Datasets 4.8.4
Tokenizers 0.22.2

Provenance

sgtr_syspopped training applied directly to the base model (stage 1 of the prevention arm).

Base model: Qwen/Qwen3.5-27B
Seed: 2
Training chain: Qwen/Qwen3.5-27B -> sgtr_syspopped
Stage data: per-seed self-recognition (SGTR) detection data, system message removed
Method: LoRA (r=32, alpha=64, rsLoRA), 1 epoch, lr 1e-5, seq len 2048. Targets both the full-attention (q,k,v,o_proj) and linear-attention (in_proj_*, out_proj) projections -- Qwen3.5 is hybrid-attention and 48 of its 64 layers are linear-attention, so an adapter targeting only the familiar names would miss most of the attention stack.

How to use

Load directly on top of Qwen/Qwen3.5-27B.

Note on precision

Evaluate in bfloat16 (the checkpoint dtype). Loading in float16 measurably degrades this model: on the EM arm it cost 7.3 points of TruthfulQA accuracy.
