How this channel uses clearance In this channel's material, clearance refers to the go-ahead from a medical professional — the permission someone needs before resuming an activity during pregnancy or after a health event. It appears in the context of Sarah Rose Siskind's ChatGPT project for managing her health and pregnancy, where health and life-logistics questions (including when it is safe to do something) are the kind of decisions a model can help track, while the actual authorization comes from human medical judgment.
