I built some BigQuery workflows on 2.0 and 2.5 flash lite that are something like 6x more expensive with 3.1 flash lite.

I tried 3 flash for months and it didn’t work using Googles own vertexai integration because it’s been in preview mode for months.

Not wanting to pay significantly more and do a bunch of rework isn’t a smell.

They left a large gap in their new pricing vs the prior generation, and if you had a working use case that sucks. The model is >99% reliable for my use case so there’s nothing to gain from a smarter model.
