GLADOS-1 — UI-TARS-7B-SFT

Model Description
GLADOS-1 is the first computer-use (CUA) model post-trained using collective, crowd-sourced trajectories.
Leveraging the enourmous PANGO dataset (with primarily Chrome based interactions), it's purpose is to provide a lense as to what's possible with enormous trajectory sizes in computer use.
It also represents the first open-sourced post-training pipeline for UI-TARS, inspired by the existing Qwen2VL finetuning series.
This model is designed to:
- Be compliant. It has been taught to rigorouly follow directions and output action formats compatible with downstream parsers like PyAutoGUI.
- Understand web productivity applications. The Pango dataset primarily contains productivity application usage in browser. Consequently in OSWorld results, we observe significantly improved performance on the Chrome task bench.
- Have strong intuition on visual grounding. Our experiments are detailed more closely here in our research blog.
