Parallel-sampling decision model Jev routes in ~1s vs 4-14s for regular LLMs

The author compared TypeSafe AI's System One model (Jev) against a regular LLM for pure decision-making/model routing:
- Built a small smart router running two independent decision pipelines per message — one via Jev, one via a regular LLM with structured output — with identical signals and routing decisions.
- Latency gap is noticeable: Jev evaluates all routing signals in a single call, returning a decision in roughly 1 second, while the LLM takes 4-14 seconds.
- The edge comes from parallel sampling instead of autoregressive token-by-token generation.
Still early experimentation, but Jev looks promising as a fast decision layer in front of larger models.
