Google AI Studio

Set up Coreply with Google AI Studio to use Gemini models via the free Gemini API.

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.

Setup

1. Get your API key

   Go to aistudio.google.com/apikey and create a new API key.

2. Enter your credentials in Coreply

   Open Coreply’s settings and fill in the following values:

   Field	Value
   API URL	https://generativelanguage.googleapis.com/v1beta/openai/
   API Key	Your key from AI Studio
   Model Name	See recommended models below

3. Choose a model

   The following models are recommended for use with Coreply on AI Studio:

   gemini-2.0-flash
   gemini-2.0-flash-lite
   gemini-2.5-flash-lite
   

Caveats

gemini-2.5-flash reasons by default in AI Studio. This adds latency before each suggestion and is not recommended for real-time use.

The gemma-3 family in AI Studio does not support system instructions, which Coreply requires. These models are not compatible.
