Fara1.5-9B GGUF

GGUF conversions of microsoft/Fara1.5-9B, Microsoft's 9B multimodal computer-use agent for screenshot-driven browser automation.

The files were converted from source revision 8238b75529e98434621204024b149860b8071d33 and validated with llama.cpp build b10066 (86a9c79f8).

The projector is shared by both text-model quantizations. Download it alongside the selected model file for multimodal use.

llama.cpp usage

Fara is a screenshot-driven computer-use model. For image grounding, use at least 1,024 image tokens:

llama-mtmd-cli \
  -m Fara1.5-9B-Q4_K_M.gguf \
  --mmproj Fara1.5-9B-mmproj-F16.gguf \
  --image screenshot.png \
  --image-min-tokens 1024 \
  -ngl 99 \
  -p "Describe the next browser action."

Server example:

llama-server \
  -m Fara1.5-9B-Q4_K_M.gguf \
  --mmproj Fara1.5-9B-mmproj-F16.gguf \
  --image-min-tokens 1024 \
  -ngl 99 \
  --ctx-size 8192

For full computer-use behavior, follow the original model card's system prompt, tool schema, screenshot-history format, and critical-point safety requirements. Microsoft recommends running the browser in a sandbox with domain allow-lists, monitoring, and an immediate pause control. The model was most commonly trained with 1440 x 900 screenshots.

Conversion and validation

• Source: four BF16 safetensor shards, 760 indexed tensors, with no missing, extra, or misassigned tensors.
• Text GGUF architecture: qwen35, 427 tensors.
• Vision projector architecture: clip, 334 tensors.
• Quantization: standard llama-quantize Q8_0 and Q4_K_M without an importance matrix.
• Runtime: both quantizations loaded and generated successfully on an RTX 4090.
• Multimodal: Q4_K_M plus the F16 projector successfully encoded and interpreted a repository screenshot.
