📰 Medium · LLM

Learn to fine-tune a large language model (LLM) to follow instructions effectively, covering tokenization, padding, and batching techniques

intermediate Published 12 Apr 2026
Action Steps
  1. Apply tokenization to input text using libraries like Hugging Face's Tokenizers
  2. Configure padding to handle variable-length input sequences
  3. Implement the -100 trick to ignore padded tokens during training
  4. Test batching techniques to optimize training efficiency
