Speculative decoding boosts on-device LLM speed by reducing memory reads

Speculative decoding is a technique designed to accelerate the text generation speed of large language models on resource-constrained devices. This method involves a smaller, faster draft model proposing multiple tokens ahead, which are then verified by the larger, primary model in a single pass. This approach is particularly effective on memory-bound hardware, such as the NVIDIA Jetson Orin Nano, as it significantly reduces the number of times model weights need to be read from memory, thereby increasing token generation speed without altering the output's statistical properties.

    Speculative Decoding: Faster On-Device LLMs

    <blockquote> <p>Speculative decoding makes a large language model generate text faster on a constrained device without changing what it produces. A small draft model guesses several tokens ahead, and the large model checks all of those guesses in a single pass. Because single-str…
