Am I missing something or are the Ollama versions of this (https://ollama.com/library/gemma4/tags) text-only for now?

Since ollama has diverged from llama.cpp, it will take a bit of time for ollama to support multi-modality. If you're using plain llama.cpp it looks like a PR has already merged for this model with vision and audio support:

https://github.com/ggml-org/llama.cpp/pull/24077

Just use llama.cpp or Unsloth Studio which wraps it, I don't know why anyone use Ollama anymore.

Highly recommend just dropping Ollama. You can download binary releases of llama.cpp for every platform and run them trivially in 5 seconds. Ollama serves no purpose other than to take open source work and rebadge as its own, while providing inferior functionality

To anybody else wondering: Seems like the models supporting image input are just starting to show up. https://ollama.com/library/gemma4:12b-mlx now shows as supporting it, but curiously the overview on https://ollama.com/library/gemma4/tags still lists it as text only. Cache invalidation remains difficult :)

Stop using ollama

Ollama is a shitty project that steals from the open source community, don't use it, use llama.cpp instead.
