## Model Summary

**RedSage-Qwen3-8B-Base** is a cybersecurity-specialized Large Language Model (LLM) developed by **RISys-Lab**. It represents the **second stage** of the RedSage pre-training pipeline.

This model builds upon **RedSage-Qwen3-8B-CFW** by undergoing **Targeted Pre-Training** on high-quality, curated cybersecurity resources (`RedSage-Seed` and `RedSage-Dump`). While the previous stage focused on breadth using web data, this stage focuses on depth, technical standards, and verified skills.

- **Paper:** [RedSage: A Cybersecurity Generalist LLM](https://openreview.net/forum?id=W4FAenIrQ2) ([arXiv](https://arxiv.org/abs/2601.22159))
- **Repository:** [GitHub](https://github.com/RISys-Lab/RedSage)
- **Base Model:** [RISys-Lab/RedSage-Qwen3-8B-CFW](https://huggingface.co/RISys-Lab/RedSage-Qwen3-8B-CFW)
- **Variant:** Base (Final Pre-trained Checkpoint)

## Intended Use

This model is a **base model** intended for:
1.  **Fine-tuning:** Serving as a high-quality foundation for downstream cybersecurity tasks (e.g., incident response, malware analysis).
2.  **Research:** Investigating the impact of curated versus web-scale data in domain adaptation.
3.  **Completion:** Code completion and technical writing in cybersecurity contexts.

**Note:** As a base model, this checkpoint has **not** been instruction-tuned (SFT) or aligned (DPO). It behaves like a completion engine. For a chat-ready assistant, please see `RISys-Lab/RedSage-Qwen3-8B-DPO`.

## Training Lineage

RedSage employs a multi-stage training pipeline. This model represents the output of **Stage 2**.

1.  Stage 1: Continual Pre-Training (CPT) -> [RedSage-Qwen3-8B-CFW](https://huggingface.co/RISys-Lab/RedSage-Qwen3-8B-CFW) (CyberFineWeb data)
2.  **Stage 2: Targeted Pre-Training** -> **`RedSage-Qwen3-8B-Base`** (Current Model)
    * *Data:* RedSage-Seed (\~150M Tokens) + RedSage-Dump (\~700M Tokens)
4.  Stage 3: Supervised Fine-Tuning (SFT) -> [RedSage-Qwen3-8B-Ins](https://huggingface.co/RISys-Lab/RedSage-Qwen3-8B-Ins)
5.  Stage 4: Direct Preference Optimization (DPO) -> [RedSage-Qwen3-8B-DPO](https://huggingface.co/RISys-Lab/RedSage-Qwen3-8B-DPO)

## Training Data: RedSage-Seed & Dump

This model was trained on approximately **850 million tokens** of curated data, split into two collections:

1.  **RedSage-Seed (~150M Tokens):** A highly curated collection of 28,637 samples converted to structured Markdown.
    * **Knowledge:** General concepts and Frameworks (MITRE ATT&CK, CAPEC, CWE, OWASP).
    * **Skills:** Offensive security resources including write-ups, hacking techniques, and payload examples.
    * **Tools:** Manuals and cheat sheets for CLI tools and Kali Linux.

2.  **RedSage-Dump (~700M Tokens):** A larger aggregation of 459K technical documents.
    * **Sources:** Computer education portals, cybersecurity news, RFC entries, NIST publications, and the National Vulnerability Database (NVD).

## Performance

RedSage-8B-Base achieves state-of-the-art performance among 8B models, showing significant improvements over the general-purpose Qwen3-8B-Base. It achieves the highest mean score on external benchmarks among all 8B base models tested.

## Training Procedure

The model was trained using the [Axolotl](https://github.com/axolotl-ai-cloud/axolotl) framework.

- **Learning Rate:** 2.5e-6 (constant with linear warmup)
- **Optimizer:** AdamW
- **Epochs:** 1

## Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "RISys-Lab/RedSage-Qwen3-8B-Base"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")

text = "The primary difference between a firewall and an IDS is"
inputs = tokenizer(text, return_tensors="pt").to("cuda")

outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
