      "Weights uploaded on 26 October 2026. The repository was created at 05:36 UTC and the files went in at 11:15 UTC under one commit by an inclusionAI member, and the UI-Venus collection was updated at 11:19 UTC. On 27 October the Hub counted 10 likes and no downloads yet (https://huggingface.co/api/models/inclusionAI/LBS-27B/commits/main)",
      "Who made it. The GitHub README names seven authors from Wuhan University of Technology, the Institute of Automation of the Chinese Academy of Sciences, Zhejiang University and Ant Group, and the files sit in inclusionAI, Ant Group's Hugging Face organisation, in the UI-Venus collection beside UI-Venus-2, UI-Venus-1.5, GUI-G2 and VISTA. No paper is out yet; the README says citation details will follow an arXiv release (https://github.com/inclusionAI/UI-Venus/tree/LBS)",
      "How it works. The model reads a screenshot, writes its reasoning in think tags, and can ask for up to two crops per turn and three per episode as plain-text \u003caction\u003ecrop_image(...)\u003c/action\u003e lines. The client cuts and returns the crops, and the final answer is a point [x.xx,y.yy] scaled to 0 to 1000 on the original image. It doesn't use the chat template's tool-calling format, and a separate executor is needed to act on a live application",
      "Training, as the card describes it. About 10,000 synthetic GUI grounding examples for a cold-start fine-tune, then 80 GRPO steps at batch size 64 with eight rollouts per prompt, and no general-domain or visual-question data. The GitHub training README says the recorded run used Ascend NPUs. The full training data isn't published; eight prompt rows and 32 recorded rollouts are",
      "inclusionAI's claims, from its own runs with agentic zoom-in, are ScreenSpot-Pro 81.15, OS-World-G (Refine) 84.57, PerceptionBench 59.67 with a self-hosted DeepSeek V4 Flash judge, HR-Bench 4K 89.13 and HR-Bench 8K 87.75. The publisher says its comparison chart mixes setups and judges and isn't controlled. No independent result was found on 27 October 2026, and the ScreenSpot-Pro and PerceptionBench leaderboards have no LBS row (https://github.com/inclusionAI/UI-Venus/blob/LBS/docs/BENCHMARK_OVERVIEW.md)",
