Beipo Open-Sources NorthCUA Computer-Use Agent Suite and Harness Execution Framework
北坡开源 NorthCUA 全家桶！多项开源 SOTA，模型、Harness、123 页技术报告齐发
Beipo's NorthCUA team has open-sourced its full suite of computer-use agents, including three model tiers (Nano, Mini, and Pro) ranging from 9B to 397B parameters, the Harness execution framework, and a 123-page technical report. NorthCUA-Pro achieved state-of-the-art results among open-source models on benchmarks such as OSWorld-Verified. The technical architecture combines broad-coverage GUI pre-training, long-horizon SFT, and joint desktop-web reinforcement learning, while introducing an "Ultrafast" mechanism that uses a lightweight selection head to reduce interface action latency.
The original paper provides a complete framework for computer-use agents spanning long-horizon task construction to staged post-training, offering a valuable reference for closed-loop designs in long context handling and verification mechanisms.
