# Qwen2-1.5B Fine-tuned on Synthia v1.5-II

A special thanks to Redmond.ai for sponsoring the GPU resources for this fine-tuning process.

This model is a fine-tuned version of [Qwen/Qwen2-1.5B](https://huggingface.co/Qwen/Qwen2-1.5B) on the Synthia v1.5-II dataset, which contains over 20.7k instruction-following examples.

## Model Description

Qwen2-1.5B is part of the latest Qwen2 series of large language models. The base model brings significant improvements in:
- Language understanding and generation
- Structured data processing
- Support for multiple languages
- Long context handling

This fine-tuned version enhances the base model's instruction-following capabilities through training on the Synthia v1.5-II dataset.

### Model Architecture
- Type: Causal Language Model
- Parameters: 1.5B
- Training Framework: Transformers 4.45.0.dev0

## Intended Uses & Limitations

This model is intended for:
- Instruction following and task completion
- Text generation and completion
- Conversational AI applications

The model inherits the capabilities of the base Qwen2-1.5B model, while being specifically tuned for instruction following.
