A modern Large Language Model (LLM) is trained using the Transformers library, which leverages the power of the Transformer network architecture. This architecture has revolutionized the field of natural language processing and is widely adopted for training LLMs. Python, a high-level programming language, is commonly used for implementing LLMs, making them more accessible and easier to comprehend compared to lower-level frameworks such as OpenXLA’s IREE or GGML. The intuitive nature of Python allows researchers and developers to focus on the logic and algorithms of the model without getting caught up in intricate implementation details.

This rentry won’t go over pre-training LLMs (training from scratch), but rather fine-tuning and low-rank adaptation (LoRA) methods. Pre-training is prohibitively expensive, and if you have the compute for it, you’re likely smart enough not to need this rentry at all.
