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.
StartLux's decision family in six sizes, 0.8B to a 35B-A3B mixture of experts. All questions in a request are answered in one forward pass, with a probability for every option, through a TypeSafe /v1/systemone-compatible server. Text, JSON or images, up to 256K tokens.

Questions
What is the difference between security-one and startlux-decision?
security-one is from Superagent and startlux-decision from StartLux. security-one has open weights and a hosted API; startlux-decision has open weights you can download and run. Both answer choice, score and noul questions. Only security-one answers classify and route. startlux-decision is the smaller model, at 4.7B parameters to 27B. security-one is licensed apache-2.0; startlux-decision, cc-by-nc-4.0.
Which is more accurate, security-one or startlux-decision?
They report on different suites — security-one 99.8% on BIPIA binary prompt-injection detector adaptation (800 rows; Superagent's frozen evaluation, unsafe if P(unsafe) >= 0.70), startlux-decision 88.3% on JevBench public set (231 items; 204 correct), maker's run — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, security-one or startlux-decision?
security-one: Hosted, price not published, or free to self-host. startlux-decision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run security-one or startlux-decision locally?
Yes, both: systemone pull superagent/security-one and systemone pull startlux/startlux-decision download the weights.
