π New blog: Maintain the unmaintainable β 1M+ Python LOC, 400+ models
How do you stop a million-line library built by thousands of contributors from collapsing under its own weight? At π€ Transformers, we do it with explicit software-engineering tenets, principles that make the codebase hackable at scale.
π Inside the post: β One Model, One File: readability first β you can still open a modeling file and see the full logic, top to bottom. β Modular Transformers: visible inheritance that cuts maintenance cost by ~15Γ while keeping models readable. β Config-Driven Performance: FlashAttention, tensor parallelism, and attention scheduling are config-level features, not rewrites.
Written with @lysandre,@pcuenq and @yonigozlan, this is a deep dive into how Transformers stays fast, open, and maintainable.
