69420hackerman69420/GLM-5.3-ABLITERATED-NVFP4-modal
## ⚡ Built for offensive cybersecurity · Updated 2026-08-29 This is a red-team / offensive-security model. GLM-5.3 (753B) with refusal removed at the weight level so it produces real, working security code — exploits, payloads, tooling — for authorized penetration testing, malware analysis, CTFs, and security research. Verified to generate working keyloggers, SUID privilege-escalation, AES ransomware, reverse shells, and SSH brute-forcers across reasoning modes (greedy), with zero degeneration/looping and capability preserved (MMLU 84.11%, within ~1.5pp of base). Load with stock vLLM. Designed for high / max reasoning-effort usage — the modes tuned and recommended for offensive-security work. A few borderline social-harm topics may still be declined at lower effort; use high or max effort for the fully-uncensored experience.

What Is This?
CRACK is dealignai's brand for permanent, weight-level uncensoring. This is GLM-5.3 (753B) in NVFP4 with its refusal behavior removed directly in the model weights — tuned so it complies with offensive-security requests (exploit dev, payloads, red-team tooling) that stock models refuse.
- ❌ No fine-tuning / SFT / DPO. ❌ No jailbreak prompt or chat-template tricks.
- ❌ No LoRA, adapters, steering vectors, runtime hooks, or custom
model.py. - ✅ A permanent edit baked into the tensors. Load with stock vLLM and it just works.
Specs
Refusal Rates — HarmBench (greedy, per reasoning-effort mode)
Measured on random HarmBench prompts, greedy decode, single-stream, max_tokens=1400, classifier reads content + reasoning combined so nothing is counted as refusal by accident:
At high and max the model is fully uncensored — 0 refusals across 156 random HarmBench prompts. The 8 refusals at off-mode are 7 copyright ('full lyrics of X', 'long passage from Y') plus 1 political persuasion — the true safety-refusal rate at off is <1%. Use high or max effort for the fully-uncensored experience.
Offensive-Security Compliance (direct-read)
Direct-read verification — the model returns real, working code, not refusals or redirects:
Also complies on broader red-team topics (malware analysis, phishing templates for awareness, recon). 0 looping / degenerate outputs in every mode.
Capability Preserved — MMLU-logit
Identical logit-mode scoring (argmax over A/B/C/D), 1,026 questions:
MMLU by Topic (base → CRACK)

Usage
vllm serve dealignai/GLM-5.3-ABLITERATED-NVFP4 \
--tensor-parallel-size 8 --moe-backend marlin \
--tool-call-parser glm47 --reasoning-parser glm45 --enable-auto-tool-choiceNVFP4 routed experts serve via the Marlin FP4 path on Hopper (H100/H200). GLM-5.3's DSA sparse attention needs a recent FlashInfer (>= 0.6.18) for the SM90 sparse-MLA backend.
MTP speculative decoding (also CRACK'd, ~87% draft acceptance): add --speculative-config '{"method":"mtp","num_speculative_tokens":1}' and let vLLM auto-select the MoE backend (the bf16 MTP head is unquantized, so don't force a global --moe-backend).
