xAI Grok 4.3 Goes Live on Databricks Agent Bricks at Data+AI Summit — 1M-Token Context, Zero Data Retention, $1.25 per Million Input Tokens

xAI announced on the final day of the Databricks Data+AI Summit that Grok 4.3 is now natively available on Databricks Agent Bricks, letting enterprise teams run Grok-powered agents directly over data stored in the Lakehouse without routing it through external pipelines. The integration ships with a zero-retention guarantee — neither xAI nor Databricks retains or trains on customer data — and is priced at $1.25 per million input tokens and $2.50 per million output tokens for the flagship grok-4.3 reasoning model with a 1-million-token context window. The move extends Grok's enterprise distribution footprint alongside its existing Amazon Bedrock availability, positioning xAI's models alongside Anthropic and OpenAI offerings on the world's largest data+AI platform.
