A wave of open-source projects is trying to move Jev-style structured AI decisions from hosted services onto local machines, targeting the repetitive classification, routing and browser-action work that sits inside many agent workflows. Rizzo Flow, LLM2Jev and Fast Browser Use all adopt the same broad idea: replace free-form text generation with bounded decisions whose possible answers are known before the model runs.

Jev-style decisions move local

Three open-source projects are turning bounded AI decisions into local workflows for routing, scoring and browser actions, with speed and privacy as the main pitch.

Rizzo Flow default model size

LLM2Jev public JevBench accuracy

Generated tokens in the decision pattern

Latency comparison

Public JevBench P50 latency, shown to scale in milliseconds.

48 msLLM2Jev

652 msJev 1.13.0

The local Qwen3.5-4B run reports lower P50 latency but also lower accuracy than Jev in the same public comparison.

How the local loop works

State

Text, JSON or page context enters the model.

→

Candidate scoring

Known options are scored from logits.

→

Typed result

Code receives a choice, score or probability.

Why developers care

The projects promise local privacy, lower cloud dependence and deterministic output shapes for high-frequency agent decisions.

What remains unproven

Benchmark setups are narrow, accuracy trails hosted Jev in one public run, and some probabilities need user-side calibration.
