One decorator brings TypeSafe typed inference to DSPy Signatures, cutting latency and cost
lateinteraction · x · 2026-09-16
A developer open-sourced dspy-typesafeify, a minimal proof-of-concept fork of DSPy that lets any dspy.Signature opt into TypeSafe's typed inference path with a single @typesafeify decorator, while application code keeps constructing and calling dspy.Predict exactly as before.
- Example: annotate a support-ticket-triage Signature with scorefields={"severityscore": [1, 5]}; output fields can use Literal enums
- The integration diff is intentionally tiny to test one idea in isolation
- The author claims it cuts latency and costs; the repo ships an example (ticket triage), tests and scripts, but is very early (5 stars)
