I am currently trying to increase the GPU quota for Google Cloud Platform. However, I am unable to search Google Compute Engine API for increasing the GPU quota.
No option comes up when I search for "Compute Engine API" or "GPU All Regions"
Has the format of the search criteria been changed? Previous tutorials are deprecated.

Sorry for the late answer! The UX is a little confusing but the filter works fine.
One way of finding the GPUs: you can directly click on the filter then select "name" and start typing "GPU" then some suggestions will popup..
hope this helps
