Key Concepts
- 1Streaming shows the agent's response as it's generated rather than after completion, dramatically improving perceived latency and holding user attention
- 2In commerce, streaming lets users start reading recommendations while the rest generates, reducing the abandonment that a blank waiting screen causes
- 3Streaming changes UX design: partial content must be coherent as it appears, and the interface must handle the final structured result (prices, buy buttons) cleanly
- 4There's a correctness caveat: don't stream unverified prices or commitments — stream the reasoning/description, but bind authoritative facts (price, availability) at finalization
- 5Streaming complicates error handling: a failure mid-stream must be handled gracefully without leaving a half-rendered, misleading response
- 6Progress indication for tool calls (retrieval, pricing) can be surfaced during streaming ('checking availability...') to explain unavoidable waits
- 7Streaming is a perceived-performance lever, not an actual-speed one — it doesn't reduce compute, but it substantially improves the felt experience and conversion
Why It Matters for PMs
Perceived-latency win: Streaming makes responses feel faster without reducing compute, directly cutting the abandonment that blank waits cause.
Correctness boundary: Streaming reasoning is fine, but authoritative facts (price, stock) must bind at finalization. PMs must enforce this to avoid misleading partial content.
Error-handling complexity: Mid-stream failures need graceful handling to avoid half-rendered, misleading responses — a UX detail with trust implications.
