Transformers Modernizes Library With v5 Release

Hugging Face has released Transformers v5, a major library update that modernizes model APIs, unifies multimodal processors, and removes legacy interfaces. The release, highlighted in the Hugging Face blog, claims up to 20–30% faster inference and lower memory overhead across workloads, and supports more than 300,000 pretrained models as of 2025. Developers should expect minor refactoring but improved production stability and composability.
