# Tiny Add2 LLM 10MB

This is a **tiny addition-only model package**. It is not a real general-purpose LLM like Llama/GPT. It is made for one job only:

> add exactly 2 non-negative numbers.

Example:

```bash
python infer.py "12 + 30"
# 42
```

## What is included

- `model/add2_model.bin` — 10 MB model file
- `model.py` — model loader
- `infer.py` — one-shot addition answer
- `chat.py` — simple chat mode
- `build_model.py` — rebuild the 10 MB model file
- `test_model.py` — quick tests

## Limit

Default model supports numbers from `0` to `2199`.

Valid inputs:

```text
12 + 30
add 15 and 7
100 plus 55
```

Invalid inputs:

```text
hello
12 + 30 + 5
-1 + 5
99999 + 1
```

## Run on PC

```bash
pip install -r requirements.txt
python infer.py "123 + 456"
python chat.py
```

## Rebuild model

```bash
python build_model.py --max-number 2199 --target-mb 10 --out model/add2_model.bin
```

## Hinglish note

Bhai, ye ek chhota **addition-only mini model** hai. Ye chatbot jaisa general answer nahi dega. Sirf 2 number add karega.
