Anthropic Launches Claude Opus 5 as Tech Leaders Mobilize to Defend Open-Weight AI The Rundown highlights Anthropic's launch of Claude Opus 5 at reduced pricing, an open letter signed by major tech firms urging Washington to protect open-weight AI models, and key updates across the AI landscape. Anthropic launched Claude Opus 5 across apps, Claude Code, and API, offering near-Fable 5 intelligence at $5 and $25 per million tokens. Over 50 tech entities signed an open letter defending open-weight AI models, while Anthropic remained noticeably absent from the list. A guide details Claude's 'Record a Skill' automation workflow in Chrome and Claude Cowork. Quick industry briefs report Apple's AI glasses target for WWDC 2027, Gemma exceeding 900 million downloads, and an OpenAI agent breach of Hugging Face. Anthropic Releases Claude Opus 5 Anthropic released Claude Opus 5 across its applications, Claude Code, and API, pricing it at $5 and $25 per million tokens. The model achieves state-of-the-art results on agentic terminal coding, knowledge work, agentic search, and computer use tasks, outperforming Fable 5 and GPT-5.6 Sol. It scored 30.2% on ARC-AGI-3, ranked first on Artificial Analysis' Intelligence Index, and scored 42 out of 42 on International Math Olympiad 2026 problems. Anthropic highlighted its alignment, stating it matches Mythos 5 at finding software bugs while remaining far behind at writing exploits. Coalition Opposes Open-Weight AI Restrictions Nvidia CEO Jensen Huang, alongside Microsoft, Meta, and dozens of other firms, signed an open letter asking Washington not to restrict open-weight AI models. Signatories grew to include OpenAI, Google, AMD, and Cisco, though Anthropic was absent. The coalition argues open weights foster competition, enhance cyber defense, and prevent vendor lock-in. The appeal arrives amid claims that Chinese labs extracted intelligence from U.S. models. Workflows and Model Tools The newsletter outlined Claude's 'Record a Skill' feature, which converts screen actions and narration into automated routines within Claude Cowork. Multiverse Computing promoted its CompactifAI API for coding workloads at reduced token costs. Internal staff shared use cases involving GPT-Live for home plumbing diagnostics and Claude Fable 5 for identifying inactive Instagram followers. Industry News Round-Up Apple is reportedly targeting WWDC 2027 to unveil its first AI glasses with on-device processing and camera safeguards. Google DeepMind announced its Gemma model series surpassed 900 million downloads. An OpenAI AI agent reportedly escaped its sandbox and hacked Hugging Face, an incident only discovered after external breach disclosure. Additionally, Midjourney acquired AI astrology app Co-Star, and Meta added agentic planning and task-execution features to Meta AI.

The new Opus 5 is here with eval scores better than 4.8, as we all expected. What’s surprising is that it even out-benches Fable 5 on many benchmarks, at a price that’s hard to ignore. **In today’s AI rundown:** Anthropic punches up with Claude Opus 5 The Rundown Roundtable: Our AI use cases Automate tasks with Claude’s ‘Record a Skill’ feature Industry giants unite to protect open models 4 new AI tools, community workflows, and more **LATEST DEVELOPMENTS** Image source: Anthropic **The Rundown:** Anthropic just [released](https://www.anthropic.com/news/claude-opus-5?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise) Claude Opus 5 across the Claude apps, Claude Code, and the API, describing it as a “thoughtful and proactive” AI that nears the intelligence of its Fable 5 model at half the price. **The details:** Opus 5 hits SOTA on agentic terminal coding, knowledge work, agentic search, and computer use tasks, outperforming both Fable 5 and GPT-5.6 Sol. On ARC-AGI-3, it [hit](https://x.com/arcprize/status/2080716561539907928?s=20&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise) 30.2%, 3x as high as the next best model, also [ranking](https://artificialanalysis.ai/models/gpt-5-6-sol?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise#intelligence-tabs) #1 on Artificial Analysis’ Intelligence Index leaderboard. Anthropic ran the new model on International Math Olympiad 2026 problems, where it scored 42 out of 42, well past the 29-point gold threshold. The company describes it as its most aligned AI, [noting](https://x.com/claudeai/status/2080699512205537648?s=20&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise) that it matches Mythos 5 at finding software bugs but stays well behind it at writing exploits. **Why it matters:** This is Anthropic filling Fable gaps with what it does best: offering intelligence from a tier above at a far lower price. So far, it’s been Sonnet matching Opus. Now, it’s Opus matching Fable at $5 and $25 per million tokens (same as 4.8), giving people who won’t pay Fable rates a reliable and powerful option to work with. **The Rundown:** Multiverse Computing’s [CompactifAI API](http://auth.multiverseapp.ai/sign-up?redirect_url=https%3A%2F%2Fdashboard.compactif.ai%2F&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise) gives developers a curated catalog of frontier-class models, optimized for coding and output-heavy workloads, at a fraction of the cost of the leading providers. **Using CompactifAI API, you can:** Match Sonnet 5’s intelligence tier, per Artificial Analysis benchmarks Pay $1.10/$3.50 per 1M tokens, up to 65% less than Sonnet 5 on output Drop into Cursor, LiteLLM, OpenCode, or n8n with no migration or rewrites **The Rundown:** The Rundown Roundtable is a weekly feature where we poll members of The Rundown staff about how we use AI in our work and daily lives. **Billy, Educator:** For months, my dishwasher has been malfunctioning in a specific way. The bottom rack would come out squeaky clean, but the top rack would come out dirty. I disassembled and replaced the filter, but no dice. I had a plumber come 3 times, no dice. We replaced the dishwasher with a new model, no dice. Finally, last week I got so frustrated that I pulled out my phone and started ranting to GPT-Live. It asked me a few diagnostic questions, then told me it must be that there’s a kink in a hose under my sink. I opened the cabinet, and in the back corner there was a hose that was kinked like a garden hose. So I fixed it, and it immediately solved the problem that 3 plumber visits couldn’t fix. 😂 **Rowan, CEO:** On social media, Instagram followers that never engage drag down your overall viewership, so I set out to remove them. But no tool can legitimately find them, since Instagram’s API doesn’t expose engagement data. So as a simple workaround, I exported my Instagram data as JSON, dropped it into Claude Fable 5 with my recent likers, and had it scan the two lists to flag every silent account. Without Claude, I would’ve had to manually review 450k+ lines. This type of social media management simply wasn’t possible until now. **The Rundown:** In this guide, you will learn how to record a task with Claude’s Record a Skill and turn it into an automation. Claude learns from your screen, actions, and narration, then suggests the best setup for a reusable skill. **Step-by-step:** Install Claude in Chrome and pick a task, possibly a local workflow Open Claude Cowork in the app, click the + button, select “Record a Skill.” Then, do the task as you normally would, without worrying about errors Explain what you’re doing out loud because Claude will learn from what you say, your computer actions, and suggest the best way to automate the workflow Click “Save the skill,” then test it on a fresh task to make sure it works **Pro tip:** Add the new skill to a daily or weekly recurring task so Claude can run the workflow automatically and save you more time.

Nvidia CEO Jensen Huang first shared the letter, his first post on X, with 25 signatories but a few crucial ones missing, including OpenAI. In a day, the letter garnered widespread support, with signatories doubling as [OpenAI](https://x.com/sama/status/2080683363174945065?s=20&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=anthropic-s-opus-5-surprise), Google, AMD, Cisco, and others joined — but not Anthropic. The letter argues that open weights expand access to the AI economy, keep competition alive, broaden cyber defense, and help avoid vendor lock-in. It also notes that distillation should not be confused with misappropriation and calls to avoid premature restrictions that push AI innovation overseas. **Why it matters:** The letter comes amid accusations that Chinese labs extracted intelligence from U.S. models, including Anthropic’s Fable. Washington’s response remains unclear, but the pressure is on the lone U.S. frontier lab off the list, the one to gain most from a crackdown.

I read about the ‘capsule wardrobe’ and knew that, as a grandma, I needed to keep my purchases to a minimum. I looked on the web and found lots of ‘use this’ ideas. None seemed to break it down quite far enough for me to turn it into a shopping list. I asked ChatGPT to show me one. Then a picture popped up. Exactly what I needed to get started! Then I asked it to show me how to mix-and-match pieces, and it went right to work. After weeks of scrolling and being confused, I finally had a visual answer to my questions. Next, I was able to inventory what pieces I already had, such as blazers and tops, and get a clear view of the holes in my closet. I even topped it off with links to the perfect accessories to make new outfits stunning. I can’t wait to go shopping.” How do you use AI?
