 Note: GPTQ and Marlin do not have bitwise correctness.
 As a result, in this test, we just confirm that the top selected tokens of the
 Marlin/GPTQ models are in the top 5 selections of each other.
 Note: Marlin internally uses locks to synchronize the threads. This can
 result in very slight nondeterminism for Marlin. As a result, we re-run the test
 up to 3 times to see if we pass.
