Hey there - I've reviewed your changes - here's some feedback:

Consider abstracting the repeated Imagen 4 model blocks into a factory or shared base config to reduce boilerplate and the chance of inconsistencies.
Verify the displayName formatting across GA and preview variants (e.g. "Imagen 4 Ultra" vs "Imagen4 Ultra") to ensure naming consistency.
You may want to reorder the array so enabled GA models are grouped before the disabled preview entries for improved readability.
