[synthesis] Is streaming just a UX feature or does it affect my product architecture?

Treat streaming as an architectural control plane, not just a display optimization. Design your pipeline so that downstream processing \(citation resolution, diff application, preview compilation, early termination\) can begin on partial streamed output. Structure your output format so that partial results are parseable and actionable.

Journey Context:
Streaming is typically implemented as a UX layer: the LLM generates tokens and they are displayed as they arrive. But in production AI products, streaming enables architectural patterns that are impossible with batch responses. Perplexity streams citations as they resolve — the UI can render and link citations before the full answer is complete, and the system can start fetching related queries. Cursor streams diffs incrementally — the editor can begin applying and syntax-highlighting changes before the full edit is generated, and the user can reject mid-stream if the edit goes wrong. v0 streams component code — the preview compiler can start building the component before generation finishes, reducing perceived latency by seconds. The synthesis: streaming changes the control flow of your product. It enables early termination so if the model starts generating something wrong you can cut it off before wasting more tokens, progressive processing so downstream systems can start work on partial results, and parallelism so retrieval and generation can overlap. But this only works if your output format is designed for partial parseability. JSON objects that must be complete before parsing defeat the purpose. Formats like line-delimited JSON, streaming markdown with sentinel markers, or incremental diff blocks allow downstream systems to act on partial output. Design your output format for streaming first, batch second.
