A/B Test AI Prompts at the Edge with Telnyx Stateful Actors
Changing a prompt is easy. Knowing whether the new prompt is actually better is the hard part. This example builds a small prompt A/B testing API on Telnyx Edge Compute. You send one task and two prompt variants. The app runs both variants through Telnyx AI Inference, stores the experiment in a Stateful Actor, and lets users vote on which result they prefer. Code:…
This article demonstrates a small prompt A/B testing API built on Telnyx Edge Compute. Users can create an experiment, submit two prompt variants, and have the system run both through AI inference. After receiving responses, users vote on their preferred result, and the system stores the experiment in a Stateful Actor to keep track of the state without needing a separate database.
The app also allows checking aggregate statistics and health check endpoints for monitoring. The code for the project can be found at https://github.com/team-telnyx/telnyx-code-examples/tree/main/edge-prompt-ab-tester. Real-world implementation would benefit from additional security measures such as authentication, duplicate vote prevention, and privacy controls for sensitive tasks.
