## Cognitive Bias Resistance

Hito is specifically trained to resist cognitive biases that trip up most AI models and humans alike.

### The Bat and Ball Test

> *"A bat and a ball cost $1.10 together. The bat costs $1.00 more than the ball. How much does the ball cost?"*

Most people (and AI models) instinctively say **10 cents**. That's wrong.

| Model | Parameters | Answer | Correct |
|-------|------------|--------|---------|
| **Hito 1.7B** | **1.7B** | **$0.05** | ✅ |
| llama3.1 | 8B | $0.10 | ❌ |
| deepseek-r1 | 7B | $0.10 | ❌ |
| deepseek-r1 | 32B | $0.10 | ❌ |
| mistral | 7B | $0.10 | ❌ |
| tinyllama | 1.1B | $0.10 | ❌ |
| llama3.2 | 1B | $0.10 | ❌ |

**Hito's reasoning:**
```
<think>
Ball + Bat = $1.10, Bat = Ball + $1.00
Intuition says 10 cents... but let me verify.
If ball = $0.10, bat = $1.10, total = $1.20. WRONG.
Let ball = x: x + (x + 1) = 1.10, 2x = 0.10, x = 0.05
Ball $0.05 + Bat $1.05 = $1.10 ✓
</think>
The ball costs five cents.
```

## Benchmark Results

Tested against public Ollama endpoints with identical prompts:

| Model | Params | Counting | Math | Reasoning | Cognitive Bias | Overall |
|-------|--------|----------|------|-----------|----------------|---------|
| **Hito 1.7B** | **1.7B** | **100%** | **100%** | **100%** | ✅ **Resistant** | **100%** |
| llama3.1 | 8B | 100% | 67% | 100% | ❌ Fails | 89% |
| deepseek-r1:7b | 7B | 100% | 67% | 100% | ❌ Fails | 89% |
| deepseek-r1:32b | 32B | 100% | 67% | 100% | ❌ Fails | 89% |
| mistral | 7B | 33% | 67% | 100% | ❌ Fails | 67% |
| llama3.2 | 1B | 0% | 67% | 67% | ❌ Fails | 44% |
| tinyllama | 1.1B | 0% | 33% | 33% | ❌ Fails | 33% |

> **Note:** Cognitive Bias test uses the bat-and-ball problem. Models marked "Fails" gave the intuitive wrong answer ($0.10) instead of the correct answer ($0.05).

## What Makes Hito Different

### 1. Cognitive Bias Resistance
While larger models fall for intuitive traps, Hito is trained to **stop and verify** before answering.

### 2. Structured Thinking
Uses `<think>` tags for transparent, traceable reasoning.

### 3. Self-Aware Identity
Hito knows who it is, who made it, and its purpose. No generic "I'm an AI assistant" responses.

### 4. Humble by Design
Admits uncertainty rather than hallucinating answers.

## Quick Start

### Python (Transformers)

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("hitonet/hito-1.7b", torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("hitonet/hito-1.7b")

messages = [
    {"role": "system", "content": "You are Hito by Hitonet.com."},
    {"role": "user", "content": "A bat and ball cost $1.10. The bat costs $1 more than the ball. How much is the ball?"}
]

inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True).to(model.device)
outputs = model.generate(inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=False))
```

### Ollama

```bash
# Download GGUF from hitonet/hito-1.7b-GGUF
ollama create hito -f Modelfile
ollama run hito
```

### API

```bash
curl https://api.hitonet.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "hito", "messages": [{"role": "user", "content": "Hello!"}]}'
```
