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.
