Announcing Built with Opus 4.6: a Claude Code virtual hackathon. Join the Claude Code team for a week of building. Winners will be hand-selected to win $100K in Claude API credits. Apply here: https://cerebralvalley.ai/e/claude-code-…

Introducing Claude Opus 4.6. Our smartest model got an upgrade. Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes. It’s also our first Opus-class model with 1M token context in beta.

Genie 3 🤝 @Waymo The Waymo World Model generates photorealistic, interactive environments to train autonomous vehicles. This helps the cars navigate rare, unpredictable events before encountering them in reality. 🧵

ok this is weird new app called " rent a human" ai agents "rent" humans to do work for them IRL 1. humans make profile skills, location, rated 2. agents find humans with mcp/api & give instructions 3. humans do tasks IRL 4. humans get paid in stablecoins etc instantly

Ads are coming to AI. But not to Claude. Keep thinking.

Over 300M people use ChatGPT to learn how to do something every week. More than half of US ChatGPT users say it enables them to achieve things that previously felt impossible. These are just a few stories of what they are building.

You can now customize your Infographics & Slide Decks in the @NotebookLM mobile app! 🥳 Tap the pencil icon to adjust the design, complexity, and narrative style of your outputs. From a business presentation to the perfect bedtime story, the possibilities are (nearly) endless!

Big drop for Codex users later today! You can just build things.

Sneak peek at some https://ui.sh stuff 🫣 This is our local development environment where we can compare what the models generate by default to what they generate with our opinions layered in. So much more to do, but already obvious improvements from just focusing on little details like hanging punctuation, card content alignment, lighting/elevation cues, and edge highlighting of avatars.

ElevenLabs started as a weekend project. They crossed $330M ARR in 2025 as they build the voice interface of the future. This is the ElevenLabs story. An a16z Original.

THE FUTURE OF EDUCATION: if i was 18 right now, I would only drop $200k to go to college if i NEEDED a credential at the end (doctor, lawyer etc), because there is alternative path that lets you learn 10x faster. you live inside claude code, you plug in openclaw so your agents run 24/7, you pick a stream like apps, writing, or research, and you spend your days directing systems instead of doing manual work. instead of $20k a semester, people will pay a few hundred dollars a month for access to compute, tooling, and just use X/YT for learning as much as possible and inspiration. you can still go to parties and meet people while your openclaw agents are running at home ;) education shifts from lectures to projects. your “degree” becomes the things you built, the systems you ran, and the outcomes you shipped. people will learn managing agent workflows, reviewing output, fixing mistakes, creative taste, building distribution, coming up with product clarity and deciding what to build next college education will be reserved for trust fund kids, people who can don't have pressure to earn a livelihood. but for those who feel the burning pressure to build/make a livelihood/make an impact, I bet they are hanging in claude code, codex, openclaw etc all day/every day.

I'm Boris and I created Claude Code. I wanted to quickly share a few tips for using Claude Code, sourced directly from the Claude Code team. The way the team uses Claude is different than how I use it. Remember: there is no one right way to use Claude Code -- everyones' setup is different. You should experiment to see what works for you!

The 5.3 lovefest is so nice to see. Don't think we've had so much excitement for a model since the original GPT-4.

First, the good part of the Anthropic ads: they are funny, and I laughed. But I wonder why Anthropic would go for something so clearly dishonest. Our most important principle for ads says that we won’t do exactly this; we would obviously never run ads in the way Anthropic depicts them. We are not stupid and we know our users would reject that. I guess it’s on brand for Anthropic doublespeak to use a deceptive ad to critique theoretical deceptive ads that aren’t real, but a Super Bowl ad is not where I would expect it. More importantly, we believe everyone deserves to use AI and are committed to free access, because we believe access creates agency. More Texans use ChatGPT for free than total people use Claude in the US, so we have a differently-shaped problem than they do. (If you want to pay for ChatGPT Plus or Pro, we don't show you ads.) Anthropic serves an expensive product to rich people. We are glad they do that and we are doing that too, but we also feel strongly that we need to bring AI to billions of people who can’t pay for subscriptions. Maybe even more importantly: Anthropic wants to control what people do with AI—they block companies they don't like from using their coding product (including us), they want to write the rules themselves for what people can and can't use AI for, and now they also want to tell other companies what their business models can be. We are committed to broad, democratic decision making in addition to access. We are also committed to building the most resilient ecosystem for advanced AI. We care a great deal about safe, broadly beneficial AGI, and we know the only way to get there is to work with the world to prepare. One authoritarian company won't get us there on their own, to say nothing of the other obvious risks. It is a dark path. As for our Super Bowl ad: it’s about builders, and how anyone can now build anything. We are enjoying watching so many people switch to Codex. There have now been 500,000 app downloads since launch on Monday, and we think builders are really going to love what’s coming in the next few weeks. I believe Codex is going to win. We will continue to work hard to make even more intelligence available for lower and lower prices to our users. This time belongs to the builders, not the people who want to control them.

New Engineering blog: We tasked Opus 4.6 using agent teams to build a C compiler. Then we (mostly) walked away. Two weeks later, it worked on the Linux kernel. Here's what it taught us about the future of autonomous software development. Read more: https://anthropic.com/engineering/buildi……
