Gemini 3 is no longer available in v0
We release these models as previews temporarily to get lots of data on how well they work for various v0 use cases. If they’re great everything we’ll keep them around, if it’s good at some things we’ll work it into the v0 agent so it calls it under the hood.
In this case Gemini 3 Pro was really prone to infinite loops at the model level (this doesn’t only affect v0) that were unsolvable so we replaced it with Opus
