NorthCUA-Pro

NorthCUA-Pro is the largest computer-use model in the NorthCUA family: a ~397B-total / 17B-active MoE on Qwen3.5 that turns screenshots, interaction history and instructions into reasoning, replies and tool calls for desktop or browser runtimes. Siblings include NorthCUA-Nano (9B dense) and NorthCUA-Mini (35B-A3B).

It is designed to run with the official NorthCUA Harness under a strict normalized_1000 GUI coordinate contract. Weights/docs are Apache-2.0 on Hugging Face (china-beipo/NorthCUA-Pro / beipo-ai/NorthCUA-Pro); tech report arXiv:2611.02102. Open-source and X coverage spiked around November 3, 2026.

Highlights

• Job: desktop/web automation, not chat-only.
• Training story: Experience Flywheel + Harness long trajectories + staged SFT/RL on large GUI corpora.
• Reported scores: ScreenSpot-Pro 93.30%; leading family results on OSWorld-Verified / WebArena-Verified.
• Footprint: ~794GB BF16 weights—steep serving bar.

Caveats

Numbers follow the report's protocols/checkpoints; “Ultrafast” latency claims may not apply to these weights. Isolate the runtime and human-verify consequential actions.

Who it is for

• Labs/platforms benchmarking open computer-use agents at MoE scale.
• Teams with multi-accelerator clusters that can host Qwen3.5-MoE.

Getting started

1. Read the HF model card and arXiv:2611.02102.
2. hf download the weights and verify checksums.
3. Integrate the official Harness; keep the normalized_1000 contract.
4. Evaluate OSWorld-like tasks in a sandboxed desktop/browser before any production use.
