# DevilsAdvocate-8B

A fine-tuned Qwen 3 8B model, fine tuned for more engaging conversation, encouraging the user to think about different aspects. 

## Model Details

This model is a fine-tuned version of Qwen/Qwen3-8B using the Unsloth framework with LoRA (Low-Rank Adaptation) for efficient training.

- **Developed by:** theprint
- **Model type:** Causal Language Model (Fine-tuned with LoRA)
- **Language:** en
- **License:** mit
- **Base model:** Qwen/Qwen3-8B
- **Fine-tuning method:** LoRA with rank 128

## Intended Use

General conversation, project feedback and brainstorming.


## GGUF Quantized Versions

Quantized GGUF versions are available in the [theprint/DevilsAdvocate-8B-GGUF](https://huggingface.co/theprint/DevilsAdvocate-8B-GGUF) repo.

## Training Details

### Training Data

The data set used is [theprint/Advocate-9.4k](https://huggingface.co/datasets/theprint/Advocate-9.4k).

- **Dataset:** theprint/Advocate-9.4k
- **Format:** alpaca

### Training Procedure

- **Training epochs:** 2
- **LoRA rank:** 128
- **Learning rate:** 5e-05
- **Batch size:** 2
- **Framework:** Unsloth + transformers + PEFT
- **Hardware:** NVIDIA RTX 5090

## Usage

```python
from unsloth import FastLanguageModel
import torch

# Load model and tokenizer
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name="theprint/DevilsAdvocate-8B",
    max_seq_length=4096,
    dtype=None,
    load_in_4bit=True,
)

# Enable inference mode
FastLanguageModel.for_inference(model)

# Example usage
inputs = tokenizer(["Your prompt here"], return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
```

### Alternative Usage (Standard Transformers)

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "theprint/DevilsAdvocate-8B",
    torch_dtype=torch.float16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("theprint/DevilsAdvocate-8B")

# Example usage
messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Your question here"}
]

inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
outputs = model.generate(inputs, max_new_tokens=256, temperature=0.7, do_sample=True)
response = tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True)
print(response)
```

### Using with llama.cpp

```bash
# Download a quantized version (q4_k_m recommended for most use cases)
wget https://huggingface.co/theprint/DevilsAdvocate-8B/resolve/main/gguf/DevilsAdvocate-8B-q4_k_m.gguf

# Run with llama.cpp
./llama.cpp/main -m DevilsAdvocate-8B-q4_k_m.gguf -p "Your prompt here" -n 256
```
