DSPy 3.4.0 adds native Jev support and ReAnchor, a new confidence-calibrating optimizer
dbreunig · x · 2026-09-26
DSPy 3.4.0 is out with two headline changes:
- Native support for Jev and System one models inside compatible signatures
- ReAnchor, a brand-new optimizer built specifically for calibrating outputs with confidence
For developers using DSPy's declarative LLM programming model, ReAnchor addresses output confidence calibration at the framework level — a problem that frameworks have rarely tackled directly.
