I just updated Antigravity IDE to 2.1.4 using “Restart To Update” button. There is a new quota UI which displays that I have used 13% of my weekly quota and that I have 100% of my 5 hour quota left for Gemini models, but in the chat interface where I have Gemini 3.5 Flash (Low) selected, it has a warning saying: “Your quota for this model is running low”.
You have actually used 87% of your weekly limit (13% left). That’s why you see the quota message.
