Data quality

Most of what Poseidon shows is read straight from Meta. A few labels are written by AI. Here is how often each one is right, measured on ads people checked by hand, and what we hold back until it is good enough.

Read straight from Meta, never written by AI

Every number shows the day it was read.

Labels written by AI, and how often they're right

Each label is checked against ads a person labelled by hand, ads the AI had never seen. The dot is how often the AI was right; the line is the likely range. A label is served only when it is right at least 90% of the time and the low end of its likely range is 85% or more.

Hook type
