Decision brief
LLMs-from-scratch is a guide for building a ChatGPT-like language model using PyTorch, aimed at educational purposes and designed for use with accessible hardware.
Good fit when
- When you are interested in understanding the inner workings of large language models and want to build one from scratch using PyTorch.
- If you have limited access to specialized hardware and still want to experiment with building a language model, as the tool is designed to run on conventional laptops.
Avoid when
- If you are looking for a quick and efficient way to deploy a pre-trained language model without delving into the implementation details.
- When you require a production-ready solution, as LLMs-from-scratch is primarily designed for educational purposes and may not be optimized for industrial use.
- Requirements:
- Min 8 GB RAM; The code automatically utilizes GPUs if they are available, but it is designed to run on conventional laptops without specialized hardware.
