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
