Build and control your own LLMs

Build and control your own LLMs

xturing provides fast, efficient and simple fine-tuning of LLMs, such as LLaMA, GPT-J, GPT-2, OPT, Cerebras-GPT, Galactica, and more. By providing an easy-to-use interface for personalizing LLMs to your own data and application, xTuring makes it simple to build and control LLMs. The entire process can be done inside your computer or in your private cloud, ensuring data privacy and security.

With xturing you can,

• Ingest data from different sources and preprocess them to a format LLMs can understand
• Scale from single to multiple GPUs for faster fine-tuning
• Leverage memory-efficient techniques (i.e. LoRA fine-tuning) to reduce your hardware costs by up to 90% of the time
• Explore different fine-tuning methods and benchmark them to find the best performing model
• Evalate fine-tuned models on well-defined metrics for in-depth analysis

⚙️ Installation

pip install xturing

🚀 Quickstart

from xturing.datasets import InstructionDataset
from xturing.models import BaseModel

# Load the dataset
instruction_dataset = InstructionDataset("./alpaca_data")

# Initialize the model
model = BaseModel.create("llama_lora")

# Finetune the model
model.finetune(dataset=instruction_dataset)

# Perform inference
output = model.generate(texts=["Why LLM models are becoming so important?"])

print("Generated output by the model: {}".format(output))

📊 Performance

Here is a comparison for the performance of different fine-tuning techniques on the LLaMA 7B model. We use the Alpaca dataset for fine-tuning. The dataset contains 52K instructions.

Hardware:

4xA100 40GB GPU, 335GB CPU RAM

Fine-tuning parameters:

{
  'maximum sequence length': 512,
  'batch size': 1,
}

Please submit your performance results on other GPUs.

📈 Roadmap

• Support for LLaMA, GPT-J, GPT-2, OPT, Cerebras-GPT, Galactica and Bloom models
• Dataset generation using self-instruction
• 2x more memory-efficient fine-tuning vs LoRA and unsupervised fine-tuning
• INT8 low-precision fine-tuning support
• Evaluation of LLM models
• Support for Stable Diffusion
