I'm doing so many RL experiments with GPT-5.6 Sol I'm trying to mix emergent behavior with RL

OpenAI Build Week starts Monday — and we’re hosting two livestreams to help you build. First up: Join us on July 13 at 10am PT to get the hackathon overview, see Codex and GPT-5.6 in action, and choose what you’ll build. x.com/i/broadcasts/1…

just asked gpt-5.6 sol in cursor to set up blender mcp and make me a realistic floating macbook, then render the whole thing. never opened blender once in my life before today.

gpt 5.6 sol story of the day: i have a macbook connected and powered by a caldigit TS5 it kept reconnecting randomly and it was pissing me off, i told sol to investigate and it found out that it would disconnect when power heavy GPU loads and the caldigit couldn't supply enough power sol created the hypothesis and proved it to me then it told me to plugin the 120W power cable, then it did the reproductions again and they were fixed this would have taken me an entire day

@kedytcom 🚢

This weekend I built an iOS app with: - Astro for finding a trending niche - Codex for planning - Claude for design - Grok for code Then I localized the App Store listing for 36 markets. Now it’s waiting for App Store review. One person. One weekend. Four AI tools. 36 markets. Building apps is getting easier. Getting users is the real game now.

@he_the_mystery It will be recorded 🫡

@OpenAIDevs Could you confirm if this event will be recorded? It would be incredibly helpful for those of us in different time zones.

GPT-5.6 is now in Figma Make! My deeply-researched, very analytical take: It's good. It’s very good. Excited for you to try it out!

We could have made another shiny Three.js demo. Instead, we gave @OpenAI’s GPT 5.6 a vague CEO message from @kskrygan, a JetBrains IDE in the hands of @wordmandotdev , and five minutes to build something useful. GPT 5.6 is now available in JetBrains IDEs, Junie, and Air.

GPT 5.6 Sol is so good web design it actually broke our evals 🥲 took creative liberties like a supapro web designer that took us off guard. in a few prompts, it was able to remix a slurped brand from an URL and Sol lit up 🌞❤️‍🔥

NVIDIA teams run ChatGPT Work to automate workflows, surface insights faster, and cut operation costs. Our full-stack collaboration continues to scale. GPT-5.6 builds on GPT-5.5, trained and run on NVIDIA GB200 and GB300 NVL72 rack-scale systems. Congratulations to the @OpenAI team on the launch. 🎉

GPT-5.6 from @OpenAI is live in Magic Patterns! Our early evaluations show greater token efficiency and a meaningful uplift in design capability from GPT-5.5. Check out design examples generated by GPT-5.6 Sol in the blog post below:

GPT-5.6 tops the DeepSWE leaderboard at 73%. Sol, Terra, and Luna results are now available.

The GPT-5.6 model family is now available on Perplexity's Agent API. Every gain at the frontier compounds through Perplexity's API stack. The GPT-5.6 family sits on the Pareto frontier of our agentic research evals: higher accuracy at lower cost. As such, we've updated our Agent API Presets. xHigh, High, and Medium (our pre-configured presets for long-running research workloads) are now better, faster and cheaper on the GPT-5.6 model family.

From spoken spec to working service. Sam Kronick, an engineer on @tryramp’s Applied AI team, used GPT-5.6 to build an entire service end-to-end from a natural-language spec.

GPT‑5.6 took on a complex coding task spanning nearly 1,000 lines for Ankit Aich at @SnorkelAI, handling the work from start to finish without repeated prompting or hand-holding.
