I’m on the Google AI Ultra for Business plan, and I’ve been getting this error about 90% of the time for the past three days. I’ve tried all models, and the issue behaves the same across both Gemini and Claude models.
Any idea what this might be and how to fix it? In the output (doesn’t make any sense to get hit by 429 - too many requests)
tried with another account (PRO) there it works perfectly, but not in ultra/business
Additional info here, Only gemini flash model is working on ultra plan, others terminating, I found that other people also facing same issue on REDDIT and X(twitter), so it’s likely server issue, please resolve it ASAP
Hi @Mark5_Parker
Welcome to the Google AI Forum!!!
Thank you for reaching out! This channel is dedicated to supporting users of the Gemini API and Google AI Studio. For questions about other Google products, the best place to find help is their dedicated support pages or community forums.
Thanks!
thanks for reply, Did’t found such pages earlier, could you link them? antigravity does’t have support page
Hi @Mark5_Parker, there is no support page for Antigravity yet on the AI Forum.
The error message “Model capacity exhausted” distinguishes this from a standard user quota limit. This indicates a server-side availability issue rather than a restriction on your account’s billing or usage limits.
We apologize for the interruption to your workflow. If you are still seeing the error, please let us know.
We also highly recommend filing a bug report directly through the Antigravity in-app feedback tool. You can access this by clicking the Feedback icon in the top-right corner of the interface and selecting Report Issue.

its very strange, i was cranking all day and then it just stopped.
same problem here with ultra plan. cant do any work since 24h. crazy that i think the devs not even have a clue about it. nowhere is an answer… back to claude code…
