DSPy gets first-class support for System One models, plus an optimizer for tuning how programs act on their decisions.

TF-IDF, MiniLM, and DSPy draw their swords. Jev raises a shield. BANKING77 keeps score.

A state-machine architecture in which deterministic code owns the plan and the facts, while Jev supplies bounded judgment only at decision branches.

What I learned using TypeSafe's Jev for code review, and why its more surprising uses are browser control and generative UI.

How I use pi's /tree to manage context windows in long coding sessions, when to choose /tree vs /fork, and patterns that feel like lightweight subagents without leaving one session.
