Google's Gemini API provides a free tier for developers and small projects. Free-eligible models are the Flash and Flash-Lite families (e.g. Gemini 2.5 Flash, Gemini 2.5 Flash-Lite, newer 3.x Flash Lite variants) with free input/output tokens and relatively generous RPM/RPD quotas, which Google no longer fully publishes per model — check your effective limits in Google AI Studio, as they change over time (free-tier cuts happened historically). The free tier needs a Google account but no billing/credit card; rate limits apply per project. The API supports both the native protocol and an OpenAI-compatible endpoint.
