Gemini 2.5 Pro not working anymore from API (free tier)

I've been working at an application based on Gemini 2.5 Pro API – free tier. It had always worked without any issues, I only made a handful of requests each day, nothing heavy. I hadn’t touched the project for about a week, and when I picked it up again yesterday, I immediately got a quota-exceeded error at the first API call:

Error during answer generation: Error: [GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-pro:generateContent: [429 Too Many Requests] You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: https://ai.google.dev/gemini-api/docs/rate-limits. To monitor your current usage, head to: https://ai.dev/usage?tab=rate-limit.

I switched to an API key from another G account – same error.

I didn't used at all none of these accounts since last week, so no usage at all recently.

When I checked the documentation at https://ai.dev/usage?tab=rate-limit, I noticed something odd: Gemini 2.5 Pro isn’t listed anymore. Only Flash and Flash Lite show up. On https://ai.google.dev/gemini-api/docs/rate-limits they also removed the explicit rate/quota limits for free tier.

WTF Google… did you silently pull Gemini 2.5 Pro from free API usage? 😠
