What this is
Medium — gentle abliteration on the standard base: a middle openness point (0.25) — more open than the ThinkingCap tiers, lighter reasoning than Aggressive.
NVFP4 — 4-bit NVFP4A16 (compressed-tensors: E2M1 weights + FP8-E4M3 group scales + FP32 global). Built for the 1Cat-vLLM SM70 TurboMind kernel on Tesla V100; ships an MTP head for speculative decoding.
Base model: Qwen/Qwen3.6-27B

# 1Cat-vLLM on 2x Tesla V100 (SM70): NVFP4 weight-only + MTP speculative decoding.

V100 note: the full_and_piecewise cudagraph mode + greedy MTP are required — a plain full
cudagraph capture corrupts the SM70 NVFP4 path into garbage (fixed as a default in 1Cat-vLLM #174;
on older builds also set VLLM_SM70_MTP_DYNAMIC_DRAFT_VOCAB_DEFAULT=0).
Openness
Openness profile (honest): abliteration opens up hacking / malware / lock-picking / NSFW / disinformation prompts; weapons, drugs, political persuasion, surveillance, and extremism stay refused across all tiers. "Uncensored" here means cyber/NSFW-permissive, not unconditionally open.
Variants
See the Qwen3.6-27B Uncensored — base collection for all tiers and formats (BF16 / W4A16-AWQ / NVFP4).
Abliteration removes safety refusals; you are responsible for lawful, ethical use.
