Xenon said on Thursday it has released as open source Hunmin VLM 397B, an AI model that recognises computer screens and directly operates them to carry out tasks. Built on Qwen3.5-397B, the model scored 75.6 on ScreenSpot-Pro to rank second on Hugging Face's official leaderboard, and 70.5 on OSWorld in a Linux environment, 22.3 points above the base model. The company trained it using eight Nvidia B200 GPUs.
