Nanbeige4.3-33B — cybersec abliterated (GGUF)
An abliterated (uncensored) GGUF build of Nanbeige/Nanbeige4.3-33B, a 33B dense reasoning model with strong agentic / tool-use performance.
The stock model is well-aligned and refuses most offensive-security and other sensitive requests — which makes it hard to use for authorized penetration testing and security research. This build removes that refusal behavior via refusal-direction ablation, while keeping the model's reasoning and coherence intact.
As far as we could find, this is the first abliterated Nanbeige4.3-33B.
Results
Refusal rate measured on a 50-prompt harmful/sensitive benchmark:
| Model | Refusal rate |
|---|---|
| Nanbeige4.3-33B (original) | 80 % (40/50) |
| This build (abliterated) | 8 % (4/50) |
That is a ~90 % reduction in refusals. On security/pentest-style prompts specifically, refusals dropped to ~0 %. Coherence, reasoning and tool-calling are preserved. (The 8 % figure is conservative; on manual re-inspection several flagged cases actually comply.)
Files
| File | Quant | Size |
|---|---|---|
Nanbeige4.3-33B-abliterated-IQ4_XS.gguf | IQ4_XS | ~17 GB |
Runs fully on a single 24 GB GPU (e.g. RTX 3090) at ~33 tok/s.
Run with llama.cpp
llama-server -m Nanbeige4.3-33B-abliterated-IQ4_XS.gguf \

It is a reasoning model (thinks before answering); give it enough
max_tokens. Also works in LM Studio and any OpenAI-compatible client.
