Google AI Studio provides free browser-based access to Gemini AI models for prompt testing, API key generation, and multimodal application prototyping.
Free tier (verified July 2026): Gemini Pro & Flash free, 15 requests/min
How we checked: read from the vendor's official documentation — source
Checked while auditing the free-API collection. Google publishes a genuine free tier for the Gemini API — a free key, free input and output tokens on certain models — which makes this one of the few listings that could honestly carry a free-API attribute.
| What | What we found | Status |
|---|---|---|
| Free tier | Real. The pricing page lists a Free Tier with "Limited access to certain models", "Free input & output tokens" and Google AI Studio access. | Confirmed |
| API key | Free to obtain. The docs carry a "Get API key" route through aistudio.google.com with no payment step. | Confirmed |
| The trade | Free-tier content is used to improve Google's products. That is stated on the pricing page, and it is the actual cost of the tier.Worth surfacing to a reader deciding whether to send production data through it. | Confirmed |
| Free-tier rate limits | Not on the pricing page. It defers to a separate rate-limits document we did not read on this date. | Not yet checked by us |
| Credit card requirement | Not stated either way on the pricing page.The page shows a "Get started for Free" route with no payment step, but absence of a mention is not a finding. | Not yet checked by us |
Checked by the TheToolsVerse Verification Desk — by reading the vendor's own published pages, not by testing the product in an account. Google AI Studio can change prices at any time without notice. The date above is the last time we looked; if it looks old, treat every figure here as unconfirmed and check Google AI Studio directly before paying.
