The chat templates of all Gemma 4 models have been updated 7 days ago, to fix some bugs related to invoking tools.

So any tests done with models that have not been updated during the last days are no longer relevant and they must be repeated after updating the models and regenerating any other file formats, like GGUF files.

I read somewhere you need to drop temp to 0.1 on gemma for tools.

Not sure why (too amateur sorry).

Though I think qwen was natively trained on toolcalling.
