New technique compresses token space to speed up LLM constrained decoding

Researchers have developed CFGzip, a novel offline technique designed to significantly speed up constrained decoding in large language models (LLMs). This method compresses the token search space, drastically reducing the overhead associated with ensuring LLM outputs conform to specified context-free grammars (CFGs). Experiments show that CFGzip can reduce latency by up to two orders of magnitude, leading to a 7.5x speedup in total constrained generation time, making complex CFG decoding feasible at scale. AI
