Hito 1.7B
Brain, Heart, and a Really Good Memory
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)
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))
