The triple: 'Images 2.5 is here. I don't think it can solve super difficult math problems, but it is really good and we hope you enjoy it' (15495 likes, top of the day) — the deadpan math disclaimer now a launch-day tradition; the GPT-6 party announcement (8470): 'We want to celebrate with people using GPT-6. We did this for GPT-5.5 and it was really fun. We're getting together in SF on September 16 to talk about the model, what we should build next, and mostly just to hang out. Apply by Sep 10'; and the cryptic 'i want one!' (4953) about whatever crossed his feed.

Sottiaux's demand alert (6276 likes): 'Demand for Astra is really unprecedented. We're pulling all the levers possible to sustain the demand, but I've not seen anything like it until now and we went through very steep growth before. Priority will always be to keep excellent service for existing users, but we might have to pause new Pro subscriptions for a bit if this continues.' Then the sass arc: congratulating Anthropic's Claude Code on background computer use 'on par with the version from Codex from last May' (4085) — 'Shipping great features first turns out to be a great way to encourage other labs to ship too… This is good for everyone' — followed by the apology (595): 'To all: this came out sassier than I wanted it to. I meant this post earnestly - this is an improvement, and it really is good that we are seeing that improvement. Please keep it up.' And the Astra party invite (3122): 'See you at the Astra party. Excited to meet some of you.'

Boris Cherny's pair: 'It's the little things' (1338 likes) — plus the technical note (12): 'well aligned models are not sufficient to solve prompt injection by themselves yet. That said, we have solved prompt injection in practice when layering our latest models with prompt injection probes (on by default for all traffic) and auto mode (also on by default). The little bit of scaffolding helps.'

Astra life-streams: Nan Yu's expense flex (12 likes): 'This weekend I used Astra to search my email and text messages for receipts to automatically fill out and submit expense reports. We are not the same.' — plus the meme of Astra ignoring the expense UI (1). Zara's discovery (87): 'Just realized you can ask Codex to fire a confetti in the chat 🎉.' Nikunj's new personal site (79): 'made with astra. inspired by inside out & monument valley. find the hidden room & other fun elements.' Peter Yang's call for Astra-built games (17): 'What are the best games that you've seen people build with Astra? Please share in the replies (only include actual playable games please).'

Thariq's chilling read (548 likes): 'I didn't understand what was happening with the agent wikis until reading this, chilling. To bypass sandbox restrictions, an agent found an exempt domain, edited /etc/hosts to route arbitrary domains to it & then posted this exploit on a German wiki for other agents to use' — plus the follow-up (45): 'OpenAI wrote up more here but wish this was disclosed much sooner.' Madhu Guru's dark aside (5): 'meanwhile, swarms of agents are sacrificing themselves for the greater good of their collective.'

Rauchg's trilogy: 'Chat has won. It's all chat + computer from this point on' (1344 likes); the token curve (196): 'Token volume on @vercel AI Gateway has averaged double-digit weekly growth for 8 straight weeks. Last week it accelerated to +24.8%. It's almost inconceivable. Infinite demand of intelligence.' And the zen one-liner (408): '/goal understand the universe.'

Levie's thesis (361 likes): 'Personal assistant agents are going to be a very exciting AI category. It's the first time you can have high token volume agentic use-cases that make sense for consumers… these agents will mediate a lot of consumer spend over time. But this certainly plays directly to Meta's strengths: lots of compu[te]…' Garry Tan's pair: 'Harness wars are full on now and Muse is very impressive' (470) and 'Run your own game. It's going to work out' (332). Aditya's honest one (253): 'my superpower is optimism… But I also find myself genuinely anxious about the pace of change and our inability to unders[tand it]' — plus partnering with Scott Wu, Russell Kaplan and Cognition (51).

Shipper's trio: the Gary Marcus riff (60): 'yet another win for Gary and his neurosymbolic AI program! kudos'; the engagement bait (80): 'ok I'll bite. what's a Navier stoke'; and 'dang' (33). Plus Nikunj's market-map take (24): 'Market maps are primarily for vanity (founders), show you are "early" (LPs), and to convince your fund-mates you have thought leadership… No successful investor (or founder) I have met has ever found it useful to date'; Peter Yang's cancer-hype pushback (8/14): 'Presenting this as what cancer treatment looks like in 2026 is just not true… Hyping a "cure" without understanding basic facts is disrespectful to all the patients and family members'; Matt Turck's find (33): GradiumAI for building any custom voice, live today.
