Getting rate limits increased (tier upgrades)

I’m trying to use the flash-2.5-tts model to create many short audio clips, however I am currently in tier 1 so my rate limit is 10 RPM. To get to Tier 3(which I would like), I need to spend $1k, however I can’t do this with such a low rate limit. With OpenAI I can simply add money to my account to raise the limits. Does google raise limits? I made a request to the gemini team, but its been 2 weeks and I haven’t heard anything back. Just wondering if anyone has been successful in upgrading their tier.

Hi @MasihS,

Thanks for reaching out. Yes, our team does review and approve requests for rate limit increases. Processing time can vary depending on the current request volume and a few other factors.

Hi its been nearly a month now, is there any way I can escalate this?
