~Don't~ Repeat Yourself: Hugging Face Transformers Design Philosophy

This Hugging Face blog post articulates the design philosophy behind the Transformers library, explaining why it deliberately violates the DRY (Don't Repeat Yourself) software engineering principle. The library favors explicit, self-contained model implementations over shared abstractions, prioritizing readability and ease of contribution over code reuse. This design choice reflects a deliberate tradeoff suited to the fast-moving ML research ecosystem where model architectures change rapidly.
