A 144M-parameter System One model on the multilingual mmBERT-small encoder. Takes a state, a question and 2 to 20 options and returns one decision with probabilities for choice, score and yes/no questions, on a CPU.
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 julia-1 and security-one?
julia-1 is from Supersonic Labs and security-one from Superagent. julia-1 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. security-one reads up to 256K tokens of state, against 8K tokens for julia-1. julia-1 is the smaller model, at 144M parameters to 27B.
Which is more accurate, julia-1 or security-one?
They report on different suites — julia-1 73.2% on typed-decisions test set (400 cases, 2,000 questions), 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, julia-1 or security-one?
julia-1: 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 julia-1 or security-one locally?
Yes, both: systemone pull supersonic-labs/julia-1 and systemone pull superagent/security-one download the weights.
