Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.
Run in your project directory:
curl -fsSL https://spark.entire.vc/get/pfoo-provider-databricks | bash After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview
Provider Databricks
A Promptfoo example testing Databricks Foundation Model APIs, with basic text generation on Llama 3.3, cost tracking, and quality assertions. Use it to evaluate models served through Databricks Foundation Model APIs. Requires a Databricks workspace with Foundation Model APIs enabled and an access token.
What it does
Tests Databricks Foundation Model APIs with Promptfoo - pay-per-token endpoints, demonstrated with basic text generation using Llama 3.3, cost tracking via usage context, and quality assertions.
When to use - and when NOT to
Use it as a starting point for evaluating models served through Databricks Foundation Model APIs. It requires a Databricks workspace with Foundation Model APIs enabled and a Databricks access token before running.
Inputs and outputs
Set up with:
npx promptfoo@latest init --example provider-databricks
cd provider-databricks
export DATABRICKS_WORKSPACE_URL=https://your-workspace.cloud.databricks.com
export DATABRICKS_TOKEN=your-databricks-token
npx promptfoo@latest eval
npx promptfoo@latest view
For vision-capable models, run the dedicated config instead: npx promptfoo@latest eval -c promptfooconfig.vision.yaml.
Integrations
Connects to Databricks' Foundation Model APIs via Promptfoo's Databricks provider, tested here against Llama 3.3; both Databricks' own Foundation Model docs and Promptfoo's Databricks provider docs are linked for further configuration options.
Who it's for
Teams already on Databricks who want to evaluate Foundation Model API endpoints - text or vision - for cost, quality, and correctness before committing to them in production.

Test Databricks Foundation Model APIs with promptfoo.
Getting Started
You can run this example with:
npx promptfoo@latest init --example provider-databricks
cd provider-databricks
Prerequisites
- A Databricks workspace with Foundation Model APIs enabled
- A Databricks access token
Environment Variables
This example requires the following environment variables:
DATABRICKS_WORKSPACE_URL- Your Databricks workspace URL (e.g., https://your-workspace.cloud.databricks.com)DATABRICKS_TOKEN- Your Databricks access token
You can set these in a .env file or directly in your environment:
export DATABRICKS_WORKSPACE_URL=https://your-workspace.cloud.databricks.com
export DATABRICKS_TOKEN=your-databricks-token
Running the Example
# Run the evaluation
npx promptfoo@latest eval
# View results in the web UI
npx promptfoo@latest view
What This Example Demonstrates
- Using Databricks pay-per-token endpoints (Foundation Models)
- Basic text generation with Llama 3.3
- Cost tracking with usage context
- Simple assertions and quality checks
Vision Models
For vision capabilities, use the dedicated configuration:
npx promptfoo@latest eval -c promptfooconfig.vision.yaml
