UnverifiedResearch generally shows that waits exceeding one second significantly interrupt users' flow of operation.77% similarUnverifiedThe ±10% jitter causes all clients that failed at 0 seconds to wait 450-550 milliseconds, so that 80 retries arrive crowded into the same 100-millisecond window, forming waves and failing to effectively spread out retry timing.76% similarUnverifiedSome vendors have compressed perceived latency to within 500 milliseconds through streaming processing, but it remains difficult to consistently meet this target in complex query scenarios.75% similarVerifiedThe industry-recognized threshold for natural conversation is an end-to-end latency of 500 milliseconds or less; beyond this threshold, users will noticeably perceive a pause.74% similarUnverifiedStreaming output can reduce the user-perceived time-to-first-token from several seconds down to the millisecond level.74% similar
