Bytedance Releases UI-TARS-1.5

"""

ByteDance has released UI-TARS-1.5, an updated version of its multimodal agent framework focused on graphical user interface (GUI) interaction and game environments. Designed as a vision-language model capable of perceiving screen content and performing interactive tasks, UI-TARS-1.5 delivers consistent improvements across a range of GUI automation and game reasoning benchmarks. Notably, it surpasses several leading models—including OpenAI’s Operator and Anthropic’s Claude 3.7—in both accuracy and task completion across multiple environments.

"""

Outperforms Antrhopic Computer Use and OpenAI Operator, and it is Open Source. Uses their own Vision-Language Model, which does what Rabbit's LAM wish it could have done.
