excited to be building @trypalette_ai with @leejosiey this summer @ycombinator!! looking forward to talking to people, learning, and building something meaningful side quest: explore every coffee shop nearby ☕️ if you're building or in the HR space, my dms are open :)

@lucyjcai @clairemao78 @tryinstance yess congrats on the launch!!!

We’re excited to launch Instance – a success detector for robot rollouts! Describe your task and drop in a dataset, and it judges success/fail on each rollout with detailed subtask captions– it’s more accurate than Claude Opus 4.8, at a fraction of the latency. This is just the first step toward our larger goal: an autonomous evaluation rig for robot learning. Today, evaluating a robot policy means humans have to watch the robot roll out, mark success, and reset the scene– we're automating that, starting with the success judge.

@clairemao78 @agupta @finbarr @ycombinator congrats this is so cool!!

we're excited to launch instance - automated evals for robot policies! incredibly grateful to @agupta, @finbarr, and @ycombinator for all the support :) ycombinator.com/launches/RPi-i…

which model did it best? ↖️ left: Veo 3.1, Google ↗️ top right: Seedance 2.0, ByteDance ↘️ bottom right: Kling 3.0 Pro, Kuaishou prompt: "A dimly lit kitchen late at night. A woman sits across the table from her estranged brother; her voice trembles as she says, 'You left when we needed you the most.' Her face moves through hurt, flashing anger, then a bittersweet half-smile as tears fall. Audio: trembling emotional dialogue, a quiet sob, a heavy tense silence, the low hum of a refrigerator, and soft rain tapping the window."
