Researchers working on phone-operating agents get free Apache 2.0 weights, but there is no hosted service or app.

Kenning's take

What it does

MAI-UI is a family of GUI agent models from Alibaba's Tongyi lab that read a phone screen and carry out multi-step tasks in apps on their own. Alibaba released the 8B and 2B versions as free weights on Hugging Face in December 2025, with a technical report, and reported top scores on mobile benchmarks such as AndroidWorld and ScreenSpot-Pro. In July 2026 the team followed it with Qwen-UI-Agent, which extends the work to computers, browsers and search.

• Model sizes from 2B to 235B, with 8B and 2B weights released
• Pure-vision control of smartphone apps
• 76.7% on AndroidWorld for MAI-UI-235B (team figure)
• Apache 2.0 licence
• Successor Qwen-UI-Agent covers mobile, computer and web
