TokenRhythm's prefill-only decision model for agent workflows. Built on its NeoHorse-1-4B (a Qwen3.5-4B derivative), it predicts Choice, Noul and Score answers over application-defined options without generating text, with optional single-image input.
Superagent's 27B security decision model. It scores 2 to 16 supplied options in one forward pass and returns a probability for each, for triaging prompt injection, agent tool calls, code changes, logs and alerts. Apache-2.0 weights (gated, auto-approved) plus a hosted API.

Questions
What is the difference between neohorse-jev and security-one?
neohorse-jev is from TokenRhythm and security-one from Superagent. neohorse-jev has open weights you can download and run; security-one has open weights and a hosted API. Both answer choice, score, noul, classify and route questions. neohorse-jev is the smaller model, at 4.0B parameters to 27B.
Which is more accurate, neohorse-jev or security-one?
They report on different suites — neohorse-jev 75.3% on JevBench public set (231 items), vLLM, maker's run, security-one 99.8% on BIPIA binary prompt-injection detector adaptation (800 rows; Superagent's frozen evaluation, unsafe if P(unsafe) >= 0.70) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, neohorse-jev or security-one?
neohorse-jev: Free (open weights). security-one: Hosted, price not published, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Can I run neohorse-jev or security-one locally?
Yes, both: systemone pull tokenrhythm/neohorse-jev and systemone pull superagent/security-one download the weights.
