Classification by Fine-Tuning Methods

📝 Conversational

Fine-tuning for natural conversations with users involves training models to engage in human-like dialogue with appropriate context understanding and response generation.

🦙 Alpaca Format

The standard format from Stanford Alpaca project provides structured instruction-input-output formatting that has become widely adopted in the fine-tuning community.

🎯 GRPO (Group Relative Policy Optimization)

Advanced optimization technique based on reinforcement learning that significantly improves model response quality through sophisticated reward modeling and policy optimization.

👁️ Vision

Multimodal fine-tuning that processes text and images together, enabling models to understand and respond to visual content alongside textual information.

Practical Usage Methods

Getting Started with Google Colab

The process involves several straightforward steps:

Notebook Selection: Choose notebooks matching your desired model and use case Open in Colab: Click the “Open in Colab” button Runtime Setup: Select GPU runtime (T4 or higher specification) Step-by-Step Execution: Run notebook cells in order

Running on Kaggle

Kaggle environment offers the same notebooks with additional advantages:

Longer Execution Time: 30 hours of free GPU usage per week More Storage Space: 20GB output data storage capability Team Collaboration: Share notebooks and collaborate with team members

Advanced Use Cases

🧠 Reasoning Enhancement

Chain of Thought (CoT) fine-tuning for CodeForces problem solving demonstrates advanced reasoning capabilities through structured problem-solving approaches.

🛠️ Tool Calling

Training models to call external APIs or functions enables integration with external systems and services, expanding model capabilities beyond text generation.

🎨 Unsloth Studio

No-code/low-code environment for intuitive model fine-tuning provides accessible interfaces for users without extensive programming backgrounds.

Performance Optimization Tips

Memory Efficiency

Unsloth employs memory-saving optimization techniques including:

LoRA (Low-Rank Adaptation): Trains only subset of parameters instead of full model Gradient Checkpointing: Saves memory usage during training Mixed Precision Training: Improves training speed and efficiency

Dataset Preparation

Effective dataset preparation for successful fine-tuning involves creating high-quality datasets with clear instructions, relevant context information, and accurate, useful responses.
