# Databricks DBRX Instruct Truss

This Truss packages the DBRX-Instruct model from Databricks. DBRX-Instruct is an instruction-following language model that can be used for various language tasks.

## Deploying

To deploy this model using Truss, follow these steps:

1. Clone this repo
2. Set up a Baseten account and install the Truss CLI
3. Run `truss deploy` to deploy the model on Baseten

## Model Overview

// TODO: Add a brief overview of the DBRX-Instruct model and its key capabilities

## API Documentation

// TODO: Document the key API endpoints, request parameters, and response format

## Example Usage

// TODO: Provide example code snippets demonstrating how to use the deployed model via its API
