# Supervised Fine-Tuned Qwen2.5-0.5B-Instruct (SFT)
|
||||
|
||||
This repository contains a **Supervised Fine-Tuned (SFT)** version of **Qwen2.5-0.5B-Instruct**. The model has been fine-tuned on a custom instruction-following conversational dataset to answer questions about Vishnu in a natural and helpful manner.
|
||||
|
||||
## Model Details
|
||||
|
||||
* **Base Model:** `Qwen/Qwen2.5-0.5B-Instruct`
|
||||
* **Training Method:** Supervised Fine-Tuning (SFT)
|
||||
* **Framework:** Hugging Face Transformers
|
||||
* **Task:** Conversational Text Generation

# Training Overview
|
||||
|
||||
This model was fine-tuned using **Supervised Fine-Tuning (SFT)** on a custom instruction-response dataset.
|
||||
|
||||
The training process included:
|
||||
|
||||
* Instruction-response formatting using the Qwen chat template
|
||||
* Hugging Face Transformers
|
||||
* TRL SFTTrainer
|
||||
* PyTorch
|
||||
* Custom conversational dataset
