has yet to announce plans.
- Developer Anshu Chimala mentioned having early access to GPT-5.6 Pro, indicating potential advancements.
- Conor Dart reported a significant slowdown in generating a one-prompt 3D browser game, taking over an hour with GPT-5.6 Pro compared to 10 minutes with GPT-5.5 Pro.
- AI insider Chetas Lua also experienced a slowdown while testing a robotic simulation, suggesting results from the new model.
- Chris, an AI benchmarker, found that the suspected GPT-5.6 Pro took 87 minutes to complete a spaceship-building prompt, compared to 34 minutes and 42 seconds for GPT-5.5 Extra High.
- Leaker Pankaj Kumar suggested that GPT-5.6 may have a knowledge cutoff pushed to December 2025 and a new reasoning-effort setting called "Juice Value" raised to 960.
Users across X have reported sharper outputs and longer response times in ChatGPT and Codex this week, fueling speculation about the upcoming GPT-5.6 release.1
Developer Anshu Chimala shared his experience, stating, "Well well well, I'm one of the lucky ones with early GPT-5.6 Pro access."4
Conor Dart, another user, tested the model with a one-prompt 3D browser game that took over an hour to generate, compared to the usual 10 minutes with GPT-5.5 Pro.5
AI insider Chetas Lua also noted a slowdown while testing a robotic simulation, suggesting that the results stem from the new model: “GPT 5.6 Pro continues to mog in 3D test,” he remarked.6
Chris, an AI benchmarker, conducted a spaceship-building prompt test, where the suspected GPT-5.6 Pro took 87 minutes compared to GPT-5.5 Extra High's 34 minutes and 42 seconds.7
Additionally, a post from leaker Pankaj Kumar hinted at a knowledge cutoff pushed to December 2025 and a new reasoning-effort setting dubbed "Juice Value", allegedly raised to 960 from 768.8
As anticipation builds, users eagerly await OpenAI's formal announcement regarding GPT-5.6, rumored for next week.
“Users are experiencing sharper outputs and unusually long response times in ChatGPT and Codex this week. Rumors suggest a formal release for GPT-5.6 is expected soon, with significant improvements in performance.”
