I am trying to use it to perform some processing of data, but it is highly unstable, i have retries and even with 3 retries it keeps failing, is there any instability? Also why are you guys deprecating it, if the costs of the next flash lite model are significantly higher than 2.5. Very disappointed…

Recommendation for everyone, if you really really need to make it work, i recommend just using Gemini 2.5 Flash, unfortunately it is the only other sorta of stable model with comparable pricing, but from now on we will stop using gemini models for new features, as they obviously are too unstable to …
