Holo4-35B-A3B
[!IMPORTANT] Holo4 family:
Model summary
Holo4-35B-A3B is a vision-language model (VLM) for Computer Use, built on Qwen3.6-35B-A3B and developed by H Company. Used with the hai-agents harness, it can send screenshots and tool results to the model, then execute its requested clicks, typing, code, and tool calls.
This demo shows Holo4-27B using FreeCAD to build a replica of the Eiffel Tower. More examples in the blog post.
Usage
The harness sends screenshots and tool results to Holo4, executes the model's requested actions, and sends the results back. It can give the model access to application tools and code execution.
