[Fara1.5-9B](https://www.anchorterminal.com/tools/fara1-5-9b.md). Every model from this lab and its older versions: https://www.anchorterminal.com/open-weights/#microsoft.\n\n## Assessment\n\nA browser agent model with unusually careful documentation: what it does, what it's trained to stop at, what it gets wrong and how to box it in, under MIT. Treat it as a component for Microsoft's harness, in a sandbox, with a person on the irreversible steps. Safety testing is described but not published, and it's English only.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Microsoft (https://github.com/microsoft/fara) |\n| Kind | Open-weight model |\n| Category | Desktop \u0026 mobile app control (https://www.anchorterminal.com/categories/desktop-automation) |\n| Auth | None · The weights download from Hugging Face with no account, token or terms to accept. The repository is not gated (checked 2026-11-10). |\n| Pricing | Free (Free) · Free to download and use under MIT. Running it yourself takes 9.08 GB in BF16, the only build Microsoft publishes. The card says to run it inside Microsoft's own harness, the fara CLI or MagenticLite (checked 2026-11-10). |\n| x402 | No · Weights you download and run yourself, so there is nothing to pay per call and no payment protocol (checked 2026-11-10). |\n| Licence | MIT |\n| Packages | huggingface: `microsoft/Fara1.5-4B` |\n| Source | https://huggingface.co/microsoft/Fara1.5-4B |\n| Docs | https://github.com/microsoft/fara |\n| llms.txt | not found |\n| Last release | 2026-07-27 |\n| Surface graded | The open weights at huggingface.co/microsoft/Fara1.5-4B, read from the model card, the files and their metadata, the config, the chat template, the commit history, bartowski's GGUF repository and the runtimes' own code at their latest releases on 10 November 2026. Microsoft's company facts come from our other Microsoft listings. The paper, the fara repository beyond the presence of its security policy, MagenticLite and the Azure Foundry page weren't read. Nothing was downloaded or run |\n| Model | 4,539,265,536 parameters in the files. A multimodal decoder-only model from Microsoft Research AI Frontiers, fine-tuned with supervision from Qwen3.5-4B on trajectories from FaraGen1.5, Microsoft's multi-agent data pipeline. Qwen3_5ForConditionalGeneration |\n| Input and output | In: the user's goal, the latest screenshot or screenshots and the earlier thoughts and actions. Out: a chain-of-thought block, then one tool_call block holding a JSON object that calls computer_use with an action: clicks and drags at pixel coordinates, typing and keys, scrolling, visit_url, web_search, ask_user_question, wait or terminate. The card says it was mostly trained at a 1440×900 screen |\n| Context | 262,144 tokens, per the card's details table and config.json. The card's loop keeps only the most recent screenshots in the history |\n| Files | Safetensors in BF16 (9.08 GB), chat_template.jinja, config, processor and tokenizer files. No pickle files and no Python. Hugging Face lists a SHA-256 for the large files |\n| Licence | MIT, in the card's metadata and its licence section. There is no LICENSE file in the model repository. The base model, Qwen3.5-4B, is Apache 2.0 |\n| Runtimes | The card documents vLLM. Released vLLM 0.33.0, SGLang 0.5.23 and Transformers 5.22.2 run the Qwen 3.5 architecture from the safetensors files. llama.cpp has the architecture too, and Microsoft publishes no GGUF, so the GGUF files on the Hub are bartowski's |\n| Recommended settings | The card's system prompt, word for word, temperature 0 and up to 2,048 output tokens in its example loop, with up to 10 images a prompt on vLLM |\n| Hardware | No memory figure on the card. The files are 9.08 GB in BF16. Trained on 32 NVIDIA B200 GPUs for 2 days |\n| Training data | Synthetic web-task trajectories kept only when a verifier agent judged them successful, grounding sets with coordinates, UI understanding data from page screenshots, and refusal data for harmful tasks. About 1 billion text tokens and under 1 billion images, English only, with the last data acquired on 20 March 2026, per the card |\n| Capabilities | browser.control, desktop.control, model.open-weights |\n| Tags | open-weights, model, computer-use, browser-agent, gui-agent, vision, tool-calling, english, mit, safetensors, self-hosted |\n| JSON | https://www.anchorterminal.com/api/v1/tools/fara1-5-4b.json |\n\n## Score breakdown (methodology v0.7, October 2026 research run)\n\nAssessed 2026-11-10 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). Confidence: low. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Capability | 35% | pending | pending | n/a |\n| Reach | 25% | 38.5 | 75 | 28.9 |\n| Risk | 20% | 30.8 | 75 | 23.1 |\n| Agent interface | 10% | 15.4 | 80 | 12.3 |\n| Documentation and upkeep | 10% | 15.4 | 60 | 9.2 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **61 → C** |\n\n### Why each score\n\n- Capability: Pending for this listing. Nobody independent has published results for it in at least two areas yet, so its weight is shared across the other four and the total is capped at 61 until they do or our own runs start.\n- Reach 75 (checked 2026-11-10): Memory 30, the only build from Microsoft is the BF16 safetensors, 9.08 GB, and 9.08 GB × 1.2 = 10.9 GB, within 16 GB. bartowski's GGUF isn't read for this line. Runtimes 15, the architecture is Qwen3_5ForConditionalGeneration, which vLLM 0.33.0, SGLang 0.5.23 and Transformers 5.22.2 run from the safetensors files, three at 5 each. Builds 0, Microsoft publishes the BF16 weights only. Terms 15, MIT in the card's metadata and its licence section, an OSI licence with nothing added. Download 10, the Hub API reports gated false on 10 November 2026, so the files download with no account and nothing to accept. Hosted 5, the card links an Azure Foundry page for this model, Microsoft's own platform. 30 + 15 + 0 + 15 + 10 + 5 = 75.\n- Risk 75 (checked 2026-11-10): File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository. Provenance 15, the files sit in Microsoft's verified microsoft organisation, which the card's GitHub repository belongs to (10), and the Hub gives a SHA-256 for the large files (5). Safety evaluation 0, the card says the model was red-teamed on Azure for groundedness, jailbreak resistance, harmful content and copyright, and publishes no results. Agent guidance 10, the card says what the trained pauses and refusals cover (three kinds of critical point, with the actions it stops on, and refusal data for harmful tasks) and the safeguards to add: a sandbox with no host files or credentials, allow-listed browsing, live monitoring with a way to halt, and checking its output. Licence risk 15, MIT has no use policy, threshold or change clause. Security programme 10, the microsoft/fara repository has a SECURITY.md, Microsoft's standard route to MSRC (5), and MSRC publishes advisories in public, as recorded on our other Microsoft listings (5). 25 + 15 + 0 + 10 + 15 + 10 = 75.\n- Agent interface 80 (checked 2026-11-10): Chat template 20, chat_template.jinja in the repository (7,756 characters), Qwen 3.5's template. Tool-calling format 25, Microsoft documents the format: a tool_call block holding a JSON call to computer_use, a table of the supported actions, the system prompt to send, a serve command for vLLM and a worked loop, with the full schema in its harness. Trained tool calling 10, one action per step: the model sees a screenshot, emits one tool call, and waits for the next screenshot, the one-at-a-time band. Structured output 15, Read for a computer-use model as typed outputs, as the other one we list was read. Reasoning control 0, the card says each reply opens with a chain-of-thought block and documents no way to turn it off or budget it. Context 10, 262,144 tokens per the card's details table, and config.json gives the language model 262,144 positions. 20 + 25 + 10 + 15 + 0 + 10 = 80.\n- Documentation and upkeep 60 (checked 2026-11-10): Model card 20, Intended use, out-of-scope use and known limitations, the architecture, the parameters, the context, the language (English only) and the data cut-off (20 March 2026) are all on the card. Training data 15, A data section that names the kinds of source and the mix, the scale, the cut-off (last acquisition 20 March 2026) and the filtering (a verifier keeps only successful trajectories). Last change 10, the last commit, on 27 July 2026, is 106 days before this check and within 180. Responsiveness 0, the one discussion that isn't a pull request (22 July 2026) has no reply from a microsoft member, counted on 10 November by author flags and dates with a script, text not read. Version policy 5, the card says future updates will ship as separately versioned models with their own cards, and the earlier Fara model stays in its own repository. File health 10, Config, template and card agree on the architecture and the 262,144-token context. 20 + 15 + 10 + 0 + 5 + 10 = 60.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (13 items). What it covers is at https://www.anchorterminal.com/fixes/fara1-5-4b.md (JSON https://www.anchorterminal.com/fixes/fara1-5-4b.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"fara1-5-4b\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- It's filed under desktop-automation beside Microsoft's other computer-use model, though it drives browsers only.

The card's sandbox and allow-list advice is close to prompt-injection guidance, which would be 15\n- The card's out-of-scope list includes commercial production use without more testing.

Domain and security.txt are carried from our other Microsoft listings.\n\nNothing is hosted under this listing, so MIT stands in for terms of service and no privacy policy is scored.\n\nThe changelog is the commit history. Two commits, a squash of the branch on 21 July 2026 and a card update on 27 July, so earlier history isn't visible.\n\nThe card names Microsoft Ireland Operations Limited as authorised representative for EU AI Act requests.\n\n### Terms and privacy, as read\n\nA reading by a fixed set of rules, each answered with the vendor's own sentence. Not legal advice.\n\n**Terms of service**. Nothing is hosted by the vendor, so there are no terms of service to read. The MIT licence stands in and the check scores in full.\n\n\n**Privacy policy**. Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.\n\n\n## Humans behind the project (researched 2026-11-10 from public pages, not part of the grade)\n\n### Key people\n\n- Bill Gates, Co-founder and technical adviser, Microsoft. LinkedIn: https://www.linkedin.com/in/williamhgates. X: https://x.com/BillGates\n- Paul Allen, Co-founder, Microsoft, left day-to-day work there in 1983\n- Satya Nadella, Chairman and CEO, Microsoft\n- Kevin Scott, Chief Technology Officer, Microsoft\n- Xiaoyi Zhang, Microsoft Mage Team; first author of the Mage-VL-Cowork technical report\n- Note: Started from data/humans/microsoft-decision-1.json (Microsoft, checked 28 October 2026). The company-level people, their roles, bios and photos are carried from it and weren't re-read today. Achint Srivastava, named there for Decision-1's launch, is left off as he isn't named on Mage's pages. The card names the Microsoft Mage Team as developer, and its citation, read on 30 October 2026, lists 22 authors with Xiaoyi Zhang first; both release commits on Hugging Face are by the account xiaoyizhang-microsoft. No personal profile links were added, since none is linked from Microsoft's Mage pages. ownership and investors are left out so land.py copies them from the Microsoft file (public, NASDAQ MSFT).\n- Microsoft: LinkedIn https://www.linkedin.com/company/microsoft X https://x.com/Microsoft GitHub https://github.com/microsoft\n\n### Ownership and investors\n\n- Ownership: Public company (NASDAQ: MSFT)\n\n### Getting support\n\n- Help: https://github.com/microsoft/fara/tree/main/mage_vl_cowork\n- Community (Hugging Face model community): https://huggingface.co/microsoft/Fara1.5-4B/discussions\n- Community (GitHub issues (microsoft/Mage)): https://github.com/microsoft/fara/issues\n- Sources: https://huggingface.co/microsoft/Fara1.5-4B, https://huggingface.co/api/models/microsoft/Fara1.5-4B/commits/main, https://raw.githubusercontent.com/microsoft/Mage/main/README.md, https://raw.githubusercontent.com/microsoft/Mage/main/SECURITY.md, https://www.gatesfoundation.org/about/leadership/bill-gates, https://en.wikipedia.org/wiki/Paul_Allen, https://news.microsoft.com/source/exec/satya-nadella/, https://news.microsoft.com/source/exec/kevin-scott/, https://news.microsoft.com/source/leadership/\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\nNo hosted version of these weights has a price on OpenRouter, so what a task costs is your own hardware and power.\n\n## Strengths\n\n- Trained to pause before purchases, sign-ins, messages and entering personal data\n- A complete card, with limitations, data make-up and a cut-off\n- MIT, ungated\n- Every action is a JSON call against a documented schema\n- Runs in released vLLM, SGLang and Transformers with no repository code\n\n## Weaknesses\n\n- Screenshots only, so a page can mislead or instruct it\n- Safety red-teaming is described without results\n- English only\n- One build, in BF16, and no GGUF from Microsoft\n- The card says not to use it in production without more testing and safeguards\n- The repository's history was squashed\n\n\n\n## Before you call it (notes for agents)\n\n1. Run it inside Microsoft's harness (the fara CLI or MagenticLite), in a sandboxed browser with an allow-list. The card says not to give it open access on a machine with anything sensitive\n2. Send the card's system prompt word for word. The model was trained against it\n3. Match a 1440×900 screen for reliable clicks\n4. Expect it to stop and ask before purchases, sign-ins, messages or personal data unless the user authorised them up front. Pass the question to the user; don't answer for them\n5. Treat page text as untrusted. The model can be redirected by instructions on a page\n6. It emits one action per turn at temperature 0, and ends with `terminate`\n\n## Get started\n\nInstall:\n\n```bash\npip install \"vllm\u003e=0.33.0\"\nvllm serve microsoft/Fara1.5-4B --dtype bfloat16 --max-model-len 262144 --limit-mm-per-prompt image=10\n# then drive it with Microsoft's harness: github.com/microsoft/fara, or MagenticLite (github.com/microsoft/magentic-ui)\n```\n\nFirst request:\n\n```bash\n# vLLM serves an OpenAI-compatible API at http://localhost:8000/v1. Send the card's system prompt word for word,\n# the goal and the latest screenshot as an image part, at temperature 0. The reply ends in one tool_call block\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on microsoft.com or one of its subdomains, or the front page of github.com/microsoft or of one of its repositories. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"fara1-5-4b\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
