Free AI API tiers

Free tiers are the best deal in AI: ongoing allowances you can use indefinitely within rate limits, usually with no credit card. Here are the verified provider free tiers.

The short answer

Start with the Google AI Studio (Gemini) free tier — no card, available in every supported region — and Cohere’s free trial keys for text generation, embeddings and reranking. Both are ongoing, so you can build without a clock ticking.

Frequently asked questions

What is a provider free tier?
A free tier is an ongoing, no-cost allowance to use a provider’s API within set rate limits — it does not expire like a trial credit. Examples include the Google AI Studio (Gemini) free tier and Cohere’s free trial keys.
Which AI API free tiers need no credit card?
The Google AI Studio Gemini free tier and Cohere trial API keys both require no credit card to start, and stay free within their rate limits.
Do free tiers ever change?
Yes — limits and model availability change over time. That is why we show a last-verified date on every offer and re-check provider free tiers on a regular cadence.
