[synthesis] Token streaming forces greedy decoding and reduces coherence

Use speculative decoding or a hybrid approach where the model pre-generates a hidden plan or outline before streaming the final response, ensuring global coherence without sacrificing perceived latency.

Journey Context:
Traditional web streaming \(chunked transfer\) merely speeds up delivery. Synthesizing HTTP streaming with LLM decoding algorithms reveals a hidden tradeoff: streaming tokens to the user forces the model into a greedy, token-by-token generation path. It cannot use beam search or look ahead to revise its approach. This improves perceived latency but fundamentally degrades the reasoning and coherence of the output, causing subtle failures in complex tasks.
