🇺🇸 Google Gemini 免费 LLM API

📌 备注：The Gemini API free tier is available to developers in the EU, UK, and Switzerland; the [available regions](https://ai.google.dev/gemini-api/docs/available-regions) page lists these regions. The [terms](https://ai.google.dev/gemini-api/terms) still require you to use only Paid Services when you make an API Client available to users in the European Economic Area, Switzerland, or the UK. Google no longer publishes per-model free-tier rate limits; check your quotas in [AI Studio](https://aistudio.google.com/). Free-tier prompts may be used by Google to improve products, except for users in the EEA, Switzerland and the UK, where the paid-services data terms also govern the unpaid quota, so those prompts are not used to improve Google products. `gemini-3.1-flash-lite` is on the [deprecation schedule](https://ai.google.dev/gemini-api/docs/deprecations), with a shutdown date of May 7, 2027 and `gemini-3.5-flash-lite` as its replacement; the row stays because the model is live and free today.

额度与限速可能随时调整，请以 Google Gemini 官网 为准。
