Introduction A First Look at the MI455 MI455 on Transformers What comes next
Introduction
At Advancing AI 2026, AMD introduced the AMD Instinct MI455X, its newest datacenter GPU for AI. The headline specification is hard to miss: 432 GB of high-bandwidth memory on a single GPU.
For Hugging Face, the MI455 marks the next step in our close collaboration with AMD, guided by a simple goal: make the Hugging Face ecosystem work across AMD hardware and take full advantage of each platform. Transformers already runs daily CI on MI300 infrastructure, and this year we’re expanding coverage to Ryzen and Radeon systems. At the kernel level, we’re also working with the AITER team to bring optimized AMD kernels to the Hugging Face Hub, where they can be used directly in Transformers workflows.
