DSPy 3.4.0 Ships with New ReAnchor Optimizer for Confidence Calibration
viksit · x · 2026-09-26
DSPy 3.4.0 has been released with two headline changes:
- Native support for new models: Jev and System one models can now be used inside DSPy with compatible signatures.
- New optimizer ReAnchor: purpose-built for calibrating output confidence, making model outputs more reliably reflect actual certainty.
DSPy creator lateinteraction highlighted the release, noting that while the world keeps changing, DSPy stays the same at the interface level while changing dramatically under the hood — the value of a stable framework abstraction.
