AI weekly: OpenAI dots, America.gov, Claude Opus 5.5 and Sonnet 5.5

358 tweets liked between September 20 and September 29, filtered down to what’s worth knowing (here’s how the pipeline works). AI for Everyone OpenAI Launched Dots at DevDay, and My Feed Shrugged OpenAI introduced dots, always-on agents powered by GPT-6 Astra, its top model. Each dot has its own cloud computer and browser, works across 4,000+ apps through ChatGPT plugins, and runs around the clock, and you set what it does alone, when it asks first, and what it never does. OpenAI lists Pro, Business Premium, and Enterprise as the plans, but as of 5:45 pm Eastern on Sep 29 nobody I could find had access yet. OpenAI’s Tibo Sottiaux says it won’t draw down your usage limits. Sam Altman had teased “a new thing” the night before, and the reactions I liked afterward were mostly flat. Ibrahim Ahmed called DevDay “super underwhelming” and short on ambition. NIK summed up dots as costing $200 to do what Muse, Meta’s agent, does for free, and noted the second live demo flopped too. Muse already had its own cloud VM, connectors, and Mac computer use, and SpaceXAI’s Grok Bot shipped team agents the day before, while dot teams are “soon.” Even the name may be taken: the rumor is that SpaceXAI bought dot.com, and the domain now redirects to the Grok Bot download page. I checked the redirect myself, but the purchase is unconfirmed. (source: @OpenAI) ...

AI weekly: Jev out of stealth, Muse goes nationwide, SEC opens tokenized stocks

307 tweets liked between September 11 and September 20, filtered down to what’s worth knowing (here’s how the pipeline works). What I Shipped I launched Musecases, a place to share prompts for agents that have their own virtual machine. You post a prompt that worked, other people copy it. Submissions are auto-moderated for quality and harmful content by Jev, the decision model from TypeSafe covered below, which turned out to be the right tool for the job since moderation is a typed yes/no question, not an essay. I administer the whole app from Muse itself: moderation queue, tags, and the daily rankings all get handled by asking my agent. It is not affiliated with Muse.ai or Meta. Alexandr Wang, Meta’s chief AI officer, shared it on Thursday, which is how most of this week’s traffic found it. (source: @muse_cases) ...

X is still the best way I’ve found to keep up with AI. I like tweets throughout the week, then use Claude Code to pull those likes automatically and help me pull the signal out of the noise for this post (here’s how the pipeline works). This week it was 258 tweets between September 4 and September 11. The previous roundup (September 4) asked whether GPT-6 Astra is AGI. This week OpenAI answered with a math result that would have sounded like science fiction a year ago, and then spent the rest of the week arguing with a mathematician about how it got there. Underneath that, DeepSeek shipped an open model that costs pennies, Meta shipped a personal agent with a free tier, and OpenAI ran out of capacity to sell. ...

AI weekly: Is GPT-6 Astra AGI? Three rival flagships in four days, Nvidia buys Hugging Face

X is still the best way I’ve found to keep up with AI. I like tweets throughout the week, then use Claude Code to pull those likes automatically and help me turn the ones worth knowing about into this post (here’s how the pipeline works). This week it was 223 tweets in four days, roughly two and a half times the usual rate. That is why this one is early and longer than normal. The previous roundup (August 31) went out Monday morning. Since then, OpenAI, Anthropic, Meta, and Google have each shipped a flagship model, Nvidia has agreed to buy the place the open-source AI world keeps its models, and the US government has taken a side in the biggest AI copyright case in the country. Four days. ...

Check out the previous roundup (August 13) if you missed it. Last time the story was frontier prices collapsing. This week the price went to zero, because the model you’d have paid for is now a 17GB file on your hard drive, and the companies building serious products started treating that as the default rather than the fallback. ...
