Google AI Studio provides access to Google’s Gemini models through an OpenAI-compatible API. It offers a free tier that works well with Coreply for everyday use.
AI Studio’s free tier has rate limits. If you see the error Unexpected JSON token at offset 0: Expected start of the object '{', but had '[' instead — this is a rate limit response from Google, not a bug in Coreply. Wait a moment and try again, or switch to a paid tier.
