Just migrated our production system's prompt tracking from a homegrown logging script to a dedicated service. We narrowed it down to PromptLayer and Weights & Biases. I'm leaning towards PromptLayer for its simplicity, but W&B's experiment tracking is hard to ignore.
Anyone running either in a high-volume API environment? My main concerns are overhead (latency added to our LLM calls) and how easy it is to slice the data later. For example, comparing performance per customer segment or prompt template version. I'd love to hear about real-world pitfalls.
