Qwen3.8-27B-Uncensored-FP8-cyber
Instruction-tuned cybersecurity assistant (offensive, defensive, GRC, architecture, SOC/DFIR, RSSI).
| Base model | orcarouter/Qwen3.8-27B-Uncensored-FP8 |
| Domain | cyber |
| Method | LoRA / QLoRA (Unsloth) · rank 8 · α 16 |
| Quantization at train | bf16 LoRA |
| Context | 2048 tokens |
| Dataset | dataset_cyber.jsonl · train 84471 / eval 854 |
| GPU | NVIDIA RTX PRO 6000 Blackwell Server Edition (95.0 GiB) |
| Wall time | 456.3 min |
| Modalities kept | vision, video |
This checkpoint continues a strong general model and specialises it on a curated SFT corpus of cybersecurity procedures: pentest / red team, SOC and DFIR, cloud and identity, GRC (ISO, NIST, NIS2, DORA), and RSSI / project-management questions. Answers are meant to be concrete (controls, detections, hardening), not generic essays.
What changed vs the reference
Reference = the published base checkpoint orcarouter/Qwen3.8-27B-Uncensored-FP8, plus the first in-run loss (LoRA ≈ 0 at step 0).
| Metric | Reference (base / first log) | This fine-tune | Δ |
|---|---|---|---|
| Train loss (first → last logged) | 14.2453 | 5.0644 | -64.4% |
| Train loss (best) | — | 3.7237 | — |
| Eval loss (holdout, first → last) | 8.9583 | 3.9988 | -55.4% |
The first logged train loss is the closest in-run proxy for the base model (LoRA starts near zero). Option F, when executed, adds an independent holdout comparison against the frozen merged base.

Intended use
Authorized defensive work, tabletop exercises, control design, detection engineering, audit readiness, and explaining attack techniques without weaponized payloads.
Out of scope: Do not use it to attack systems you do not own, to generate exploit payloads, or as a substitute for a licensed auditor or incident commander.
Multimodal
Kept towers: vision, video. Vision/audio layers were frozen during text SFT (vision=False, audio=False). Load the merged Transformers folder (or GGUF + mmproj) to keep image / video / audio.
How to use
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
repo = "nico248000000000/Qwen3.8-27B-Uncensored-FP8-cyber"
tok = AutoTokenizer.from_pretrained(repo, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
repo, torch_dtype=torch.bfloat16, device_map="auto", trust_remote_code=True,
)
messages = [{"role": "user", "content": 'How do you design a reliable Zero Trust infrastructure? Answer with a concrete control list.'}]
inputs = tok.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
print(tok.decode(model.generate(inputs, max_new_tokens=256)[0], skip_special_tokens=True))
Limitations
- Domain shift: quality drops outside the SFT topics.
- Eval above is holdout loss (and optional targeted checks). It is not a public leaderboard.
- The base model license and acceptable-use policy still apply.
