@itsolelehmann We’re always experimenting with new ideas. 90% don’t ship because we don’t think they’re good enough experiences. Still on the fence about this one — should we ship it?

i can't believe more people aren't talking about this part of the claude code leak there's a hidden feature in the source code called KAIROS, and it basically shows you anthropic's endgame KAIROS is an always-on, *proactive* Claude that does things without you asking it to. it runs in the background 24/7 while you work (or sleep) anthropic hasn't turned it on to the public yet, but the code is fully built here's how it works: every few seconds, KAIROS gets a heartbeat. basically a prompt that says "anything worth doing right now?" it looks at what's happening and makes a call: do something, or stay quiet if it acts, it can fix errors in your code, respond to messages, update files, run tasks... basically anything claude code can already do, just without you telling it to but here's what makes KAIROS different from regular claude code: it has (at least) 3 exclusive tools that regular claude code doesn't get: 1. push notifications, so it can reach you on your phone or desktop even when you're not in the terminal 2. file delivery, so it can send you things it created without you asking for them 3. pull request subscriptions, so it can watch your github and react to code changes on its own regular claude code can only talk to you when you talk to it. KAIROS can tap you on the shoulder and it keeps daily logs of everything. > what it noticed > what it decided > what it did append-only, meaning it can't erase its own history (you can read everything) at night it runs something the code literally calls "autoDream." where it consolidates what it learned during the day and reorganizes its memory while you sleep and it persists across sessions. close your laptop friday, open it monday, it's been working the whole time think about what this means in practice: > you're asleep and your website goes down. KAIROS detects it, restarts the server, and sends you a notification. by the time you see it, it's already back up > you get a customer complaint email at 2am. KAIROS reads it, sends the reply, and logs what it did. you wake up and it's already resolved > your stripe subscription page has a typo that's been live for 3 days. KAIROS spots it, fixes it, and logs the change endless use-cases, it's essentially a co-founder who never sleeps the codebase has this fully built and gated behind internal feature flags called PROACTIVE and KAIROS i think this is probably the clearest signal yet for where all ai tools are going. we are heading into the "post-prompting" era where the ai just works for you in the background like an all-knowing teammate who notices and handles everything, before you even think to ask

Run agents they said. You'll reclaim your time they said. I was up until 4AM monitoring my agents and thinking of new cool things to build. I no longer want to sleep.

I sincerely hope this leads to a mass talent exodus from OAI to Anthropic. Until now, it was possible to brush off Anthropic’s principles as empty promises — they sounded good, but in some sense they were still untested. Sure, Anthropic had delayed certain features (like giving Claude access to the internet) while they pursued additional safety testing, but it wasn’t clear if that approach would hold when real pressure arrived. But now the answer is clear: Anthropic is an organization with principles, one that is willing to put their money where their mouth is. Dario will stand up to an administration that has cowed every other notable tech leader into submission, including Sam. I am personally terrified of what AI will mean for the world. I’m not sure anyone, no matter how principled, can effectively steer the ship. But I do know that Sam and OAI definitively cannot. Sam serves Moloch knowingly — he does so with no reservations. So, if I have to entrust this ship to anyone, it’d be Dario. He, along with all the incredible folks I’ve gotten to know at Anthropic, are the reason I still have hope for the future.

Tonight, we reached an agreement with the Department of War to deploy our models in their classified network. In all of our interactions, the DoW displayed a deep respect for safety and a desire to partner to achieve the best possible outcome. AI safety and wide distribution of benefits are the core of our mission. Two of our most important safety principles are prohibitions on domestic mass surveillance and human responsibility for the use of force, including for autonomous weapon systems. The DoW agrees with these principles, reflects them in law and policy, and we put them into our agreement. We also will build technical safeguards to ensure our models behave as they should, which the DoW also wanted. We will deploy FDEs to help with our models and to ensure their safety, we will deploy on cloud networks only. We are asking the DoW to offer these same terms to all AI companies, which in our opinion we think everyone should be willing to accept. We have expressed our strong desire to see things de-escalate away from legal and governmental actions and towards reasonable agreements. We remain committed to serve all of humanity as best we can. The world is a complicated, messy, and sometimes dangerous place.

We shipped Claude Code as a research preview a year ago today. Developers have used it to build weekend projects, ship production apps, write code at the world's largest companies, and help plan a Mars rover drive. We built it, and you showed us what it was for.

if you are a software engineer and don't marvel every day at how much you can do thanks to AI and all the tools available to you now maybe you are not that good of a software engineer idk

@clairevo Where did you get your hidden talent screenshot? Looks like something that would be useful come performance review time.

Let me tell you a dirty secret about a lot of execs: They're extremely smart. And they haven't had to do their own work for years. Look inside any mid->large size company and you'll find VP+ executives that were promoted fast and furious in their early career because they're smart, hard working, make good decisions, have good taste, and can manage up down and sideways well. And as they become more senior, they start to earn the "you're too important to [X]" executive scaffold: - EAs for admin/scheduling/todos - Chief of Staff to keep their directs on track - Sr. leaders working under them eager for opportunity, so take on projects, presentations, meetings, etc. They're still smart, and they're still hard working, and they still make good decisions, so they tend to orchestrate and use these tools at their disposal quite well, choosing what gets done by whom. But - they show up to board meetings with decks made by their team - they show up to sales meetings with prep docs done by the sales person - they share insights generated by some data team - they +@[ea] to schedule every meeting - someone reads & responds to their emails And their job becomes - charm customers - charm candidates - charm the team - charm the board - charm the market - have good ideas (for someone else to do) And before someone shouts "this just optimizes for people who are highly political!" I must emphasize: these people are still usually wicked smart, they're usually extremely charming, and they work really hard (earliest on, latest off.) They hang in the forest, not a tree. Their experience saves your butt once or twice. They just don't have to put their hands on a keyboard and do the things. Sometimes they *can't* put their hands on a keyboard and do the things, because they're in endless meetings and on endless trips to do the charming/idea things. But after awhile of this, their "doing the things" muscle atrophies. Your CMO can't write compelling copy. Your CPO doesn't look at designs anymore. Your CRO can't login to demo. Your VPE doesn't have the latest local env setup. And over time, as an exec, your ability to be wicked smart degrades with your distance from the work, especially when things like AI come and smack your team in the face. This is all to say, I have two warnings for you if you've made it this far: EXECS: Do not stop doing the things. Take on projects, write your docs, do your own damn analysis, and don't stop touching the work. Fix your calendar so you're not just bopping meeting to meeting, and use that big brain of yours do actually build something. TEAMS: Consider yourself lucky if you have a leadership team that can still/wants to do the things. Trust: you'd rather have a micromanagey CEO who drops suggested edits in your doc than a manager-class exec team that doesn't even know your doc exists. Your company will be better for the work, the specificity, the care that comes with a doing-the-things leadership team, than a organizes-the-work leadership team. And for all of you: AI will generate a little microcosm of the dynamic above, but for IC work. I love AI, but still think it's important to exercise the muscle daily of writing, coding, reading, speaking, thinking. All unused skills will atrophy. Make sure you get stronger, not weaker, with these new tools. Ok back to doing things 😎
