# Zurich 1.5B GammaCorpus v2-10k 
*A Qwen 2.5 model fine-tuned on the GammaCorpus dataset*

## Overview
Zurich 1.5B GammaCorpus v2-10k is a fine-tune of Alibaba's **Qwen 2.5 1.5B Instruct** model. Zurich is designed to outperform other models that have a similar size while also showcasing [GammaCorpus v2-10k](https://huggingface.co/datasets/rubenroy/GammaCorpus-v2-10k).

## Model Details
- **Base Model:** [Qwen/Qwen2.5-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-1.5B-Instruct)
- **Type:** Causal Language Models
- **Architecture:** Transformers with RoPE, SwiGLU, RMSNorm, and Attention QKV bias
- **Number of Parameters:** 1.54B
- **Number of Paramaters (Non-Embedding)**: 1.31B
- **Number of Layers:** 28
- **Number of Attention Heads (GQA):** 12 for Q and 2 for KV


## Training Details

Zurich-1.5B-GCv2-10k underwent fine-tuning with 1 A100 GPU for ~5 minutes and trained with the [Unsloth](https://unsloth.ai/) framework. Zurich-1.5B-GCv2-10k was trained for **60 Epochs**. 

## Usage

### Requirements

We **strongly** recommend you use the latest version of the `transformers` package. You may install it via `pip` as follows:

```
pip install transformers
```

### Quickstart

Here is a code snippet with `apply_chat_template` to show you how to load the tokenizer and model and how to generate contents;

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "rubenroy/Zurich-1.5B-GCv2-10k"

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

prompt = "How tall is the Eiffel tower?"
messages = [
    {"role": "system", "content": "You are Zurich, an AI assistant built on the Qwen 2.5 1.5B model developed by Alibaba Cloud, and fine-tuned by Ruben Roy. You are a helpful assistant."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
```
