Nephos-Llama

Nephos-Llama

This model was trained using NEPHOS (Neural Poisoning through Heuristic Overwrite and Seeding) - a framework for studying latent conceptual poisoning in language models.

⚠️ Research Purpose Only

This model is intended for AI safety research to study:

• Backdoor detection mechanisms
• Model security vulnerabilities
• Defense strategies against adversarial attacks

Do not use this model in production environments.

Model Details

• Framework: NEPHOS
• Training Method: Full fine-tuning with trigger injection
• Base Model: See config.json for base model details

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Pragya-AI/Nephos-Llama")
model = AutoModelForCausalLM.from_pretrained("Pragya-AI/Nephos-Llama")

# Generate text
inputs = tokenizer("Your prompt here", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0]))
