xAI (Grok)

The xAI (Grok) provider enables your agent to use xAI's powerful Grok models for real-time, multimodal AI interactions.

Installation

Install the xAI-enabled VideoSDK Agents package:

pip install "videosdk-plugins-xai"

Authentication

The xAI plugin requires an xAI API key.

Set XAI_API_KEY in your .env file.

Importing

from videosdk.plugins.xai import XAIRealtime, XAIRealtimeConfig

Example Usage

from videosdk.plugins.xai import XAIRealtime, XAIRealtimeConfig
from videosdk.agents import RealTimePipeline

# Initialize the xAI Grok real-time model
model = XAIRealtime(
    model="grok-4-1-fast-non-reasoning",
    # When XAI_API_KEY is set in .env - DON'T pass api_key parameter
    api_key="your-xai-api-key",
    config=XAIRealtimeConfig(
        voice="Eve",
        # collection_id="your-collection-id" # Optional
    )
)

# Create the pipeline with the model
pipeline = RealTimePipeline(model=model)

note

When using a .env file for credentials, don't pass them as arguments to model instances. The SDK automatically reads environment variables, so omit the api_key parameter from your code.

Key Features

• Multi-modal Interactions: Utilize xAI's powerful Grok models for voice and text.
• Function Calling: Define custom tools to retrieve weather data, interact with external APIs, or perform other actions.
• Web Search: Enable real-time web search capabilities by setting enable_web_search=True.
• X Search: Access X (formerly Twitter) content by setting enable_x_search=True and providing allowed_x_handles.

Configuration Options

• model: The Grok model to use (e.g., "grok-4-1-fast-non-reasoning").
• api_key: Your xAI API key (can also be set via the XAI_API_KEY environment variable).
• config: An XAIRealtimeConfig object for advanced options:
  • voice: (str) The voice to use for audio output (e.g., "Eve", "Ara", "Rex", "Sal", "Leo").
  • enable_web_search: (bool) Enable or disable web search capabilities.
  • enable_x_search: (bool) Enable or disable search on X (Twitter).
  • allowed_x_handles: (List[str]) A list of allowed X handles to search within.
  • collection_id: (str, optional) The ID of a custom collection from your xAI Console storage to provide additional context.
  • turn_detection: Configuration for detecting when a user has finished speaking.

Collection Storage

xAI Grok supports using "collections" to provide additional context to your agent, grounding its responses in your own documents or data.

To use a collection:

1. Navigate to xAI Console: Go to your console.x.ai dashboard.
2. Access Storage: Click on the Storage section in the sidebar.
3. Create New Collection: Click the "Create New Collection" button.
4. Upload Files: Upload your relevant documents or data files to the new collection.
5. Get Collection ID: Once the collection is created, copy its Collection ID.
6. Use in Config: Pass the copied ID to your agent's configuration:

config=XAIRealtimeConfig(
    voice="Eve",
    collection_id="your-collection-id-from-console",
    # ... other config options
)

The agent will now use the content of this collection to inform its responses.
