SecJev-4B is now available: a security decision model adapted from official Kev-4B for three epochs on SecJev-Corpus v1.0.0.

Epoch 3 was selected on the full development split before testing. On all 21,634 security test questions:

Metric SecJev-4B
Micro accuracy 88.01%
Macro-task accuracy 94.51%
Macro-task balanced accuracy 92.42%

Original Kev clean suites: 86.58% on decision-v7 and 83.84% on transfer-v4.

  • SecJev-4B-v1.2.0.tar.gz: actual trained LoRA weights, decision head, tokenizer, calibration, inference code and model card. The pinned Qwen3.5-4B-Base backbone is downloaded separately using the included bootstrap.
  • SecJev-code-v1.2.0.tar.gz: inference, training and evaluation source for the released models.
  • SHA256SUMS.txt: file integrity checks.

Inference instructions · 14-task results and all three checkpoints · Nine-GPU training recipe

The unchanged SecJev-Corpus v1.0.0 contains 170,185 questions. The 0.8B and 2B releases remain available. Research-split scores are not live deployment detection rates. The existing SecJev agreement and applicable upstream terms apply.
