RL Data ScalingBinfeng Xu
Agent Research · NVIDIA
I’m a researcher at Nvidia, co-optimizing RL systems for language agents – infra, algorithms, harness and data/env.
I built Polar, the first open RL framework bridging post-training and harness engineering. To scale RL data in the open, Skill2Env synthesizes environments with public Agent Skills. FlashREINFORCE presents an elegant RL recipe to reduce instability and false credit-assignment in long, async RL.
See below for recent publications on terminal/computer-use agent, post-training infrastructure and algorithm, vertical harness (eg. autoresearch) and continual learning.

I play all games by Hidetaka Miyazaki. I enjoy art, training large neural nets and petting cats.
