Microsoft Releases Fara1.5: A Family of Browser Computer-Use Agents (4B/9B/27B) That Outperform OpenAI Operator and Gemini 2.5 Computer Use on Online-Mind2Web
Microsoft Research has introduced Fara1.5, a series of three browser computer-use agent models (4B, 9B, and 27B parameters) built upon Qwen3.5. These agents are designed to interact with real browsers by interpreting screenshots and executing mouse and keyboard actions to complete tasks. In evaluations on the Online-Mind2Web benchmark, the largest Fara1.5 model achieved a 72% task success rate, surpassing competitors like OpenAI's Operator and Google's Gemini 2.5 Computer Use. AI
