Reflecting on my @anduriltech journey feels surreal. Six years of relentless problem-solving, camaraderie, and defining moments. Grateful and proud to be able to share these stories for the first time.

- As some of you may know, several months back I transitioned from leading Engineering @anduriltech, to starting a company with a talented team of world experts in robotics with the goal of tackling robot learning at scale at @physical_int Today I'm excited to share our first step
- We asked π₀.₅ — trained mostly on data from other robots and the web — to “load the dishes” and “make the bed” in homes it had never seen. It parsed the instructions, planned, and executed end‑to‑end. This isn’t just a research milestone; it’s a real step toward
00:00 - Replying to @ashleevanceThanks for the kind words, @ashleevance! It's certainly hard to find an opportunity that properly follows our incredible journey at @anduriltech, but co-founding @physical_int with this team is something truly special. Can't wait for you to see what we have in store!
- Can't promise that no servos were harmed...excited to share what we've been up to soon!

- Introducing "Hi Robot": we developed a way to let robots 'think through' complex tasks, breaking them into basic steps, modifying tasks on the fly, and adapting to user feedback. A major step in robot intelligence. Great work @lucy_x_shi and team at @physical_int! Learn more
- @anduriltech is proving that with the right team and business model, a seven-year-old company can go toe-to-toe with the entrenched primes. I couldn't be more proud of our team and what we've achieved starting from a small hanger next to SNA to building a defense tech companyAnduril has secured $1.5B in Series F funding to hyperscale defense manufacturing. Introducing Arsenal-1, a 5M+ sq ft state-of-the-art facility to produce autonomous weapons systems. Learn more: anduril.com/article/anduri…
- The metaphor of a rock tumbler shaping rough stones into beautifully polished rocks reminds me of my time at @Tesla, where we had very passionate teams shaping great ideas into products, borne out of that friction. Building great products with high performing teams is largelyPrecisely
- Excited for the team to share FAST - our new robot action tokenizer - pulling off 5x improvements in VLA training speed. Congrats @KarlPertsch and team @physical_intThere are great tokenizers for text and images, but existing action tokenizers don’t work well for dexterous, high-frequency control. We’re excited to release (and open-source) FAST, an efficient tokenizer for robot actions. With FAST, we can train dexterous generalist policies
- π₀ is now open source. Model, weights, fine-tuned checkpoints—ready for you to build on. → GitHub: github.com/Physical-Intel… → Blog: pi.website/blog/openpiMany of you asked for code & weights for π₀, we are happy to announce that we are releasing π₀ and pre-trained checkpoints in our new openpi repository! We tested the model on a few public robots, and we include code for you to fine-tune it yourself.
