Frequently asked questions
They have a free tier, not unlimited use: expect rate limits, daily caps or lower priority. Check the provider's terms before you build on one.
The list is ranked by quality. Free tiers usually cover smaller or older versions, so compare the free model with its paid sibling before choosing.
Sign up with a provider that has a free tier, such as Google AI Studio for Gemini, or an aggregator that offers free model variants.
