for the past few weeks, I’ve been exploring painting with Fable 5.2 in code. one of the most common critiques I heard about Opus 5.5’s paintings was that it was only emulating real art. I thought that was fair, so i’ve been asking Fable 5.2 to develop personas—artists with some s…↗

We're in the process of renovating our home right now and Opus 5.5 did pretty much all of it Including making a cinematic trailer and magazine feature to get my fiancée on board↗

Weekend hack: HackerTube. I was annoyed with YouTube's recommendations so I had Claude filter down 43M comments over 20 years of HN to 6,454 videos that keep being recommended. *Significantly* better viewing experience, ~2 hours with Opus 5.5: hackertube.org - Excellent recs wit…↗

We’ve added a new way to access Claude on Google Cloud. You can now use the full Claude API from your Google Cloud account, including Claude Managed Agents, code execution, Opus 5.5 fast mode, and new features as they launch.↗

Education doesn’t have to be text and flat diagrams. So I’m building a 3D book about energy that students can play with: 10 lessons to predict, test and prove. Built with Opus 5.5 and Three.js. Try Lesson 1, Energy stores: everyday objects and where their energy is kept ↓↗

I wrote about the exponential curve of the last 30 months of AI development: oneusefulthing.org/p/30-months-on… And I asked Opus 5.5 to create the ultimate response to the test I use for all AI image generation models (make a picture of "an otter on a plane using wifi"), it made…↗

My new book, Co-Existence, is out today. It is a guide to how to live & work in a world where AI is sometimes, but not always, better than you. (And, for the release, I worked with Opus 5.5 to make a quite interesting experience for the book's website: co-existence.ai)↗

UI animations made with Opus 5.5 and @useclayzo↗

I asked Opus 5.5 to build an ancient Greek world as detailed as possible no assets were used! everything you see here is made with code↗

Six projects from the last few weeks that caught our attention: A wildfire analysis prototype that maps the fire’s spread over time and tracks hot spots, made with Opus 5.5.↗

Opus 5.5 mapped the entire coast to coast route across the USA for a clicker game I'm playing with. 5,285 km of real road, sampled every 10m from OpenStreetMap.↗

Haiku 5.5 is now available in the Claude Platform and Claude Code. On average, it costs around 75% less to run than Haiku 4.5. It pairs well with Opus 5.5 or Sonnet 5.5 as a subagent. Use it for high-volume, cost-sensitive tasks like summaries, compactions, or database queries.↗

This guy re-created all the adobe apps with opus-5.5, ported them to rust, and opensourced them something really cool is happening↗

I asked Opus 5.5 to make an interactive website companion for the latest @AcquiredFM Home Depot episode. It came out pretty nice! Water color illustrations all drawn by Claude, too: claude.ai/artifact/RdE6u… Episode here: acquired.fm/episodes/home-…↗

Automating Exceptional Product Tutorials at Scale with Devin You can automate pixel-perfect product tutorials with a cloud agent that has its own computer and records itself using your app the way a human would (like [Devin](devin.ai/)). This has technically been possible for a…↗

i’ve been teasing it all week, so here it is in time to ruin your weekend plans: Frontier Lab Tycoon every mechanic you might expect (swarm sandbox escapes, hyper-competitive model releases, safety audits, researchers Posting & getting dragged on Bird App, your new Decision Mode…↗

Industrial software doesn’t have to feel like industrial software Manage warehouses like you’re playing a strategy game Built with Opus 5.5↗

Opus 5.5 has been building animatics for me - draft versions of videos I'm about to film. It walks through the actual lessons, creates stills of what it thinks the learner should see, and narrates them with TTS. It's outrageously useful for planning videos (watch on 2x speed, i…↗

I asked Opus 5.5 to build a working computer from scratch. And holy fuck did it deliver. 277k logic gates in JS, an OS on top, and games on the OS. This isn't a mockup... it's a computer. Run it: somethingbig.ai/computer↗

Every time you let Opus 5.5 run a long task on its own, have it vibe-code a quick 𝗛𝗧𝗠𝗟 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱 like this first. Then give it 𝗮 𝘀𝘂𝗯𝗮𝗴𝗲𝗻𝘁 𝘁𝗵𝗮𝘁 𝗼𝗻𝗹𝘆 𝗯𝘂𝗶𝗹𝗱𝘀 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀: → Name it dashboard-builder, set its effort to medium, and preload…↗

one Opus 5.5 prompt, and now I run around a virtual office managing agents to work on github issues and merge conflicts↗

Using Claude Code: Spending your effort One of the best parts of our newest Claude models is how they respond to effort without breaking the prompt cache in Claude Code, but I’ve received a lot of questions on this from users. What is effort really and when do you use which effo…↗

I had high hopes for the new Opus release. It massively exceeded them. Opus 5.5 is an incredible model.↗

holy shit, opus 5.5 is kind of insane at animation. i didn't write a single line of code. it wrote the story, drew every frame, and made the music. no image assets at all, it's all JS. the story is called "small print": claude gets a pile of requests every day. it circles the hu…↗

opus 5.5, animated pixel art wizard, pure code prompt shared below 👇↗

Opus 5.5 is way, way, way better than Opus 5. Sorry about that model, please try this one.↗

I asked Opus 5.5 to try a bunch of redesigns of my personal website using my MAX sub, using workflows to iterate and critique. I was really pleased with how it hit the tone I was looking for. Then I asked it to make a trailer with all of its iterations.↗

I was invited to test Opus 5.5. The differences at the high end are hard to notice unless you're being ambitious. They reward ambition though. If you can't tell the difference here, or if you're intentionally micro-prompting a model, I think the fast models (composer, Gemini f…↗

Opus 5.5 is here! 🎉 It's honestly such a nice model to work with. Feels like Fable, but ~30% faster and ~40% cheaper per task than Opus 5. Go try it out!↗

opus 5.5 = personality of opus 4.6 that we all *desperately* wanted back + the intelligence & taste of fable 5.1. and a 25% usage bump! i honestly don’t really see a reason to use another model right now? s-tier release.↗
