Codex now works directly in Chrome on macOS and Windows. It’s even better at working with apps and sites in Chrome, and now works in parallel across tabs in the background without taking over your browser. To get started, install the Chrome plugin in the Codex app.↗

The more I replace plans with prototypes, the better the outputs Who'd have thought that low fidelity prototypes were better than walls of spec Oh yeah, the entire industry for 20 years Stop going against decades of knowledge because someone in SF shipped it as a 'mode'↗

Real-time World Models are the next AI frontier. Today, we're taking the first step towards this reality: our early preview lets you experience worlds generated in real-time, running on our global low-latency infrastructure. Try it now: reactor.inc↗

"Technical writing completely changed my life." - @trq212 In under 2 years, Thariq (@AnthropicAI) cracked the code on writing technical articles that consistently hit 1M+ views. In this 20-min workshop, he breaks down: → his exact writing workflow → the tactics behind article…↗

Introducing GPT-Realtime-2 in the API: our most intelligent voice model yet, bringing GPT-5-class reasoning to voice agents. Voice agents are now real-time collaborators that can listen, reason, and solve complex problems as conversations unfold. Now available in the API alongs…↗

New Anthropic research: Natural Language Autoencoders. Models like Claude talk in words but think in numbers. The numbers—called activations—encode Claude’s thoughts, but not in a language we can read. Here, we train Claude to translate its activations into human-readable text.↗

Introducing the Printing Press, a CLI-factory and a CLI-library. Built with @trevin. 🏭🖨📚 Most APIs suck for agents. Most MCPs suck for agents. Most official CLIs suck for agents. They waste tokens and time. @steipete started making his own because of this. 📚 A Library of ag…↗

Today, we’re announcing the general availability of the Parallel Monitor API. The web is shifting from pull to push, and agents are coming online. This release marks a major step towards a more proactive model, where the web pushes updates directly to your background agent. Mon…↗

Easy recipe you can steal for the animated side-notes on GTM Atlas by @attio → rough-notation by @preetster for the animated brackets → tegaki by @gkurttech for the hand-drawn text → IntersectionObserver to trigger on view↗

For the past several months, our engineering team has been building a new agentic coding system designed around a simple idea: the self-driving codebase. These aren't just agents to write code on demand. They detect triggers, spin up secure sandboxes, gather dynamic context, ope…↗

Strong Opinions, Loosely Held on Agent + Harness Engineering: 1. You can outperform any default harness+model (including codex & claude code) on pretty much any Task by engineering the harness around it. Using the exact same model, curate prompts, tools, skills, hooks for that…↗

We're excited to publish new research on agentic search. We found that nearly 50% of an agent's tool calls read and search for code and files. So then why does it take coding agents so long to find the right file? We thought the bottleneck was slow code search. But after inves…↗

The new @digg alpha is coming soon. First up: AI news. 9M+ graph connections. 15+ AI judges. Real-time X ingestion. Sentiment analysis, clustering, and signal detection built to surface what actually matters.↗

Hovercraft is how I always wanted to share my slides. So I made it. It’s a virtual camera for the Mac. No more disembodied voice. No more “can you see my screen?” Just me, tossing around my windows like it’s 2027.↗

@supabase/server is in public beta. This is a new package that handles auth verification, client setup, request context, and common server-side boilerplate for you. It works across Edge Functions, Cloudflare Workers, Hono and Bun. supabase.com/blog/introduci…↗

The Exa MCP is now officially available in ChatGPT! Exa gives ChatGPT access to unique data sources like people, companies, papers, and more. We find it particularly useful inside of Deep Research. To install, search “Exa” in “Apps”↗

Introducing GTM Atlas. GTM is going through its biggest transition in decades. Everyone used to work from the same stack, so everyone ran a version of the same system. AI has collapsed that gap completely, and the one-size-fits-all era is over. We’ve spoken to the most innovati…↗

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.↗

PostHog Code and the self-driving product Yesterday, we released [PostHog Code](posthog.com/code) to beta. It's a desktop app that runs coding agents on top of your product data. The obvious stuff ships itself. The tricky stuff shows up as a prioritized to-do list for you to s…↗

Three months ago, Codex was trash for knowledge work. Now it's my daily driver. I use it for writing, recruiting, deep engineering work, and everything in between. It even keeps me at inbox 0. I chatted with @every's head of growth Austin @tedescau on @every's AI & I about what…↗

AI supercomputers need a new kind of network to stay in sync at massive scale. OpenAI’s @markjhandley and @poyntingatgreg join @AndrewMayne to discuss what it takes to move data across record numbers of chips reliably and efficiently, the new Multipath Reliable Connection (MRC)…↗

I was talking with @josephruscio on the @heavybit podcast the other day when I realized that vibe coding and agentic engineering have started to blur a bit in some of my work - I published some extracts from the transcript simonwillison.net/2026/May/6/vib…↗

@bentossell for rendering, prefer text/plain on multipart emails first. for newsletters where HTML is unavoidable, @mozilla/readability strips the noise better than most parsers↗
