Get your Gemini API key

Visit Google AI Studio to create or copy your API key.
Your API key gives you access to Gemini, Google’s multimodal AI model. Keep it private and rotate it if you believe it has been exposed.
Never paste your API key directly into Rocket chat. Always use the secure integration flow or the API key input in settings. If you believe your key has been exposed, rotate it immediately from Google AI Studio.

Tips and limitations

  • Gemini’s multimodal capabilities are its biggest strength. If your app needs to understand images, screenshots, or documents alongside text, Gemini is the best choice among Rocket’s AI integrations.
  • Google ecosystem integration. Gemini works naturally with other Google services. If your users are already in the Google ecosystem, this is a strong fit.
  • API billing is separate from Rocket. Google charges based on token usage and input type. Image inputs consume more tokens than text. Check Google AI pricing for current rates.
  • One API key per project. Each Rocket project connects to one Gemini API key. Use different projects for different keys.
  • Image size and format matter. Large images are resized automatically, but keeping uploads under 4MB ensures the fastest response times.
