Could you please clarify the revisit part? In case this will be assigned to another engineer, what are steps needed for this revision

Yes, there are two things to check:

  1. What is the goal of this test?
  2. Why request_params_n_sum assert failed? Is it expected with the vLLM 0.6.3.post1 update?

Basically, if we are updating/deleting request_params_n_sum assert, we need to know why it is safe to update.
