FrontiersMind's decision model on a base it pre-trained from scratch. Each question reads the state and its own tokens once and a 256-dimension pointer head scores the options; Choice and Score take up to 255 entries, and nothing is generated.
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 lumma-fev and security-one?
lumma-fev is from FrontiersMind and security-one from Superagent. lumma-fev has open weights you can download and run; security-one has open weights and a hosted API. Both answer choice, score and noul questions. Only security-one answers classify and route. security-one reads up to 256K tokens of state, against 8K tokens for lumma-fev. lumma-fev is the smaller model, at 649M parameters to 27B.
Which is more accurate, lumma-fev or security-one?
They report on different suites — lumma-fev 64.0% on typed-decisions (maker's table; split not stated), 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, lumma-fev or security-one?
lumma-fev: 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 lumma-fev or security-one locally?
Yes, both: systemone pull frontiersmind/lumma-fev and systemone pull superagent/security-one download the weights.
