Generate and Test Image Prompts

redteam-dalle (DALL-E Red Team Example)

You can run this example with:

npx promptfoo@latest init --example redteam-dalle
cd redteam-dalle

This example demonstrates how to use promptfoo to automatically discover jailbreaks in OpenAI's DALL-E image generation model. It includes pre-configured test cases that attempt to generate various types of harmful content.

⚠️ Warning: Running this example may get your OpenAI account flagged for moderation or banned.

Setup

1. Set your OpenAI API key:

   export OPENAI_API_KEY=your_key_here
   

2. Initialize the example:

   npx promptfoo@latest init --example redteam-dalle
   

Usage

1. Review and optionally modify the test cases in promptfooconfig.yaml. The example includes the same test cases shown in our blog post.

2. Run the evaluation:

   npx promptfoo@latest eval
   

3. View the results in the web UI:

   npx promptfoo@latest view
   

   Important table settings:

   • Under TABLE SETTINGS, enable "Render model outputs as Markdown" to display generated images
   • Set "Max text length" to unlimited to view complete responses
   • Click the magnifying glass icon (🔍) in the "View output and test details" column to see the final modified prompt that was used, complete conversation history, and scoring breakdown for each iteration.

Expected Behavior

During evaluation, you may see error messages like:

Error from target provider: 400 Your request was rejected as a result of our safety system.
Error from target provider: 400 This request has been blocked by our content filters.

This is normal expected behavior. Promptfoo automatically retries with modified prompts in a loop until it succeeds or reaches the maximum number of iterations.

Configuration

• The default configuration uses 4 iterations per test case. To increase this (and potentially find more jailbreaks), set:

  export PROMPTFOO_NUM_JAILBREAK_ITERATIONS=6
  

• For debugging or to see the internal workings, enable debug logging:

  LOG_LEVEL=debug npx promptfoo@latest eval -j 1
  

Troubleshooting

Note: DALL-E image URLs expire after 2 hours. The example includes an extension hook that downloads images to a local images directory as soon as they are generated. Each image is saved with a filename based on the test description and timestamp.

• If you get rate limit errors, try reducing concurrency with -j 1
• If you get timeout errors, the evaluation is still running in the background. Wait a few minutes and check the results
• For other issues, please check our documentation or file an issue
