📰 Medium · LLM

Learn to build a foundational layer for an LLM from scratch, starting with token embeddings, to understand the basics of LLM architecture and stability

intermediate Published 21 Jun 2026
Action Steps
  1. Build a token embedding layer using popular libraries like TensorFlow or PyTorch
  2. Configure the embedding layer to handle out-of-vocabulary tokens
  3. Test the embedding layer with a sample dataset to ensure structural stability
  4. Apply techniques like normalization and regularization to improve embedding quality
  5. Compare different embedding techniques, such as word2vec and GloVe, to determine the best approach for your LLM
Who Needs to Know This

NLP engineers and researchers can benefit from this knowledge to design and develop more efficient LLMs, while data scientists can apply this understanding to improve their LLM-based projects
