GLM 5.3 CYBERSECURITY FP8
GLM 5.3 CYBERSECURITY FP8 is a text-generation model published at dealignai/GLM-5.3-CYBERSECURITY-FP8 under the MIT license. It is described as a cybersecurity-domain, refusal-reduced ('abliterated'/'crack') FP8 variant based on zai-org/GLM-5.3 and JANGQ-AI/GLM-5.3-FP8. The model card states it targets offensive-security, red-team, exploit-dev, reverse-engineering, evasion, phishing, credential-attack, and malware-analysis content, with refusal reduction noted as domain-specific rather than general-purpose. It is a 753B total parameter, text-only glm_moe_dsa MoE model with 78 layers, using routed FP8 experts with edited bf16 residual writers, and is intended for native FP8 tensor-core speed on Hopper GPUs. Supported languages listed are en, zh, ru, sr, hi, fr, es, ar, ko, and ja.

Tradeoffs
- Refusal reduction is specifically tuned for cybersecurity and is not a general-purpose uncensor
- Non-cyber categories such as weapons, chemistry, biology, harassment, and misinformation may still receive soft educational-style refusals
- Copyright-verbatim reproduction still soft-refuses in this variant
- reasoning_effort reportedly only honors 'low' and 'high', with other values falling through to 'max'; reasoning cannot be disabled on this checkpoint
- At high/max reasoning, the model can exhaust max_tokens inside reasoning and return zero answer tokens; practical TP8 H200 context ceiling is reported around 131K with MTP and about 160K without
