About

What Fara1.5 is

Fara1.5-9B [](https://aka.ms/fara1.5) [](https://github.com/microsoft/fara) [](https://huggingface.co/papers/2606.20785) [](https://aka.ms/fara1.5-9B-foundry) Fara1.5-9B is a multimodal computer use agent (CUA) for web browsers, from Microsoft Research AI Frontiers. 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). Fara1.5-9B is supervised fine-tuned from Qwen3.5-9B 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. Please use only with the harness developped in Github/fara CLI or Magentic-Lite. 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. Not just clicking around — sequencing actions toward a goal. - Vision-only perception. Operates on screenshots alone, no DOM access required. Matches the input modality available to a human user. - Coordinate-grounded actions. Predicts pixel-level click and drag targets directly. No separate grounding model needed. - Critical-points safety design. Trained to stop and ask before personal info entry, payments, submissions, sign-ins, sending messages, or other irreversible actions — even if it could technically continue. - 262K context. Long enough for multi-screenshot trajectories with full action history. - On-device viable. 9B parameters means it runs on a single A100/H100/B200 with room for the screenshot history. Model Details Recommended Deployment: MagenticLite The safest way to run Fara1.5-9B is inside MagenticLite, which provides: - Sandboxing — the browser run

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys fara1-5 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (fara1-5 below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"fara1-5","messages":[{"role":"user","content":"Hello"}]}'
