I can not go on working with the app

Hey! The most common reason you would get this as a new user is you are trying to access a model which can only be accessed via a paid account (example: Gemini 3 Pro). We are working to make the error message more clear, but in the meantime, you can upgrade to a paid account through AI Studio: https://aistudio.google.com/api-keys

Currently I can see tier1 quota linked with my project, but still report the same error.

Also, before I was using free tier, if I exceeded the quota, will it replenish the next day? or monthly?

Thank you.

It feels like I’ve tried everything, yet I still keep getting the error: “Failed to call the Gemini API: user has exceeded quota. Please try again later.” I’ve upgraded to Tier 1, generated a new API key, linked the project to that key, created a .env file in the project root, and even hardcoded the key directly into geminiService.ts. None of these attempts have resolved the issue.

Edit: I also switched from gemini-3-flash-preview to gemini-2.5-flash after reading that the preview model has stricter usage limits.

Edit2: The .env file I created for the api-key was automatically removed after some time. I also made a copy of another file as a backup of the original, and that file was removed as well. It seems that manually created files cannot be retained.
