I see Command-R+ but not Command-R marked for tool use. The model is geared for it, much easier to fit on commodity hardware like 4090s, and Ollama's own description for it even includes tool use. I think it's just not labeled for some reason. It works really well with the provided ollama-python package and other tools that already brought function calling capabilities via Ollama's API.
