Our company is going through the exact same issue. We used to use Antigravity 2.0 with Gemini Pro 3.1 High. This week, we had to migrate to Google’s enterprise plan, which forced us to authenticate using a Google Cloud project.
Later, while testing, we noticed that the Gemini Pro 3.1 High model took up to 3 minutes to run a commit skill—where the job is just to process a git diff and write a conventional commit in English. This used to be super fast, but I don’t know what they’ve done because now it’s incredibly slow, and we no longer see it as a viable tool for our day-to-day work in the office.
