Llm

Two stacked flowcharts showing the LLM generation pipeline (prompt to tokenize to model to sample to next token, with a stochastic loop) and the embedding similarity pipeline (word to lookup to vector to cosine to similarity score)

LLM & Embeddings — One Predicts Words. One Maps Meaning.

A walk through the two foundational mechanisms behind every modern NLP system — generative language models and similarity-based embeddings — using five hands-on exercises with Hugging Face and Gensim. Week 6 mini-project of the IITM Pravartak Professional Certificate Programme in Agentic AI.
