OpenVisTool Model
This checkpoint is part of the model family released with OpenVisTool, an open recipe for synthesizing instructive visual tool-use trajectories. These models can interleave reasoning, visual tool calls, tool observations, and final answers to solve visually complex tasks.
The checkpoint is supervised fine-tuned on OpenVisTool-42K, which contains 42,048 tool-use trajectories. The release includes four checkpoints:
| Checkpoint | Base model |
|---|---|
| qwen3vl_8b_openvistool_42k | Qwen3-VL-8B-Instruct |
| qwen35_4b_openvistool_42k | Qwen3.5-4B |
| qwen35_9b_openvistool_42k | Qwen3.5-9B |
| qwen35_27b_openvistool_42k | Qwen3.5-27B |
