Clients
"Supported" is often overloaded in local AI.
For Gemma 4, there are at least three separate support layers:
- Model format support
- Runtime feature support
- Client UX/rendering support
A failure in any one layer can make users think the model is broken.
Common Example
- runtime can load model
- client cannot correctly expose a modality or reasoning tag
- result looks like partial functionality
This is not unusual in fast-moving model ecosystems.
How to Evaluate Support Correctly
Before relying on a client claim, test:
- load success
- tool-calling behavior
- long-context stability
- modality features (if needed)
Use your own acceptance checklist, not marketing labels.
Final Takeaway
For Gemma 4, capability claims are necessary but not sufficient.
Operational support must be validated end to end.
