We have been using gemini-2.5-pro for months and it’s been working very well. But suddenly we got the following response today:
[{
“error”: {
"code": 503,
"message": "The model is overloaded. Please try again later.",
"status": "UNAVAILABLE"
}
}
]
I also attach a screenshot of the rate limit (we have far to reach the limit). The API error/day chart shows a spike today (close to 0 in other days). This only affected gemini-2.5-pro only. Our Quota tier is 3
What are the reasons and how we can fix? This has affected many of our users.
