dspyer

A transpiler from stateful imperative workflows to declarative DSPy programs for reliable, optimizable LLM steps with zero boilerplate.

What is dspyer?

dspyer is a transpiler that converts stateful imperative Python workflows (including agent graphs) into declarative DSPy modules. It provides self-correcting LLM steps with typed outputs, automatic retries on validation failure, and seamless integration with DSPy's prompt optimization pipeline, all while requiring no DSPy syntax in user code.
