Sometimes you see a graph that stops you in your tracks
October makes September look like a rounding error 👀
Never seen anything like this in my decade as an investor…

Human-robot collaboration 🟠👷
Now both the construction site and finished builds look like works of art.

Here's what this build looked like in Atrium. It's plain magical to write code that becomes a real building.
Being able to vibe code buildings is definitely not far off, if you build the right infrastructure and harness for it.
The model is the easy part
For anyone claiming robotics data is a solved problem or already commoditized:
- Confuses egocentric data with all types of robot-training data
- Has never tested a robotics model zero-shot
- Has never experienced the pain (and joy) of overfitting
- Has never deployed a policy on real hardware, not just in sim
- Has never tested generalization beyond the tasks seen in training or standard benchmarks like robodojo
Robotics data is far from solved.

Huh. So far they were always benchmaxxing. Scores looked great, but using the models were horrible. Maybe they are finally getting it?
our team uses gemini quite a bit now
whenever we have a tricky architectural problem, complex system design questions, or need to simplify something we ask for a gemini subagent
it's pretty good here. i don't see this talked about much

This looks like a vibe coded setup. But holy shit.
Last night an AI agent performed brain surgery on a mouse.
We gave it 19 gene therapy vectors in a spreadsheet, a mouse model of epilepsy, access to a motorize surgery rig with cameras and one goal: reduce seizures.
It picked the drug. It picked the brain region. It derived the coordinates from three papers. Then it drove the stereotaxic arms into the brain and injected 250 nanolitres while watching the entry site through the rig camera for bleeding.
A licensed vet gated every irreversible step and held a physical kill switch to stop the AI agent.
Thread on what it decided, what it saw, and the moment it refused to let me override it.
[Writing this on the spot out of excitement, but I've been 18hrs in front of my laptop coding and coordinating this, so keeping it brief and descriptive, more cohesive thoughts on this soon...]

This is when you know they won't ship anything useful any more. PMs and engineers are just bored at this point.

Our robots built this in the city of Almere: curved walls, different types of bricks and bonds, indented text.
Real world deployment, insane complexity, 100% of every brick done by our robots, with another 15 houses to come in the coming weeks.
People are being silly about this, LOC not being a good measure, stupid PRs etc. But truth is that engs have been shipping shit UIs, and designers are taking the reins - rightfully so.

1. Clearly sees the threat in Instinct etc.
2. Don't see how this will be truly useful without being deeply embedded into Slack etc
We’ve been humbled by the interest in Claude Duet, and are working hard to get people off the waitlist. In the meantime, a few thoughts based on DMs, emails, posts we’ve seen.
→ Who can use it: Pro and Max subscribers in the US, for now.
→ Where: You can use it on iOS, Android, and web once you get off the waitlist. Mac app is in the works.
→ Trust: We designed Claude Duet to be a partner you can trust. More on our safety, security, privacy approach in today’s blog post: claude.com/resources/article…
→ Use cases: We’re starting with work use cases, which is what a lot of people come to Claude for. Professionals, small business owners, founders, anyone juggling a lot. We’re opening the research preview to these segments first so we can co-build together. Over time, we'll support more use cases across work and life.
→ Context: Claude Duet already knows about everything you’ve been working on with Claude. Your chats, memory, projects, and more are available in Claude Duet the moment you open it.
→ Tasks: Tasks are at the center of the experience. Every task gets its own thread you can check in on and steer, so you can multi-task and hand off many things at once. Claude Duet also proactively suggests tasks it can take on, with your approval. We’re glad to see this primitive and dedicated tab resonating. More to come soon.
→ Proactive with judgment: Opus 5.5 is widely loved for complex real-world work and its natural communication style, and we’ve built around it for deep judgment. More work to be done here so it feels like a world-class teammate, coworker, chief of staff.
→ Channels: We went with one agent that works across your main chat and dedicated channels, so each area of work gets its own space. Small business owners and professionals are already using channels for customer support, marketing, bookkeeping, etc.
Starting next week, we’ll share more on how we built Claude Duet and how early testers are using it. We know usage limits and access outside the US are top of mind too, and are working on both. Please let us know what else we can improve - we're reading all your feedback.

AI is continuing to baffle me. It went from autocomplete, to files, to simple PRs, to now just give it super super ambitious stuff.
And it just does it.
The last 2mo have been crazy on how good it is.

This is insane
We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.
