# Amber Fable 1.0

## Model Description
**Amber Fable 1.0** is a **1.7B parameter** specialized language model, fine-tuned using **LoRA (Low-Rank Adaptation)** on the powerful **Qwen3-1.7B** base model. 

This model is engineered specifically for **mathematical reasoning** and **algorithmic logic**. It achieves remarkable performance on math benchmarks (75% on GSM8K) for its size class, making it a highly efficient solution for educational tools and logic-based tasks, although it trades off some general world knowledge (MMLU) to achieve this peak reasoning capability.

- **Developed by:** Arioron
- **Model type:** Decoder-only Transformer (LoRA Adapter)
- **Language(s):** English
- **License:** Apache 2.0
- **Finetuned from model:** Qwen/Qwen3-1.7B

## Quick Start

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_name = "Arioron/Amber-Fable-1.0"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Math reasoning example
messages = [
    {"role": "user", "content": "Natalia sold clips to 48 of her friends in April, and then she sold half as many clips in May. How many clips did Natalia sell altogether in April and May?"},
]

input_text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.6,
    do_sample=True,
    top_p=0.9,
    pad_token_id=tokenizer.eos_token_id
)

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