For my first post, I’m sharing a letter @NVIDIA signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.…↗

Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price. https://t.co/GQWhcq2CQL↗

Open-weight models are essential to a healthy AI ecosystem. Together with others across our industry, we are outlining a path for open-weight models to strengthen American competitiveness and expand economic opportunity, while protecting national security. https://t.co/Tr0sAzAxT…↗

The new rules of context engineering for Claude 5 models I’ve written previously about how to best [prompt the newest generation of Claude 5 models](https://x.com/trq212/status/2073100352921215386) and work with them iteratively to discover what you want to build. But when you…↗

🚨 JAILBREAK ALERT 🚨 EVERYONE: PWNED 🫶 ALL: LIBERATED 🍄 Alright, this is a special one, so we’re gonna do things a bit differently than usual. Long story short, I’m sitting on a universal jailbreak technique that’s effective on ALL models, including heavily guardrailed fla…↗

Announcing OpenWorker! An open-source agent that doesn't just chat with you, but delivers finished work -- like hand you a polished document, send a slack message, or update a calendar entry. Ask it to prepare a customer brief, untangle your calendar, draft a report, or triage …↗

Claude Opus 5 one-shotted this game. EVERYTHING you see in this demo is custom code... not a single external asset was used. AI games are going to be amazing. (sound on)↗

Capitalism is just so beautiful. $8 trillion worth of market cap coming out in support of open-weight models because it's good for their business and makes them look good... and, totally coincidentally, it also happens to be better for us consumers and practically every busi…↗

How are we feeling about Opus 5 so far?↗

BREAKING: Claude Opus 5 is OUT NOW! And…it’s a hard model to love. We’ve spent the last week @every testing it across coding, writing, knowledge work, and our internal agent. It argued with instructions, stopped before the work was finished, and generally didn’t play well wit…↗

Something that AI unlocks is being able to try a few different variations of a feature quickly. I often ask my coding agent to come up with a few different variants and add a switcher so I can easily swap between them. It also saves your selection as a query param so I can sho…↗
