LLMs-from-scratch alternatives

rasbt/LLMs-from-scratch (108k stars, +630 this week): Implement a ChatGPT-like LLM in PyTorch from scratch, step by step.

Below are 12 other LLM tooling repos tracked by OSS Radar that share at least two GitHub topics with LLMs-from-scratch, ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
