GPT-Live only gets 205 ms faster, but latency jitter drops by 80%

A benchmark report on GPT-Live’s latency says its main improvement is consistency, not raw speed.
- Median response time improves by only 205 ms compared with the previous advanced voice mode.
- But latency variance drops sharply: standard deviation falls from 489 ms to 104 ms.
- The report argues that this lower jitter is what makes the experience feel smoother and more predictable.
- It also shows interruption-stop latency and false-interruption behavior measured on an iPhone with controlled network conditions.
