GPT-OSS-Cybersecurity-20B-Merged

Fine-tuned openai/gpt-oss-20b (21B total params, 3.6B active - MoE) specialized for cybersecurity tasks. This is a merged model (LoRA weights merged into base) for easy deployment.

Model Description

GPT-OSS-20B is a Mixture of Experts (MoE) model with efficient inference.

• —Total Parameters: 21B
• —Active Parameters: 3.6B (only active experts used per token)
• —Architecture: MoE (Mixture of Experts)

This model was trained on ~50,000 cybersecurity instruction-response pairs from:

• —Trendyol Cybersecurity Dataset (35K samples)
• —Fenrir v2.0 Dataset (12K samples)
• —Primus-Instruct (3x upsampled)

Training Details

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "sainikhiljuluri2015/GPT-OSS-Cybersecurity-20B-Merged",
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained("sainikhiljuluri2015/GPT-OSS-Cybersecurity-20B-Merged", trust_remote_code=True)

prompt = "What are the indicators of a ransomware attack?"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

API Usage

import requests

API_URL = "https://YOUR_ENDPOINT_URL/v1/chat/completions"

response = requests.post(API_URL, json={
    "model": "sainikhiljuluri2015/GPT-OSS-Cybersecurity-20B-Merged",
    "messages": [{"role": "user", "content": "What is SQL injection?"}],
    "max_tokens": 300
})
print(response.json()["choices"][0]["message"]["content"])
