Unpredictable wait times : Wait times (latency) for ChatGPT’s responses are unpredictable, and there aren’t audio cues to help me establish an expectation for how long I need to wait before it responds. Thank you very much for reading. Sooo, what do YOU think about ChatGPT’s voice mode?!? What’s YOUR favorite and least favorite parts?

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

One of the slides I omitted to shorten this version of the talk highlighted that there are actually two issues when you go from “Disjoint (tightly coupled)” to “Disjoint (loosely coupled)”: reliability and latency , and both are important. (I I also mentioned this in the original WttJ article this is based on; just search for “reliability.”).
