UC Berkeley Researchers Release CUA-Lite, an Open Platform Unifying Sandboxes, Data, Evaluation and RL for Computer-Use Agents

UC Berkeley researchers have released CUA-Lite, an open platform for computer-use agents. Its Lite.OSWorld benchmark reproduces OSWorld tasks in a plain Docker container without nested virtualization, and scores match the VM version across 13 models. The platform covers 30k+ verifiable tasks and 15+ benchmarks, with datasets on Hugging Face. It also supports SFT and RL with per-model adapters and a shared data schema. The repository ships no explicit license, so terms should be verified before commercial use.
