Astra's perception got much better: mostly scale plus pretraining encoder wins

willdepue · x · 2026-09-07

In the ongoing discussion on Astra's 3D modeling leap, willdepue notes the model's perception improved dramatically — "probably mostly just scale, but I'm sure some pretraining arch/encoder win." Astra "can see really well and this surely helps." Combined with his earlier take, he attributes the overall jump largely to better-targeted RL environments.
