For most parts, gemini 2.5 flash 04-17 and 05-20 works great.
However, I noticed that it keeps tripping on certain requests (500 error). I have a retry mechanism that retries for 20 times with up to 10 mins backoff in between, but the request still returns a 500 error..
When I try this request hours later, it works. Maybe the error is being cached?
