With my custom architecture I now achieve on average 60% progress on my gearbox assembly task. The original average progress of pi0.5 base (after 10k fine tuning) was 14% . Trajectory of progress is looking good. Now have to reduce the cycle time of iterating on a base policy.

If you're a robotics company building on top of VLAs / other end-to-end learned AI models and want to train models reliable enough to deploy, ping me.

Robotic foundation models generalize well—but high inference latency limits real-time deployment. 🚀 AsyncVLA enables real-time control of large robotic models, even under network delays. Great collaboration with @CatGlossop ,@shahdhruv_ & @svlevine ! #EmbodiedAI #EdgeAI

Thank you for your interest! Yes, one rollout stage only. One major reason for the moderate recap performance is the policy pretraining. In Pi06*, recap method is applied in both policy pretraining and finetuning, upon a proprietary Pi06 architecture, whereas we can only re-implement it on a public open-pi05 checkpoint, which is not pretrained with action conditioning as additional input.

🧐Applying world models to improve real-world policy on challenging manipulation tasks used to be considered out of reach. 😌After sustained effort, we’re now seeing encouraging progress. 🚀Thrilled to introduce RISE: Self-Improving Robot Policy with Compositional World Model opendrivelab.com/kai0-rl/ arxiv.org/abs/2602.11075 RISE is, to our knowledge, the first work to use a world model as an effective learning environment for challenging real-world manipulation, enabling policy improvement on tasks that demand high dynamics, dexterity, and precision. Incredible teamwork with @lin_kunyang111 @francislee2020 @YueXiangyu @HaoZhao_AIRSUN @smch_1127

A new reward model called SARM —> Stage-Aware Reward Modeling for long-horizon robot manipulation is now in LeRobot! 🤗 Long-horizon, contact-rich manipulation (think folding a T-shirt) is messy. Demonstrations naturally include hesitations, corrections, and variable quality. Classic Behavior Cloning (BC) treats every frame equally, SARM takes a smarter approach. 🔎 How does it work? SARM uses a video-based reward model to predict: • the current task stage • fine-grained progress within that stage (0 → 1) This enables Reward-Aligned Behavior Cloning (RA-BC) by reweighing data based on progress improvement, allowing the model to distinguish trajectories that make progress from those that stall. Left image: successful rollout, learned progress smoothly increasing 0 → 1 Right image: unsuccessful rollout

My mom just sent me this video of my co-founder @shloke_patel and me pitching our mango business when we were 13. Now, in 50 days, we’ll be pitching at @ycombinator's Demo Day in SF. None of this would've been possible without our rockstar parents. Order some mangoes this summer at mangounited.com

My co-founder @shloke_patel and I have worked on every major project of our lives together. In high school, we sold 16,000 mangoes, planted 100,000 trees, and started a microbiology startup. He went to @Stanford, I went to @UCBerkeley, then we both dropped out to do @ycombinator and build Human Archive where we’re collecting and labeling aligned multimodal robotics datasets at scale. It’s been 20 years of him pissing me off and I genuinely don’t know how much longer I can take ts someone please find him a girl 😂😂

@RohanSeelan thank you, I’d recommend checking out the RTC implementation in LeRobot, that will get you a lot of the way there. I do plan to make my improvements open source soon

60hz! real time chunking on an so101 with LeRobot. Not looking too bad. Bit of jitter throughout but no mode switching across chunks

Our robot just got an upgrade. The eyes (camera), arms, and brain (controller) are now one compact portable unit — easy to move to any table, no perfect alignment needed, and fewer wires @7Xrobotics

🚀 Introducing X-VLA ; LeRobot’s new soft-prompted Vision-Language-Action model. X-VLA is built to scale across many embodiments: different robots, cameras, action spaces, and environments, all handled by one unified transformer backbone. - Generalist across robots (Franka, WidowX, Agibot, sim + real) - Soft-prompt domain IDs let the model adapt to new hardware with tiny learnable embeddings - Flow-matching + transformer core for smooth, continuous 50 Hz control - Pretrained on a mixed-embodiment dataset spanning 7+ platforms and diverse tasks - Fine-tune on any dataset using one of the 6 checkpoints we provide out of the box.
