It solved 10 open math/CS problems that have stood for decades. Including proving non-sofic groups exist — a question that’s been open since 1999. OpenAI published a 249-page paper with machine-checkable proofs on GitHub. Total compute cost for all ten: ~$2,000. Let that sink in — problems that stumped mathematicians for 27 years, solved for less than a MacBook. It’s not a chatbot, it’s a system. Multiple agents working together for hours or days on one problem planning, testing, revising, without you babysitting it. Compare that to 5.6, which (per leaks) still gets “ADHD” on long tasks — sets a goal, comes back 10 hours later, hasn’t finished it. Sam already showed it to DC policymakers. Astra is expected to be one of the first models run through the new federal pre-release review process. That alone tells you they think this one’s a different category of capability. No release date. No confirmed name. Could be GPT-6, could be a GPT-5.7 branch. OpenAI’s own naming ladder so far: Luna → Terra → Sol → Astra (each tier faster/dumber to slower/smarter). Here’s my take: we’ve spent this whole year optimizing prompts and routing to cheap models. That era’s ending. The next unlock isn’t “which model is cheapest” — it’s “which model can actually be trusted to run unsupervised for days.” That’s a completely different skill set to build around. Get comfortable with agentic/long-horizon workflows now. That’s where this is headed. 🧵

I built 8 apps alone. I made $3. And I bought it myself. That's not a joke. My only "sale" was me buying my own in-app purchase to test it. Had to cancel and refund it. That's the entire revenue history of seven months of building. I just posted the full breakdown on YouTube real App Store Connect screenshots, all 8 builds, no fake numbers. But I wanted to say the important part here first, because you're the reason I made it. I thought vibe coding was my advantage. It let me build fast and it made me feel productive. One app pulled thousands of impressions and made nothing, because there was nobody on the other side of it. No one to tell me what was broken. No one waiting for v2. TikTok gave me reach, but reach is one-way a video, then a funny clip, then some news, then you're gone. You can't build trust in a feed that fragmented. What I was missing wasn't code. It was a room. People I see every day, who'll tell me the truth, who I can actually launch something to. So that's what this is. I'm building the room first this time, and I'm building it in front of you. Question for you: what's something you've built that nobody's using? Doesn't matter if it's an app, a landing page, a spreadsheet, a half-finished repo. Drop it below I'll look at every single one and tell you honestly what I think is missing. That's the deal. Luke

If there were backdoors and biases hidden in open-weight models, you could count on closed-weight labs to find and reveal them - naval Intelligence is everywhere every model currently very capable of doing anything Smartest will realize that efficiency and open source will win long term Glad you could join and support we got a bright future ahead- Luke

Opus 5 shipped today. Half the price of Anthropic’s top-tier model, matching it on most real work. I’ll get to why that matters. First, something smaller. Yesterday I gave it [THE ACTUAL TASK]. Something I’d normally block out half a day for. It came back in twenty minutes and the output was better than what I’d have shipped tired at 11pm. Not an “AI will replace all jobs” moment. A boring, specific, Tuesday-afternoon one. The gap between “I have an idea” and “the idea exists” just collapsed, and most people are still using this thing like a search bar. That’s why today matters. The whole game is no longer which model is strongest it’s which task goes where. Route wrong and you pay double for work that didn’t need it. Every comparison article ranking right now was written before Opus 5 existed. A few still claim it was never released. So I redrew the map: which tasks land on which model, what the benchmarks actually say, and the one factor that decides it for anyone under an NDA that nobody’s putting in a thumbnail. What’s the highest leverage thing you’ve pointed it at this week? Genuinely curious half the value in here is seeing what other people are aiming it at, not what I think about it.
