# 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.

<Note>
  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.
</Note>

## Setup

<Steps>
  <Step title="Get your API key">
    Go to [aistudio.google.com/apikey](https://aistudio.google.com/apikey) and create a new API key.
  </Step>

  <Step title="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                               |
  </Step>

  <Step title="Choose a model">
    The following models are recommended for use with Coreply on AI Studio:

    ```text theme={null}
    gemini-2.0-flash
    gemini-2.0-flash-lite
    gemini-2.5-flash-lite
    ```
  </Step>
</Steps>

## Caveats

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

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