I’ve been using Antigravity 2.0 daily for months and it’s usually blazing fast, but since yesterday the response times have fallen off a cliff. There are no crash warnings, rate limits, or error codes—everything technically works, but the initial TTFT (time-to-first-token) is crawling. Even saying …

3.8 is slow from today evening but 3.7 is working well

I was developing a game engine with Gemini 3.8 Flash-High. It was very fast and stable, and 2 days ago I had that server error notification, and after that day it’s very slow. Even can’t do some simple stuff and have a lot of bugs.

3.8 has been very slow for the past 2 days. Tested now 3.7 and it’s working well

Hey All, Thank you for bringing this to our attention. Our engineering team is aware of the situation and is actively investigating the performance degradation with the Gemini 3.8 Flash model. As a temporary workaround while we work on a fix, many users have found that switching the active model t…

Yeah Gemini 3.8 is super slow, but also Opus 4.6 constantly gets terminated

I tried with new chat right now and It seems fine

@mark14 @RD1 , Yes, this issue has been resolved. Thank you everyone for your patience.

This is awful. Gemini has been super slow since yesterday. It feels like I’m using Codex instead of Antigravity. HEY, GOOGLE DEVELOPERS, FIX THIS PROBLEM. WHY DID WE CHOOSE YOU? FOR YOUR FAST SOLUTIONS!

We need this to happen ! We need a Antigravity status page!

Gemini 3.8 in Antigravity is too slow!

I think it might be fixed to normal speed again?
