I'm using it fine through both aistudio and vertex ai, direct API calls
It's not at all hard generally, the core of this issue is centered around gemini-cli which is a hot pile of trash. The inability to get keys or account credentials (like why even use an API key, Google is top notch in auto-auth/WIF)
Insanity to me how gemini-cli is so bad at the basics with so many great Google packages in open source that handle all this transparently. All I need to do is have my gcloud authd with the right account/project. I sarcastically assume his is because they vibe coded gemini-cli and it implemented everything from scratch, missing out on reusing those great packages
If you mean Antigravity then.. how? Their docs say you can't do this.
If you mean Gemini then I personally haven't had issues but haven't tried to productionize a Gemini app. The OPs account seems to reflect other comments here.
I suspect Antigravity to be a big flop like gemini-cli. They are so bad in this area they couldn't even write an extension or fork oss-code, instead spending $2B to pork an open source project with someone else's branding
I read someone on here who is using Gemini via OpenRouter because it was the only way they could pay for it.
