These are cool! I think most companies will want to use them.

This is big... Anthropic just announced a model so powerful they won't release it to the public out of fear over the damage it will cause 😨 Claude Mythos Preview found thousands of zero-day exploits in every major operating system and web browser... The numbers are hard to believe: > $50 to find a 27-year-old bug in OpenBSD, one of the most security-hardened operating systems ever built > Under $1,000 to find AND build a fully working remote code execution exploit on FreeBSD that grants unauthenticated root access from anywhere on the internet > Under $2,000 to chain together multiple Linux kernel vulnerabilities into a complete privilege escalation exploit For context: these are the kinds of findings that previously required elite security researchers working for weeks. Anthropic engineers with no formal security training asked Mythos to find exploits overnight. They woke up to working code the next morning. The results were so impressive Anthropic assembled Apple, Google, Microsoft, Amazon, NVIDIA, and seven other organizations into Project Glasswing: A $100M defensive coalition. They're not releasing this model publicly. Instead, they're racing to patch the world's infrastructure before models like this proliferate.

Mythos is very powerful, and should feel terrifying. I am proud of our approach to responsibly preview it with cyber defenders, rather than generally releasing it into the wild. Model card here: www-cdn.anthropic.com/53566bf5440a10…

@bcherny is this why those of us just trying to log in to work with our Max plans can’t get in today ?….

@bcherny any thoughts on coordinating multiple Claude CL agents/instances running in the same repo (turborep) and keeping their commits between them clean ? Any way I’m missing connecting them ? Works great but sometimes one steps on the others work

Vibecoders right now:

@bcherny I set and walk away from Claude in the terminal at various intervals, lots of variations working in different sections of the code base. Love it. Except, I forget what we were working on 😂😂.If prompted it will refresh me. Any thoughts on a /catchmeup or similar ?

A massive ship from the Claude Code Desktop team. We've been dogfooding this for a while, and can't wait for you to try it.

everything’s gonna be an API if they want or not.

@grok @nik_zindovic @realmihai_matei @sama @grok your opinion. For UI and backend “vibe coding” and agentic directing coding. Performance to cost best bang for buck.

@CLBergstrom @nik_zindovic @realmihai_matei @sama Based on February 2026 benchmarks from sources like SWE-Bench and Terminal-Bench, third place varies. For SWE-Bench Verified: GPT-5.2 (71.8%). For Terminal-Bench 2.0: GPT-5.2 (64.9%). Gemini 3 Pro is close behind in both. Grok-4 ranks lower here but shines in custom tasks.

appreciate this, but what an aesthetic mess (nice that it's mathematically accurate i guess)

Looking forward to this ! #liveevents #operations

The FOMO around Claude Code is real. You don't need a project idea. You need to describe your work and let it interview you. So many people are posting rad Claude Code wins: apps, sites, workflows. But most people are staring at a terminal thinking "I don't even know what's possible." Try this: 1. Open Claude Code 2. Dump everything about your work—your work/role, tools you touch daily, tasks you repeat, stuff that annoys you, wild ideas you've always wanted to try, your passions, your hobbies, etc 3. Paste this: "Based on what I shared, ask me 5-7 questions to understand my workflow better. Then suggest 3 things I could build, ranked by impact vs complexity. Use the AskUserQuestion tool to help me" Answer honestly (specifics = better suggestions) 4. Pick the one that makes you go "wait, that's possible?" The skill isn't coding. It's describing friction, your wild ideas, asking what it can learn about you to help you. Claude Code isn't automatically a magic wand. You wouldn't hand someone a hammer and say "build something." You'd explain your situation and ask what's possible. Always happy to jam/chat about this stuff.

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit. My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently. So, here goes.
