Dynamic Speculation Lookahead

Faster Assisted Generation with Dynamic Speculation

Hugging Face introduces dynamic speculation lookahead for assisted (speculative) decoding, a technique that adaptively adjusts the number of candidate tokens generated by a draft model before verification by the main model. This approach aims to improve throughput and reduce latency compared to fixed-lookahead speculative decoding by tuning the speculation depth at runtime. The blog post describes the method and its integration into the Hugging Face Transformers library.
