@AnthropicAI what is the Pro plan meant for? In Claude Cowork, I couldn't get past ~30min doc iteration, and in Claude Code CLI, past a side panel execution with infra already in place (Sonnet) -> Plan mode consumed ~34%, so I dared not to execute, wrote the plan to file instead.

@MilksandMatcha It started as a dream: could I build without coding skills? Turns out I can. Now, I'm helping others! Creating apps and websites for my sons that are new entrepreneurs. Work agents for my colleagues. Birthday agents for friends & family. Help me spread the good!

BREAKING: @claudeai just got a massive upgrade today and I'm so happy to be a part it. From now on, Claude Opus 4.6 can build Chrome Extensions for every Chromium-based browser. We just launched Shipper, a tool that lets Claude: ✅ Build complete Chrome Extensions ✅ Recreate existing Extensions ✅ Ensure multi-browser comatibility ✅ Write privacy policies ✅ Autofill entire Chrome Web Store listings Claude Opus 4.6 can do all the above in 1 simple prompt for as low as $0.11/extension... And it takes minutes, not hours! Open up Shipper and ask Claude to "create a free ad block extension" or "auto-invite 950 people weekly on linkedin". Since this is a very special launch, if you comment "shipper" you will get FREE credits :)

@IntuitMachine Hit the wall with CC+OpenClaw, OAuth gets revoked. Not renewing Max 20x, new setup: ChatGPT Pro and Codex for spawned workers & OpenRouter + Kimi K2.5 for permanent OpenClaw agents (unless ChatGPT OAuth works)

🧵 The OpenClaw trap nobody warned you about You finally set up OpenClaw (formerly known as ClawdBot and MoltBot) — the viral AI agent that actually *does* things (emails, calendar, WhatsApp, code, whatever). You plug in your shiny Claude Max subscription because “why not use the best?” And then… it just stops. Randomly. Over and over. You’re not broken. Anthropic is deliberately breaking it. 1/ Here’s the wild part: Your expensive “unlimited” Max plan is **explicitly not allowed** for tools like OpenClaw. Anthropic’s ToS (Section 3.7) has always said: no automated/non-human access outside their official apps or API. Early January 2026 they flipped the switch — OAuth fingerprinting, session kills, mass bans. Thousands of people (OpenClaw, OpenCode, Cline, Roo Code users) woke up suspended. I’ve seen the screenshots. People who dropped $100–200/mo on Max are now locked out entirely. 2/ So what actually works in OpenClaw right now? The models the community keeps coming back to (tested in real agent loops, not just chat): - Claude Sonnet 4 / 4.5 (via official API key) This is the cheat code. 90–95 % of Opus quality for agents, 5–10× cheaper, lightning fast, rock-solid tool calling. Most ex-Opus users say they literally can’t tell the difference in daily OpenClaw use. - GPT-4o / GPT-5.2 (native OpenAI support) Sometimes even better at certain coding/agent styles. Zero drama. - Gemini 1.5/3 Pro 1M+ context = god-tier when your agent needs to swallow whole codebases or long histories. - Moonshot Kimi (k2/k2.5) via OpenRouter Stupidly cheap + surprisingly sharp. A lot of heavy users live here now. 3/ Local/privacy gang: Qwen 2.5 72B or Llama 3.3 70B (Ollama / vLLM / ) Once you’re on a proper 70B+ with good tool-calling finetuning, OpenClaw feels magical and nothing ever phones home. 4/ Quick config that saves lives: In your OpenClaw settings: ```json "model": "anthropic/claude-sonnet-4-5", "fallback_models": ["openai/gpt-4o", "google/gemini-1.5-pro"] ``` (or just run `openclaw models set anthropic/claude-sonnet-4-5`) One API key. No bans. No random stops. Agent just… keeps working. 5/ The bigger picture: The “unlimited subscription” model was never built for real agents. It was built for humans who type 20 messages a day. OpenClaw (and the whole agent wave) exposed that in about 48 hours. So the people who are winning right now aren’t the ones paying the most for Claude Max. They’re the ones paying per token on Sonnet/GPT or running 70B locally — and their agents never sleep. 6/ Moral of the story: Your $200/mo subscription isn’t giving you the “best” agent. It’s giving you the most fragile one. Switch to API + Sonnet 4 (or one of the others above) and suddenly OpenClaw goes from “flaky toy” to “holy shit this is my new coworker.” 7/ Have you hit the Claude wall with OpenClaw? What model are you actually running right now that feels unstoppable? Drop your current stack below — best setups always win in the replies. (And if you’re still on Max… I’m sorry, brother. The lobsters are free now.) 🦞 End of thread. Go set up that Sonnet key. You’ll thank me in 10 minutes.

360 years. That is the collective Excel experience of my team of 30 people, in one room. I have personally used Excel for 20 years. Since the very beginning. We’ve spent decades "crushing it" when it comes to financial modeling. We knew every shortcut. Every nested formula. We thought we had reached the peak of efficiency. (They are better then me, just to admit) But I have something to tell you. The game just changed. In my opinion, we are witnessing the biggest innovation since Excel was first released. It’s not a new function or a Power BI update. It’s Claude. Specifically, Claude’s ability to build and manipulate Excel models. For 40 years, the "manual labor" was the tax we paid. Hardcoding formulas. Spending hours formatting cells. Manually linking sheets and building tables from scratch. That era is over. Claude can now handle the heavy lifting of building the structure, the logic, and the formatting in minutes. But here is the part that really surprised me: It actually understands accounting. It understands the relationship between a Balance Sheet and a Cash Flow statement. It understands how operating drivers flow into a P&L. We aren't replacing our expertise. We are finally liberating it. Instead of spending 80% of our time building the model, we spend 100% of our time analyzing the results. If you want this Prompt and Excel model, just drop a comment and I’ll send it to you. (Important: follow me so I can DM you!)

Codex team is working on a few experimental projects that are starting to shape up and I’m excited to share more about soon. But I’m curious, what would you like to see ship or improved by the end of the year other than better models?

@AbdoMobayad What is the product in practice? What do you deliver exactly? Is there a demo video or screenshot collection? I have no idea what I'd get for my money as there is no tangible product description, only a list of features.

Kiitos @VRmatkalla ❤️ Lapsi astui aamulla väärään junaan Leppävaarasta ja oli päätymässä suoraan Karjaalle. Teitte ylimääräisen pysähdyksen Kirkkonummella ja järjestitte, että takaisinpäin kulkeva juna jäi odottamaan häntä! Toivottavasti kiitokset tavoittavat henkilökunnan.

@lellubeth Fantasian puolelta sitten Belgarionin taru sarja (David Eddings) ja Maameren tarinat (Ursula K. Le Guin). Jos LOTR, GOT, Potterit, ja muu vastaava uppoaa, niin nämä menevät kuin kuuma veitsi voihin.

Alkaa vähän pitkästyttää twitter ja tiktokin selaaminen. Pitänee taas ottaa useammin kirja käteen. :) Mikä on paras lukemasi kirja?
