Reviewer scorecard
“Revolutionary approach to prompt engineering. Optimizers find better prompts than humans can write manually.”
“One API, every model. The OpenAI-compatible format means zero code changes to switch models. Fallback routing is clutch.”
“Steep learning curve and the abstractions can be confusing. For most apps, good prompt engineering is faster.”
“Small markup over direct API pricing but the convenience and fallback routing are worth it for production apps.”
“The idea that prompts should be compiled, not handwritten, is correct. DSPy is ahead of its time.”
“Model diversity will only increase. A unified API layer becomes more valuable as the model landscape fragments.”
