Making models smarter @ Anthropic, formerly CEO and Co-Founder @ Vercept (acquired by Anthropic), Climber on the weekends. Opinions are my own.

Seattle, WA
This is a long post, mainly because I have a lot to say, but in case you are too busy: TLDR: @Vercept_ai is joining @AnthropicAI! We shared a mission, so we joined forces to accelerate it into reality. Couldn't be more excited! Why Vercept was started In 2024, AI coding tools were already becoming magical for developers, but other industries were ages behind. It felt insane that when my mom had IT issues, I still had to hop on a call and walk her through it step by step. Insane that sending a simple email took so many clicks. That's why we started @Vercept_ai : Build something that acts for users instead of telling them how to do it. Two goals: 1) help people do tasks they didn't know how to do, and 2) handle the zero-brainpower tasks so people spend more time on creative work. As simple as scheduling meetings, as complex as reconciling messy financials before tax season. Ultimate goal was to have people spend less time behind screens and more time walking in nature. (Very Pacific Northwest mission 😁) The ride The journey of building an AI native company in this day and age was wild. Going from researcher to founder meant trading “reviewer number 2” for business partners and users, but surprisingly a lot of the same paradigms applied. Come up with a hypothesis, design an experiment, analyze user behavior, change the model and product based on the findings, wash, rinse and repeat. There are some differences though. The pace and the adrenaline. Lows are low, highs are high. We were constantly being challenged and learned at a pace we had never learned before. NEVER! If you are an adrenaline junkie like we are, it's a blast. The joy of the startup adrenaline rush is truly underrated. Why Anthropic We raised more than $50M, had a comfortable runway and a successful product, were building full steam with a small team, and were truly enjoying every minute of it. But that's when the opportunity came to join forces with Anthropic. We already knew how great Anthropic was at building models and we admired their mission, but then we learned more about the vision. We went on hours of walks, had long conversations, talked to members across different orgs, and learned more about Anthropic's vision and commitment to core beliefs which were very similar to ours. The more we talked, the more we realized we had been working on the same mission but from complementary perspectives. We realized that joining forces meant we could build something much much bigger together. And beyond the mission, I am now a big believer that Anthropic's real moat isn't its best model. It's the people. Incredibly talented folks who genuinely care about mission and real impact over hype. A zero-ego culture obsessed with building something meaningful. The choices were clear: we could build independently and work toward the same vision as two separate versions of it, or join forces with an incredible team and accelerate that vision into reality. The decision became an easy choice. What's next for our mission Mission continues, just got a bigger stage and an expanded team. The goal is still to expand AI beyond just a chatbot, to enable non-technical users to leverage it just as much as technical ones. We're just getting started. It takes a village This journey wouldn't have happened without the people who made it what it was. First and foremost, my cofounders @LucaWeihs and @inkynumbers . Best people I could've wished for as cofounders. We never once got into an argument, always had communicative discussions and as a cherry on top shared the same sense of humor! I feel blessed and grateful to have these two in my life. Thankful to our team for trusting in the three of us and showing up day and night. Grateful for @sethbannon , our board member, lead investor, great mentor and the person whose energy is so infectious that whenever we were having a down moment we would say "channel your inner @fiftyyears energy!" And to our wonderful investors and supporters: @chrija and @PointNineCap , Yifan and Jacob and @ai2incubator , and @mattmcilwain and Ted Kummert from @MadronaVentures . Couldn't have done this without you. Onward 🐜

What are specific requests in Claude Computer/Browser Use that have failed for you? We want to fix. An example for me is: "pay my barber $40 through my personal paypal" (where paypal is logged into my 2nd chrome profile, I'm logged out but password is saved)

I will get over making videos with Claude one day!!! Hopefully! I asked Opus 5.5 to: "learn everything it could about me online with computer use, then make a funny video." It found my hobbies, my work, even read my papers lol. There are some Easter eggs in there too. This is so so so cute! (It comes up a bit braggy I do apologize on that but I wanted to just post the 1shot)

Opus 5.5 is good in ways that surprises me every day! It's incredible how big of a jump in multimodal it is! Got Opus 5.5 to move my furniture into a house on Zillow 🏡 I gave it a video of my home and the Zillow link for a home. My prompts: 1. "Learn the furniture I have from this video, then make a 3D version of this house and furnish it with my furniture. Make it photorealistic" 2. "Now make me a walkthrough video and a 3D version I can interact with" 3. "Make a video of this entire session showing the steps you took" Watch till the end for the walkthrough of 3D scene 😅 (Disclaimer: I'm not actually buying this house, it's just a random zillow link!)

Since I am obsessed with painting these days I got Opus 5.5 to replicate Mona Lisa. This was my prompt: "can you search for the picture of Mona Lisa, then replicate it using mouse movement and brushes in JS paint using chrome?" It took 20 minutes for the drawing part using Cowork + Claude in Chrome. After it was done I asked: "Ok now can you make a video of exactly what you just did? Showing every mouse movement and changes?" Result is the video you see! :D More details in thread 🧵

Lol! Sure we had some models that weren't great to interact with! But capabilities were there 😂 Opus 5 wasn't that bad was it? It was just bad at writing 😁
I'm sorry I had to make this meme Let me know if you agree 😅

This looks like a video of the Golden Gate Bridge, but it's actually entirely generated using code by @claudeai Opus 5.5. From my testing, I think Opus is just as good at building 3D scenes as Astra. 📌 Watch my latest video to see how Opus and Astra compare on this scene and more: piped.video/UhBqorWNwlU
With Opus 5.5, I think @claudeai is finally back. Here’s my new video with my honest take and live demos on: → Can Opus rival Astra at building 3D scenes like the Golden Gate Bridge? → How does Opus handle computer use, UX design, and video editing? → Does it finally feel good to talk to again? This is the most excited I’ve been about Opus since 4.6. Watch my video to understand why: piped.video/UhBqorWNwlU

This is probably the coolest model release we have had since we have joined Anthropic! The visual capabilities of this one is 👨‍🍳🤌
Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

Bear with us, it will have rough edges at first but we will get better!
Claude Cowork and chat are merging into one Claude. Ask a quick question or hand over a report, and Claude takes it from there, even after you close your laptop. If something's unclear, Claude asks—you keep the final say. Rolling out to Pro and Max over the next few weeks.

Claude is getting so good at making videos!!!
we rebuilt Claude Design within Claude.ai and Claude Code from the ground up! it works everywhere: CLI, Desktop, web, Tag. Slides and Design are now separate — they're better that way! check out this video Claude made for the occasion...

Using Claude in Chrome product. Prompt: replicate this image (my profile picture) in jspaint, use brushes to replicate it as closely as possible. I want you to use brushes and clicking. Do not use javascript tool, but the final result has to be very close to this image. DO NOT CHEAT 1. I specified the do not use javascript tool because otherwise it uses javascript and it is faster but it seems like people cared more about clicking :D 2. The task took 45 minutes, but I don't think it's that much slower than competitors 😄 3. Prompt is important. (See thread)

If you don't tell Claude you want the exact replicate it will use its creative power and makes images that are different (this image is from the exact same setup but with the prompt "paint this image in paint" instead of the prompt above). We need to work on Claude being better at understanding the vague prompts, that I agree with!

Computer use in the Claude Code desktop app now runs in the background. Claude works in the apps you've allowed it to while you keep working. It's already on if you've used computer use before, or turn it on in Settings > General. In beta on Pro and Max, macOS only.

Claude can now use your computer in the background in Claude Cowork and Claude Code. Give it something to do on your desktop and Claude clicks, types, and opens apps just like you would, while you work on something else.

Happy launch day! Fable 5.1 is very capable but it is also really awesome in visual taste! I love the visuals it makes!
We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work.

Claude now has its own built-in browser in Cowork. When your task involves a website, a browser opens in Cowork's side panel, and Claude navigates, fills forms, and finishes the job.

San Francisco! This is your chance to meet the amazing Christoph! Don't miss it! I was lucky enough to catch him in his last 6 months SF visit and I consider myself very lucky and fortunate!
Thrilled to be back in the Bay Area for the next 6 months! “Let me know who I should meet”, as they say. :) PS: Still no shiny office on Sand Hill Road, but the temporary P9 US HQ is slowly taking shape.
