It observes the browser through screenshots and acts on the user's behalf by emitting structured tool calls — click, type, scroll, visit URL, web search, and so on — to complete tasks end-to-end. The model is vision-only at perception time: it sees the browser through screenshots, not the DOM or accessibility tree. Internal reasoning and trajectory history are tracked as text. Given the latest screenshot and prior actions, it predicts the next action with grounded arguments (e.g., pixel coordinates for a click). Fara1.5-27B is supervised fine-tuned from Qwen3.5-27B on data generated by **FaraGen1.5**, our multi-agent pipeline that synthesizes web tasks, executes trajectories to solve them, and verifies the results before training. It's co-designed with **MagenticLite**, and that's the recommended deployment for both research and production. Highlights - **End-to-end web task completion.** Fills forms, books reservations, applies for jobs, plans trips, runs shopping carts.
