What is Tokenization?

Computers don't read text. They read numbers. Tokenization is the process that bridges the two. A sentence like "I am eating paratha" gets split into tokens, each assigned an ID, and then converted into embeddings the model can actually work with. GPT uses Byte Pair Encoding, which means words like "eating" can split into "eat" and "ing" as separate tokens. This is step one of how large language models are trained. #LargeLanguageModels #Tokenization #MachineLearning #AIEngineering #NLP #short
