Fine tuning classification in Elixir (opens in new tab)

Fine tuning classification in Elixir 8 Jun 2026 by karlosmid I fine-tuned a GPT-2 model for ham/spam SMS classification in Elixir. This post follows chapter 6 of Sebastian Raschka’s Build a Large Language Model From Scratch, but instead of Python/PyTorch, I implemented the training pipeline in Elixir with Nx. For me, the most interesting part is not only that GPT-2 can be fine-tuned for classification, but that Elixir is becoming a serious environment for machine learning experiments.
