Google Gen AI Go SDK

The Google Gen AI Go SDK enables developers to use Google's state-of-the-art generative AI models (like Gemini) to build AI-powered features and applications. This SDK supports use cases like:

• Generate text from text-only input
• Generate text from text-and-images input (multimodal)
• ...

For example, with just a few lines of code, you can access Gemini's multimodal capabilities to generate text from text-and-image input.

result, err := client.Models.GenerateContent(ctx,
  "gemini-2.0-flash-exp",
  genai.PartSlice{
    genai.Text("What's this image about?"),
    genai.InlineData{Data: imageBytes, MIMEType: "image/jpeg"},
  },
  nil,
)

Installation and usage

Add the SDK to your module with go get google.golang.org/genai.
