How to use this tool

  1. Enter stored vectors, dimensions, queries in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "vectors": 1000000,
  "dim": 768,
  "queries": 100
}

Accuracy and scope

One multiply per dimension plus reduction additions; normalization, top-k selection and approximate indexes excluded.
