Humanoid robotics is hitting a data wall. Teleop and mocap took us far, but they don’t scale to every object, terrain, and behavior.

We’re releasing GRAIL: https://t.co/LxTKtMPtw0 — a fully digital pipeline for generating loco-manipulation data before the robot moves. 🧵(1/8)

How do you teach a humanoid to assist another person in close-contact? 🤖
The hard part: the two bodies are physically coupled — helper & helped continuously shape each other's motion.
Neither can be solved alone.

Introducing GPT-Realtime-2 in the API: our most intelligent voice model yet, bringing GPT-5-class reasoning to voice agents.

Voice agents are now real-time collaborators that can listen, reason, and solve complex problems as conversations unfold.

Now available in the API alongside streaming models GPT-Realtime-Translate and GPT-Realtime-Whisper — a new set of audio capabilities for the next generation of voice interfaces.

What is missing to bring real-time motion research into AAA games and real-world robotics?

We present MotionBricks, a step toward bridging this gap with two key components:
- a single generative latent motion backbone covering 350,000+ motion skills, running at 15,000 FPS with 2 ms latency and substantially improved quality and reliability.
- a unified smart primitive interface for locomotion, object / scene interaction, with fine-grained control over generated behaviors.

Can we build a standalone, modular, and reusable naturalness reward for training motor controllers?

#SMP is a step toward that vision. Once SMP has been trained on a motion dataset, the priors can be reused to train new controllers to perform diverse tasks while adhering to the behaviors in the dataset, without original dataset or retraining.

🔥 Excited to share our latest work, SMP: Score-Matching Motion Priors, accepted to @siggraph

I’m so tired of writing rebuttals to this kind of “lack of novelty” review: “This paper trivially combines A, B, and C, so the algorithmic novelty is limited.”

Technically, most (if not all) robotics papers are convex combinations of existing ideas.

I still deeply appreciate A+B+C papers—especially when they deliver:

- New capabilities: the “trivial combination” unlocks behaviors we simply couldn’t achieve before

- Sensible & organic design: A+B+C is clearly the right composition—not some arbitrary A′+B+C′

- Nontrivial interactions: careful analysis of the dynamics, coupling, or failure modes between A, B, C

- Rehabilitating old ideas: A was dismissed for years, but paired with modern B/C, it suddenly works—and teaches us why

- System-level & "interface" insight: the contribution is not any single piece, but how the pieces talk to each other

- Scaling laws or regimes: identifying when/why A+B+C works (and when it doesn’t)

- Engineering clarity: making something actually work robustly in the real world is not “trivial”

- New problem formulations: sometimes the real novelty is in the reformulation—only under this view does A+B+C make sense.

Maybe worth keeping these in mind when reviewing the next A+B+C paper : )

A nice little quality-of-life update, MimicKit now supports video logging. You can monitor the agent's behaviors during training on WandB and Tensorboard:

We also added an implementation of Lipschitz-Constrained Policies for training smooth controllers.

Peeling a potato is trivial -- until you try to make a robot do it with a knife.

This is actually one of the hardest problems in manipulation: contact-rich, force-sensitive, and success is subjective.

We taught a robot arm to peel with >90% success :D

[Xialin He @Xialin_He]

Real-world loco-manipulation demands more than replaying fixed reference motions.

We argue that true autonomy requires two capabilities:
1️⃣ flexibly leveraging whatever signals are available — dense references, partial cues, state estimates, or egocentric perception
2️⃣ remaining capable when any of these signals are missing or unreliable
We introduce ULTRA — an all-in-one controller for unified humanoid loco-manipulation 🤖
It supports:
• general reference tracking
• sparse goal following
• execution with motion capture
• execution with egocentric perception

🚀 Introducing CHIP: Adaptive Compliance for Humanoid Control through Hindsight Perturbation!

Current humanoids face a trade-off: they are either Agile & Stiff OR Slow & Soft.

CHIP breaks this barrier. We enable on-the-fly switching between Compliant (wiping 🧼, collaborative holding 📦) and Stiff (lifting dumbbells 🏋️, opening doors 🚪💪) behaviors—all while maintaining agile skills like running! 🏃💨
