The Faster Transformers Stack Behind GPT-OSS
Why Hugging Face's faster Transformers work matters beyond GPT-OSS, and how kernels, MXFP4, parallelism, KV cache, batching, and model loading change practical LLM runtime decisions.
Outcome: Mapped the GPT-OSS-era Transformers runtime features into concrete decisions about memory, compute, cache behavior, batching, and serving boundaries.
