How does a rigid silicon probe differ from Neuralink's flexible threads?

In what each optimises. A rigid shank such as Neuropixels goes in by itself and carries dense electronics, so it records many neurons in one column, mostly in animals and for hours to months. The N1 spreads 1,024 electrodes over 64 flexible polymer threads that a robot inserts one by one; they follow the brain's movements and scar less, which matters for years in a person, but the electronics have to live in a separate sealed package.
