The merge: Cat Wu's announcement (1206 likes): 'Today, we are merging Claude Cowork and chat to simplify how you use Claude! We are also integrating Claude Design so that you can ask Claude to make a Slide, Design, or Doc without needing to switch tabs or apps. Many of you shared that you didn't want to choose which Claude product to use for any task. As Claude models have become more capable, we've found that Claude can handle the routing for you.' Cherny's framing (1388): 'Claude Code showed that AI could do real work, not just answer questions… Cowork proved knowledge workers could do the same: hand Claude the brief, come back to finished files. Today, chat and Cowork start merging into one Claude. The direction: one Claude that carries context across everything you're working on' — plus the feature note (2285): 'Also today: Claude Docs, Claude Slides, and Claude Design are in every conversation… There's no separate tool to navigate to. They're just in the chat.'

Claude official's triple (3305/498/462): 'You can now make decks, docs, and designs in your conversation. Draft the one-pager in Claude Docs, turn it into a deck with Claude Slides, and mock up a matching visual in Claude Design, all from one place'; 'Fix a line in the doc yourself, leave a comment for Claude on a slide, or select an element and move it… present the deck straight from Claude, export the doc, or share everything at one link'; and the migration note (462): 'If you've been working in Cowork, everything is where you left it: chats, projects, artifacts, connectors, and skills.' Alex Albert's verdict (182): 'The team did an amazing job with this merge. The resulting UX feels so much better than chat or Cowork did on their own.' Shipper's celebration pair (1658/1166): 'THEY DID IT. THE END OF THE TABS ERA IS UPON US' and 'big big big big big.'

Altman's tease (8692 likes, top of the day): 'the main thing i was excited about launching this week will be next week instead, but imo worth the wait!' Sottiaux's trio: the capacity truth (5415): 'Sometimes physics can't be cheated' — presumably on why capacity can't be conjured instantly; the Astra checklist (4485): 'Astra ✅ Fast ✅ Frontier ✅ Efficient ✅ For everyone'; and the philosophical one (1913): 'What is ChatGPT.' Zara's headwind (1830): 'I find myself using Claude less these days because the way it speaks has just become insufferable. Like it's constantly trying to showcase how smart/sophisticated it is, rather than actually communicating a point across.' Garry Tan's flex (512): 'I can use any harness I want and it's the same personality and full memory of my personal AGI.'

Rauchg's speed story (2855 likes): 'We're seeing extraordinary results from @typesafeai. Default mode in 𝚏𝚡 is auto, with a safety reviewer analyzing every command. That reviewer runs on GPT Luna today. Jev is up to 18x faster (p95) *and* more accurate. It's coming to @vercel AI Gateway and likely new default.' Thariq's trio: 'I think bash is no longer all you need, if your goal is just reliably tool calling. But sandboxes + bash are still good for work that involves code generation & execution' (356); the shape insight (63): 'increasingly you can just give Claude tools shaped in the way you want vs tricking it with a layer of indirection — e.g. for data storage do you really want a file system or do you want an API to a database. This is again an update to me from last year'; and the port note (46) on Claude Managed Agents.

Levie's horizon (102): 'Incredibly exciting that there are entire universes of AI innovation that still exist that weren't even on most of our radars. Being able to process information insanely quickly, at crazy low costs, with high levels of capability is huge for a wide number of enterprise tasks — data classification, routing decisions, quick judgment calls about safety or security…' Shipper's meme (308): 'LLMs are just jev is just a JSON autocomplete classifier 🤝 🚩.' Madhu's principle (4): 'Safety and security are *features* of your AI product and model — not guardrails that need to be imposed on you from the outside.' Aditya's pair (51/11): 'Great ideas rarely emerge from isolation' — and hosting CA governor candidate Steve Hilton at SPC.

Nikunj's trio: the birthday bake (158 likes): 'Wife wanted Black Forest cake for her birthday.. I haven't baked in a long long time, so not perfect but think it turned out ok (thanks @ChatGPT). Happy birthday @shimoleejhaveri — I love you mostest ❤️' — plus the tiramisu follow-up (5): 'Before she wakes up and corrects me, she never "wanted" it in the first place.. We threatened to make Tiramisu and that's when her preference spilled out. Sous chef had a great time eating half the batter 😂'; and the Home agent (44): 'Been tinkering with a "Home" @NousResearch agent for a few months and it's finally gotten really good.. It's also our first "group" bot where my wife and I interact with it on a daily basis — which has been fun learning especially when it fails 😅. I have tried to recreate with Grok Bot and similar and you can't get this level of granularity and control (e.g. only read certain emails, convert inline attachments to structured data or logged in browsers…)'

Peter Yang's trio: the podcast pipeline (25): 'I use these 8 AI skills to produce my entire podcast while still applying my taste and judgment along the way. 1. /podcast-prep does research on the guest and then preps an interview guide. 2. /podcast-edit reviews the raw transcript, then works with me to pick engaging quotes for the intro reel along with moments to cut. 3. /podcast-production orchestrates 5 skills to turn the full episode into 6 different assets. Some people think the lates[t]…' — plus the Once reading app for his 4.5-year-old (19) and the book recommendation (3).
