Power your browser agents with Stagehand v4 in OpenAI's official SDKs: docs.stagehand.dev/v4/integration…
Browser and computer use got waaaay easier in the latest @OpenAIDevs Python and Node.js SDKs 🧵
Use @OpenAI's computer-use and browser-use helpers with E2B to give your agent a private desktop in the cloud that you can watch live while the model clicks and types. Use it to help you complete tedious tasks in an application or test user flows: docs.e2b.dev/agents/openai-…

Let your app choose the right model, tool, or action in near real-time with Decisions API, now available to all developers in public beta. The Decisions API makes decisions up to 10x faster than GPT-6 Luna through the Responses API.
super excited to announce plugin extensions today 🎉 you can now use the exact same platform we use to build ChatGPT features like meetings, health, finance, and many others 🤯 all based on the same MCP & MCP Apps you’re already used to: github.com/openai/mcp-ext…
Please welcome GPT-6 Sol and GPT-6 Luna to the GPT-6 universe. GPT-6 Sol and Luna build on the advances behind GPT-6 Astra, bringing much of its strengths into faster and more affordable models to support work at scale. We’ve also made caching and inference more efficient, and we’re passing the savings directly to you: 50% lower API prices for Sol and Luna compared with GPT‑5.6 promotional pricing.
GPT-6 Sol and Luna just landed in Astra’s orbit. Both launch today with API prices 50% lower than GPT-5.6. Build with Sol. Scale with Luna. To production and beyond.
GPT-6 Astra is the best-performing model on FrontierSWE Astra achieves a score of 65.5%, outperforming Fable 5.1 (56.3%) and its predecessor GPT-5.6 Sol (32.2%)
Singularity
GPT-6 Astra is state-of-the-art on FrontierMath Tier 4, ARC-AGI 3, and TerminalBench-4.0. GPT‑6 Astra is also a major advance for scientific discovery, with state-of-the-art performance on Terminal-Bench Science 0.1 and HealthBench Pro.
GPT-6 Astra is here. We hope it will begin to enable a new generation of entrepreneurship, scientific discovery, and building. We believe it is the best model in the world for computer use, professional work, science, coding, cybersecurity, and more. It took us some extra time to ensure that we could meet the safety and alignment standards required for this capability level, but we think you’ll find it worth the wait. It scores 98% on FrontierMath Tier 4, 99.9% on ARC-AGI 3, and 100% on ExploitBench.
Bret Victor's "Inventing on Principle" (vimeo.com/906418692) changed how I think about developer tools. Faster feedback saves time, but it also changes which ideas developers are willing to try. Part 2 of the *Building for Developers* series: markstuart.dev/posts/bret-vic…
After years at PayPal, I've thought a lot about what @stripe changed. Its API, docs, test tools, logs, support, compatibility, and world-class design felt like one product. First up in my new "Building for Developers" series: markstuart.dev/posts/stripe-d…
Part 2 of *The Web We Inherited* is about ESLint. In 2014, while we were re-platforming PayPal into Node.js, @xjamundx showed us ESLint plugins and ASTs behind them. That experience still shapes how I think about extensible SDKs and developer platforms. markstuart.dev/posts/eslint-m…
jQuery Conference 2010 in Boston was my first web conference. I didn't realize it then, but an incredible amount of the web's future was sitting in that room. @jeresig, @paul_irish, and the community behind the code pushed me to start reading libraries from the inside out. Still remember youtube.com/watch?v=i_qE1i…!
I'm using my break between roles to revisit the libraries and moments that shaped the web, my career, and how I build APIs, SDKs, and developer platforms. The series is The Web We Inherited. First up: jQuery! markstuart.dev/posts/jquery-c…
Everyone is waking up to the fact that code-review is the bottleneck of 2026 I'm bullish on ramping review agents - but the vibes coming from - 0github.com - asi.review - pierre.co start to hit closer to home on where we need to go
@dmikeyanderson Tpain?? Ok I need to go to this.
Trying to visualize that Server-Side Rendering (SSR) isn't just about SEO, it actually makes the site faster. And why PPR is the goat. Main cost = 🟥 JS load & Hydration 🟡⇆🔵 Region Latency
@dmikeyanderson @carloscastrodev @burgessdryan @dmikeyanderson We were so punk rock! 🤘JS@PayPal’s living on at eBay :-) Organizing something just like it a month from now.
