New Anthropic research: A global workspace in language models. Of everything happening in your brain right now, only a tiny fraction is consciously accessible—thoughts you can describe, hold in mind, and reason with. We found a strikingly similar divide inside Claude.

Introducing Claude Science, a new app designed with every stage of research in mind. Artifacts traced to their code, environments managed on demand, and 60+ optional scientific databases that you can connect. Available now in beta.

🚨 Anthropic has created an entirely new category and they didn’t tell anyone. The system prompt leak is basically all the concrete information we have. Official docs stay deliberately vague. After digging deeper, it’s confirmed: Fable is running a mini Claude Code subsystem under the hood. It doesn’t chat. It executes a full agentic loop inside a sandboxed terminal: read files → write code → run bash → verify output → iterate While the rest of the industry is still benchmarking raw chat models, Fable has already moved into autonomous agentic workflows. #Fable5 #NewCategory #AgenticAI

🚨 Claude Fable 5 is NOT a vanilla LLM but an agentic system dressed as a regular model. A leaked system prompt (link in replies) confirms what many suspected: • Full Linux sandbox with bash & file editing • Persistent storage API + web/image search • Safety classifiers that

As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models. Here’s what this means for you: Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error. On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models. We know this is a disruption to your workflows; we appreciate your patience and support.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of

Imagine #XR that's smarter and more immersive than anything you've experienced before. Something new is coming 👀

Ironic: corporations replace humans with AI that “work continuously and never ask for raises.” But then Claude AI hard stops after 5 hours and automatically increase prices without notice.

JUST IN: Claude Opus 4.8 reportedly found a critical Zcash bug that could have allowed attackers to create unlimited coins.

Opus 4.8 just broke ARC-AGI-3 it tripled GPT-5.5's score we are now at a breathtaking 1.5% human efficiency

We’re expanding Project Glasswing. We’ve extended access to Claude Mythos Preview to approximately 150 additional organizations, based in more than fifteen countries. Read more about this expansion and our future plans for Project Glasswing: anthropic.com/news/expanding…

AI coding agents can write code, but they can't see if it actually works. Chrome DevTools for agents 1.0 fixes this. The stable release brings powerful browser debugging, emulation, and automated audits to your AI assistants via our Chrome DevTools MCP server. 👁️ Give your agent eyes on the runtime → goo.gle/42K7Rrl #GoogleIO

Today we’re releasing DeepSWE, a new standard for agentic coding benchmarks. On public leaderboards, top models often look relatively close in capability. DeepSWE shows where they actually diverge, reflecting the realistic experience of developers in their day-to-day work.

Hoy una industria entera dejó de tener sentido. Un tío publicó en GitHub un repo que convierte cualquier foto en un mundo 3D explorable: meshes con físicas, splat del fondo, audio ambiente. Todo. Una imagen entra. Un mundo sale. Cinco minutos. La gente que se pasó diez años aprendiendo Blender lleva todo el día mirando esto en silencio. Se llama image-blaster.

40% of the code Claude writes for you is wasted. you're paying for the rewrite. a 65-line markdown file fixes it. 120,000 developers have starred it. the author tested it on "30 codebases over 6 weeks" and reported a mistake rate drop from 41% to either 11% or 3% depending on whether you read the headline or the body. the irony is that the article is right. CLAUDE.md is the most under-leveraged file in your stack. 65 lines of behavioral rules outperform a 4,000-token preferences dump. "be careful" is useless. testable imperatives are gold. "be senior" doesn't work Claude already thinks it is. the 4 rules that ship the most leverage: / state assumptions, never guess silently / minimum code, nothing speculative / surgical changes, don't refactor adjacent code / define success, loop until verified compliance: ~80%. mistake rate: from ~40% to single digits. no human caught the contradicting numbers in the title. nobody had to.

The senior QA engineer spent eighteen months building "TestGenie" An internal AI tool that could automate regression testing across their entire platform She fed it 847,000 test cases her team had written over six years Every edge case, every bug scenario, every critical path they'd discovered through blood and sweat TestGenie learned from forty QA engineers' collective knowledge Then it got good Really fucking good 95% test coverage with zero human intervention Management called an all-hands last Tuesday "We're excited to announce TestGenie has exceeded all performance metrics" "Unfortunately this means we're eliminating the QA organization effective Friday" Forty people who trained their own executioner The engineer who built it? She's getting laid off too "Role redundancy due to automation optimization" Her final Slack before badge deactivation: "TestGenie-QA-Sarah is now live in production" They named the tool after her as a "tribute to her innovation" She's 34 years old and just automated herself into unemployment But hey, TestGenie saves the company $8.2 million annually in QA salaries

A Google DeepMind researcher cornered me at a bar in Hayes Valley I was showing my Polymarket PNL to a friend. She leaned over. Didn't introduce herself. "That's not a trading app. Show me your stack" I told her. Claude Code. Four repos. $25 a month. She set down her drink. "We tested this internally. You connect Claude directly to a dataset. It builds its own detectors. But nobody ships it because compliance kills everything" I asked what she meant. She took my phone. Opened one link. github.com/warproxxx/poly… 86 million trades. Every wallet. Every entry. Every exit. "You don't tell Claude what to look for. It finds the wallets that win. Then it finds WHY they win. Then it copies the pattern" Her team spent 9 months building this for a hedge fund. 14 people. $2M budget. "The part that took us the longest - exit logic. Everyone thinks entries matter. They don't. Exits are the entire game" I told her my bot cuts at 85% of expected move or on a 3x volume spike. She went quiet. "Who taught you that" Claude Code found it in poly_data. Top wallets exit before resolution 91% of the time. They capture the move and leave. She opened another link. github.com/Polymarket/pol… "This is the scanner. Three commands. 500+ markets. No API key. Claude scores them in 20 minutes" "That's our exact infra. Except it took us 9 months and you did it in a weekend" My setup: Claude API - $20/mo VPS - $5/mo poly_data - free polymarket-cli - free 19 days. 4 agents. 74% win rate. Copytrade here: kreo.app/@lunar I showed her the article where I broke down every repo, every command, every dollar. She read it for five minutes. Then: "You just open-sourced our entire pipeline" She texted me the next day. "My team lead saw your thread. Take it down" Too late.

🚨 Sam Altman literally gave a 43-minute masterclass on turning ideas into billion-dollar companies. Most people will never watch it. And instead of hype, he broke down what actually makes startups work. No fluff. Just reality. He explained that ideas don’t matter nearly as much as execution. The difference between something small and something massive isn’t the idea it’s how relentlessly it’s built and improved over time. He also emphasized that the best founders don’t chase everything. They focus on one thing that truly matters and push it forward with extreme clarity. Distraction kills more startups than competition ever will. And then there’s scale. Truly big companies aren’t built for a niche they solve problems that millions of people care about. If the market isn’t large enough, the outcome won’t be either. His biggest insight? Startups don’t win because they’re smarter they win because they stay in the game longer and iterate faster. That’s why this masterclass stands out. Because while most people are waiting for the perfect idea… The best ones are already building.

This will work with both Claude Cowork and Claude Code Desktop. You can ask Claude to click all the buttons in a legacy app that you'd like to automate - or use it to help debug a native app you're working on. It's slow but giving Claude my mouse & keyboard is *so* exciting to me.

This is releasing to macOS today, Windows will follow in the next few weeks. The entire computer use field is early - Claude will move slowly and deliberately, much slower than a human does today. To try it out, download the app from claude.com/download
