Chromium v120 and up is meant to have shader-f16 by default, but it won't be listed in features here:
https://webgpureport.org/
See:
https://github.com/mlc-ai/web-llm/issue ... 1877115608
I need this feature for use with
@mlc-ai/web-llm, please include it in an update. Thank you.

Same kernel m129 in Chrome and CatsXP
The test results are consistent

When you go to
this site, does it show shader-f16 in the "features" section? (Bottom of the middle column.)

// List of WebGPU feature names, delimited by ,
// The FeatureParam may be overridden via Finch config, or via the command line
// For example:
// --enable-field-trial-config \

This is the only relevant comment that can be found in the source code
Attempt to add startup parameters：
--enable-field-trial-config \
--force-fieldtrial-params=WebGPU.Enabled:UnsafeFeatures/timestamp-query%2Cshader-f16
The test results show that it is not yet open
Are you sure the test results of this page are valid under win? (Mac testing?)

My apologies, it turned out to be a hardware issue, apparently my card doesn't support shader-f16. Very sorry.
