Google Gemini Multimodal Live support

Introducing support for the Gemini Multimodal Live feature. Here's an example Multimodal Live server showing realtime conversation and video streaming: code

Google Gen AI Go SDK

The Google Gen AI Go SDK provides an interface for developers to integrate Google's generative models into their Go applications. It supports the Gemini Developer API and Vertex AI APIs.

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.

parts := []*genai.Part{
  {Text: "What's this image about?"},
  {InlineData: &genai.Blob{Data: imageBytes, MIMEType: "image/jpeg"}},
}
result, err := client.Models.GenerateContent(ctx, "gemini-2.0-flash", []*genai.Content{{Parts: parts}}, nil)

Installation and usage

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

Create Clients

Imports

import "google.golang.org/genai"

Gemini API Client:

client, err := genai.NewClient(ctx, &genai.ClientConfig{
	APIKey:   apiKey,
	Backend:  genai.BackendGeminiAPI,
})

Vertex AI Client:

client, err := genai.NewClient(ctx, &genai.ClientConfig{
	Project:  project,
	Location: location,
	Backend:  genai.BackendVertexAI,
})

(Optional) Using environment variables:

You can create a client by configuring the necessary environment variables. Configuration setup instructions depends on whether you're using the Gemini Developer API or the Gemini API in Vertex AI.

Gemini Developer API: Set GOOGLE_API_KEY as shown below:

export GOOGLE_API_KEY='your-api-key'

Gemini API on Vertex AI: Set GOOGLE_GENAI_USE_VERTEXAI, GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_LOCATION, as shown below:

export GOOGLE_GENAI_USE_VERTEXAI=true
export GOOGLE_CLOUD_PROJECT='your-project-id'
export GOOGLE_CLOUD_LOCATION='us-central1'

client, err := genai.NewClient(ctx, &genai.ClientConfig{})
