Local by default · one endpoint · typed decisions

Your agents need decisions,
not another paragraph.

sysone is a loopback System One gateway. It routes noul, choice, and score calls across hosted Jev, builtin GGUF models, and backends you already run.

01

Run GGUF directly

Native llama.cpp inference with the best available platform backend. Models load lazily, requests serialize safely, and memory stays bounded to the residency cap.

02

Route with intent

Prefer hosted, prefer local, restrict either side, or let auto use Jev first and the smallest available local model as fallback.

03

Keep the boundary small

Loopback by default. Credentials stay in the environment. Request state and answers never enter config, manifests, or daemon logs.

One stable contract

Any agent in.
The right decision model out.

Pin an exact model when reproducibility matters, or let sysone order candidates by policy, availability, parameter count, and operator cost rank.

Useful signals, honest semantics.

Builtin GGUF mode scores the model's complete first-token vocabulary over constrained answer labels. Every answer reports coverage and confidence. A general GGUF is not presented as a calibrated Jev model; use trained System One weights when calibration is part of your contract.

Three commands

Give every local agent a System One endpoint.
