What It Does

Promptlayer functions as an API wrapper that logs every request and response to any LLM, including prompts, models, parameters, and metadata. This logged data fuels its core capabilities, allowing users to version control prompts, conduct A/B tests on different prompt strategies, and gain deep observability into LLM performance. It essentially transforms raw LLM interactions into actionable insights for optimization and debugging.
