# 🧠 MiniCrit-1.5B  
**Adversarial Financial Critic LLM for Trading-Rationale Evaluation**

MiniCrit-1.5B is an adversarial financial-critic LLM trained to evaluate, stress-test, and rebut trading rationales produced by other LLMs.  
It serves as a **validator layer** for autonomous or semi-autonomous trading systems where hallucinated logic or weak reasoning may create financial risk.

The model **does not** generate trades.  
It **only** critiques reasoning quality.

## 📦 Model Description

**Base Model:** 1.5B-parameter transformer  
**Tuning Method:** ATAC-LoRA  
**Training Data:**  
- **MiniCrit-Training-12k** (12,132 rationale → critique pairs)  
- **FinRebut-600** curated evaluation set  

**Primary Abilities**
- Detect flawed or risky trading logic  
- Identify hallucinated financial statistics  
- Flag improper use of indicators  
- Provide adversarial rebuttals  
- Validate rationales before execution

## 📚 Datasets

### **1. MiniCrit-Training-12k**  
Large-scale dataset of institutional rationale/critique pairs.  
➡ https://huggingface.co/datasets/wmaousley/minicrit-training-12k

### **2. FinRebut-600**  
Curated, high-quality adversarial rebuttal set.

## 🚀 Intended Use

### ✔ Recommended:
- Validating LLM-generated trading rationales  
- Hallucination detection in financial explanations  
- Model-to-model critique pipelines  
- AI-safety analysis for financial agents  
- Research in adversarial financial reasoning  

### ❌ Not Recommended:
- Generating trades  
- Investment decision-making  
- Fully autonomous trading without human review  

This model is for **research** and **evaluation** only.

## 📈 Performance

### Forward-Test (Paper Trading)
| Metric | Value |
|--------|-------|
| Sharpe (baseline) | +0.20 |
| Sharpe (MiniCrit-validated) | **+0.80** |
| Hallucination reduction | **–48%** |
| Weak-reasoning detection F1 | **0.82** |
| Hallucination F1 | **0.76** |

### Qualitative Strengths
- Detects regime mismatch  
- Identifies liquidity illusions  
- Flags circular or self-justifying logic  
- Highlights data-mining  
- Generates strong evidence-demanding rebuttals

## 🔧 Usage

> This example works after the full model is uploaded to this repository.

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "wmaousley/MiniCrit-1.5B"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

prompt = """Rationale:
'NVDA is oversold so I will long because RSI is below 30.'

Provide a critique.
"""

inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(
    **inputs,
    max_new_tokens=200,
    do_sample=False,
    temperature=0.0,
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## 🛡️ Safety & Limitations

### Model Risks
- May produce overly forceful critiques  
- Sensitive to prompt phrasing  
- Limited deep macroeconomic understanding  
- Not a trading or financial-advice model  

### Mitigations
- Does not produce trade signals  
- Outputs critique only  
- Warns about high-risk reasoning patterns  
- Datasets avoid target-label leakage
