): Typically between 32,000 and 128,000 tokens. A larger vocabulary reduces sequence length but increases the embedding layer's memory footprint.

The development of large language models (LLMs) has revolutionized the field of natural language processing (NLP). These models have achieved state-of-the-art results in various applications, including language translation, text generation, and question answering. However, building an LLM from scratch requires significant expertise, computational resources, and data. In this review, we provide a comprehensive overview of building an LLM from scratch, covering the key components, challenges, and best practices.
