Speculative decoding’s potential to speed up AI text extraction
A post argues that vision-language models can spend a lot of time writing Markdown when extracting document text, making output generation a target for speedups.
TLDR
A post describes speculative decoding as a way to reduce delays when vision-language models perform optical character recognition (OCR). A fast draft model proposes several tokens, which the main model checks together. Accepted tokens advance the output; rejected proposals get corrected. The author says this reduces time spent on sequential decoding steps, especially when a document’s structure makes text easier to predict.
