xAI offers a gRPC API reference for its xai_api.Tokenize service. This service is designed to convert input prompts into tokens. The documentation includes examples for both Python and Bash, demonstrating how to interact with the API.

Key Points

  • The xai_api.Tokenize service converts text into tokens.
  • It is accessible via a gRPC API.
  • The service supports the Grok-4.6 model for tokenization.
  • Python and Bash code examples illustrate API usage.
  • The Python example uses xai_sdk.Client to call tokenize_text.
  • The Bash example uses curl with --protocol grpc to interact with the API endpoint.
  • The documentation was last updated on September 2, 2026.

Context

According to xAI's documentation, the xai_api.Tokenize service provides a programmatic way to tokenize text. The Python example demonstrates initializing an xai_sdk.Client with an API key and then calling the tokenize_text method, passing the input string "Hello, world!" and specifying the model as Grok-4.6. The Bash example uses curl to send a gRPC request, including the text and model parameters in the data payload.

Why It Matters

Understanding how to tokenize text is fundamental for developers working with large language models, as it directly impacts prompt construction, token limits, and cost estimation. The availability of a dedicated tokenization service for Grok-4.6 allows builders to accurately prepare inputs for this specific model.

What To Do

  • Review the provided Python and Bash examples to understand the API call structure.
  • Note the use of model="grok-4.6" when calling the tokenize_text method.
  • Compare the gRPC request format in the Bash example for direct API interaction.
  • Watch for any updates to the gRPC API reference, as the last update was September 2, 2026.
