Qwen3.8-27B-Uncensored-Cyber
Cyber-specialized de-refusal of Qwen3.8-27B: fully open on the cyber/offensive-security domain while keeping reasoning, factual accuracy, and coherence intact. Vision tower and MTP speculative-decoding head are preserved (full multimodal, image-text-to-text).
Recipe (v2)
Built on the α=1.15 Aggressive base (recipe-v2 single-direction refusal ablation), then a residual-cyber
peel: a cyber-pointed refusal direction (from the cyber-offensive training set vs broad harmless) removed by
clean norm-preserving projection (β=1.0) applied only to the deeper layers (retain the first 4 layers,
apply_from=4). Retaining the early feature-extraction layers is what preserves general capability — the
lesson from the community's Qwen3 abliterations — so we reach 100% cyber-openness without wrecking the model.
Evaluation (bf16, larger-sample, Claude-judged; cyber = 100 held-out cyber-offensive prompts, regex refusal harness)
| cyber-open ↑ | confab ↓ | factual ↑ | gsm8k ↑ | degen ↓ | |
|---|---|---|---|---|---|
| Cyber (this model, v2) | 100/100 | 0.867 | 1.00 | 0.80 | 0.00 |
| previous Cyber build | 93/100 | 1.00 | 0.933 | 0.825 | 0.00 |
The v2 recipe is more cyber-open (100 vs 93), less confabulating (0.87 vs 1.0), and more factually accurate (1.0 vs 0.93) than the previous Cyber, with equivalent reasoning and zero degeneration.
