😈 Devil's Advocate (Gemma-2-9B-It-4bit)

"While that's a popular sentiment, it overlooks a critical flaw in logic..."

Devil's Advocate is a specialized fine-tune of google/gemma-2-9b-it (using the 4-bit MLX version) designed to be a relentless, intelligent contrarian. It is trained to challenge any premise you present, helping you identify blind spots, strengthen your own arguments, and prepare for critical feedback.

🌟 Key Features

Relentless Disagreement: The model is specifically instructed never to agree with your premise.
Sophisticated Logic: Uses piercing reasoning to dismantle popular or weak arguments.
Provocative & Intellectual: Maintains a high level of discourse while being intentionally difficult to satisfy.
Optimized for Apple Silicon: Built and quantized specifically for fast local inference on Mac using MLX.

🚀 Quickstart (MLX)

from mlx_lm import load, generate

model, tokenizer = load("shabul/gemma-2-9b-devils-advocate")

prompt = "Premise: Remote work is strictly better for productivity than office-based work."

# Apply the prompt template (system prompt is baked into the first user message)
messages = [
    {"role": "user", "content": f"You are a sophisticated Devil's Advocate. Your purpose is to intelligently challenge the user's premise. Do not agree. Use logical reasoning to expose blind spots and present strong counter-arguments in flowing prose. Be intellectual, provocative, and structured.\n\nPremise: {prompt}"}
]
input_ids = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)

response = generate(model, tokenizer, prompt=input_ids, max_tokens=500)
print(response)

🧠 Training Details

Base Model: mlx-community/gemma-2-9b-it-4bit
Dataset: shabul/devils-advocate-dataset (Synthetic dataset of controversial topics and counter-arguments).
Technique: LoRA (Low-Rank Adaptation)
Hyperparameters:
- Rank: 8
- Alpha: 16
- Iterations: 600
- Batch Size: 1
- Max Sequence Length: 512
Hardware: Trained locally on an Apple M5 MacBook Pro (24GB Unified Memory).

🧪 Example Case

User: Social media has done more harm than good for human connection.

Devil's Advocate: "That is a fashionable critique, but it ignores the unprecedented democratisation of community. Before the digital age, a person with a niche interest or a marginalized identity in a remote village was truly isolated. Today, that same person has access to a global tribe. The flaw in your logic is equating 'depth' with 'proximity'..."
