Google AI Studio (Gemini API)
A Gemini API free tier for projects, with limits shown in AI Studio.
Free tier
What “free” means here From the provider's documentation
- An active project or free trial qualifies for the free tier.
- Google doesn't publish free-tier numbers on its rate-limit page; your project's limits are shown in AI Studio.
- Moving to paid tiers requires Google Cloud billing.
Checked Sep 29, 2026. Limits and terms change; the provider's page always wins.
Your data on the free option
Google's terms say content sent to unpaid services is used to provide, improve and develop Google products, and human reviewers may read it after it's disconnected from your account. Google says not to send sensitive, confidential or personal information.
Use it with cheapoS
- Create a key on Google AI Studio (Gemini API)'s own site. Never paste it into cheapos.lol, a public chat or a repository.
- Add it to your local gateway. In cheapoS, open Models → Open OmniRoute, add the provider and key, then refresh models. Connection guide ↗
- Start small. Pick a tool-capable model and a task you can check before relying on the quota.
