Raspberry picking was not on the list. Back I go.

my heart and stomach are so full of the freshest raspberries in the bay area

@bazashc Have you ever read it??? It’s 100% not a children’s book and whoever says that is lying to you. Not only is the vernacular dated and elaborate but the sentence structure and lengthy writing is often hard to get your head around as an adult. Love that book! but it’s not for kids

My manager!!

Sad.

Alright who’s up on the Connor revenge tour? @BlessedMMA?

Imagine being from a place, any place at all, and thinking everybody from another place, is, the same.

This morning at ICML 2026, I'll be speaking at the Workshop on Decision-Making from Offline Datasets.

Come to ASEM Ballroom 203 at 8:15 am KST!

I'll talk about foundations of data-driven decision making, from design via model-based optimization to offline RL

[Chelsea Finn @chelseabfinn]

I'm giving a talk on how we can move beyond the scalar reward bottleneck for both robotics & LLMs.

ICML RLxF workshop tomorrow at 1:30 pm.

[Chelsea Finn @chelseabfinn]

I'm giving a talk tomorrow at ICML on emergent physical generalization, including π0.7 🤖

3:15 pm @ SCALE workshop in Ballroom 201

Elite new in-game promotion just dropped.

True perfection, no notes.

[Chelsea Finn @chelseabfinn]

We’ve been approaching reward supervision for robots the wrong way.

I think freeform preferences are part of the answer.

A short 🧵

[Anna Walling @annawalling]

we’re hiring for three ops roles at @physical_int each focused on a different part of scaling robot data collection:

Product Manager
Strategic Projects Lead
Data Annotation Lead

shoot me a note if one sounds like a fit 😎 https://t.co/Wdfl2mcUkL

[Blake Williams @BlakeWilliamsSF]

Can only thank God I don’t have to hear the English commentators talk about that.

[Blake Williams @BlakeWilliamsSF]

Sounds like a guy who’s never hit a parlay at the buzzer.

[Nick Huber @sweatystartup]

This is a catastrophe for our culture and our country.

[Blake Williams @BlakeWilliamsSF]

Fucking massive if true.

This vial contains a new drug called PAC-832, which I recently invented to treat Alzheimer’s disease. It is the world’s first selective GalR1 antagonist.

I designed and synthesized PAC-832 in a chemistry lab I built in my garage. (1/16)

[Blake Williams @BlakeWilliamsSF]

I have absolutely zero need for this, and I must have one immediately.

NEW: Apple and Audi alumni just unveiled a $25,000 open-air electric neighborhood vehicle.

Amble One is a street-legal EV built for short local trips, with no doors, fewer screens, and a modular design inspired by the 1960s lunar rover.

• Goes up to 40 mph with 60+ miles of range
• Weighs under 1,000 lbs with a 5-hour home charge
• Rear seats fold flat for cargo, surfboards, or gear
• Built-in mounts let you add baskets, straps, mirrors, and cargo accessories
• Already has 500+ vehicles committed by resorts

Reservations are open now for 2028 deliveries.

[Blake Williams @BlakeWilliamsSF]

A+

[Bojan Tunguz @tunguz]

What exactly did you guys think "permanent underclass" was gonna look like? Having access to all the same models and resources as the insider elite? LOL

[Paul Snively @JustDeezGuy]

Phil Williams. My boss’ boss at Apple. Surfer dude, feet on his desk. We guys asked each other over lunch “What does Phil do all day?”

Then Phil left.

“Oh.”

I’m sorry, Phil.

LLM RL optimizes for sequential reasoning

We also optimize over the reasoning strategy, incl parallel trains of thought, aggregation of parallel traces, & sequential reasoning

This allows the model to better explore & allocate compute at test time

[Sergey Levine @svlevine]

We can learn a model that provides shaped "process rewards" for robotic RL, that evolves automatically as the policy gets better. This improves performance on benchmarks, and works in the real world! Some fun new work with Raymond Tsao & @ajwagenmaker
