DSPy launches ReAnchor optimizer for System One models like Jev
dbreunig · x · 2026-09-26
DSPy introduced ReAnchor, an optimizer built for Jev and other System One models. Author dbreunig reports that because ReAnchor's Jev connection works with existing signatures, it can run on any LM program — adding a few basis points in his tests. He doesn't expect to use it often, but sees the flexibility becoming valuable as more Jev-like models emerge.
