Follow Gemini 4 Argon's report, I implemented their robotics harness.
Gemini did a zero-shot bimanual handover. Now open source ๐ค๐

โHow can humanoids learn by watching humans?
Naive retargeting can lose crucial contacts: like bracing a hand on a table while bending to pick an object off the floor.
๐ Introducing VICAR: preserve key contacts from human videos, practice in simulation, deploy on hardware

New surprising result:
We trained AI recursively on its own safe generations, while giving it a benign cue. Models became increasingly misaligned over time, giving advice on how to do harm and build biological weapons.
We call this Progressive Misalignment. ๐งต๐

Last year I trained the advantage-conditioned VLA for ฯ*0.6 during my internship @physical_int. Now, I have a much improved recipe.

Seeing is an act in itself. We look at what matters, and so should robots!
EyeRobot 2.0 does this with gaze, enabling precise manipulation without wrist cameras. Key for tool use, where the tool can block a wrist camera!
Co-led by @justkerrding who'll be on the job market! Hire him :)
Almost all bimanual robots include wrist cameras. They add bulk, cost, and complexity, but are critical for performance. Are they really needed?
Excited to finally share EyeRobot 2.0, where we use active gaze from an ego stereo camera instead ๐งต (with @kushtimusprime)

1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness.

Can you sample a robot policy the way you sample an image? ๐ฒ
No RL run. No reward. No fine-tuning.
We train a diffusion model on the ๐๐ฒ๐ถ๐ด๐ต๐๐ of thousands of RL policy networks, then sample brand-new ones that walk ๐ถ, dance ๐บ, and spin-kick ๐ฆต on a real Unitree G1 ๐ค
The best part? The ๐๐ฒ๐ถ๐ด๐ต๐๐ have a secret ๐ Every network, no matter the motion, pays the most attention to the hips and waist โ embodiment comes first; motion comes second. ๐ฆพ

As agents perform AutoResearch they get fixated on their old ideas and do only incremental innovations. We introduce a simple context management trick that forces the agents to forget everything they have done except the best solution they have found so far.
This simple modification in context management allows the agents to get out of their idea basins and come up with more novel solutions.
Closely related to the work 'Fork and Flush' and 'Idea-basins' that @DimitrisPapail posted a few days ago.

Gemini-4 Argon shows a large improvement in robotics understanding on RoboVista.
It reaches 81.9%, beats GPT-6 Astra and Claude Fable 5.1 in our evaluation with lowest eval cost. Compared with Gemini 3 Flash, it improves across every robotics domain. Example VQA๐
๐คHow well do today's VLMs actually understand real-world robotics? ๐
Excited to share RoboVista at #RSS2026 โ a systematic evaluation and benchmark for VLMs across diverse, real-world robot applications. Website, dataset and paper: berkeleyautomation.github.ioโฆ

Slow evaluations are a major bottleneck in AI-driven systems optimization. DuoDiscover addresses this by having agents generate fast evaluation proxies (โyardsticksโ) alongside the code. The result: a 2.68ร speedup for TPU kernels and a 1.92ร speedup for vLLM serving!

So excited to release DuoDiscover! I worked on it over the summer for my internship @Google with some awesome collaborators. We got some amazing results on open source benchmarks and internal tasks!
Was super fun working closely with @shagarw21 @dilarafsoylu @MikeHeddes @RuiMeng_ @VioletNPeng and thanks to @chunliang_tw for being the most amazing manager ever!!
Such a cool collaboration between @googlecloud @berkeley_ai @StanfordAILab
AI is cracking math problems. What's holding it back in engineering?
The cost of evaluation. Agents can generate ideas in seconds, but testing them can take hours or days.

Cool results making auto-research / AI-based optimization better by having agents forget! Turns out that just running an agent for a long time can lock it into small steps in the same direction.

Autoresearch with coding agents can now run for days on a single problem, but we've seen an increasing number of cases where they stop improving early. We address this issue with a simple idea: forgetting.

Pushing TPUs to their limits. FLAT hits 90% of peak HBM bandwidth (1.48 TB/s) and delivers large training speedups for Mamba-2 and GLA over standard H100 baselines. Great deep dive into kernel-level hardware optimization!
