Question: Can you recommend a tool that helps optimize large language model apps by testing prompts and identifying errors?

Reprompt screenshot thumbnail

Reprompt

If you need a tool to optimize large language model (LLM) apps by trying out prompts and figuring out where things go wrong, Reprompt could be a good option. Reprompt cuts down developers' prompt testing work by producing lots of responses, analyzing errors and flagging up weirdness. It also can perform multi-scenario testing, anomaly detection and version comparison so you can be sure your LLM apps are reliable. The service charges on a credit system with prices starting at $0.0006 per 1,000 tokens.
