Update:
I left Antigravity unused for 24 hours. Then I used Gemini 3 Low with 3 prompts and it dropped me to 60%.
I still believe the following:
Given the performance of Opus 4.5, Google took advantage by offering the model with a generous quota for users with a free one‑month trial (which is my case), along with Gemini 3 Pro. Now the quota is pathetic.
MY RECOMMENDATION:
Windsurf offers SWE 1.5 for free, and it’s far better than Gemini 3 Flash. I strongly recommend switching to Windsurf or Cursor and stop dealing with this IDE and its misleading quotas.
