I have a question about what "validation" means exactly. Does this process work by having the main model compute the "probability" that it would generate the draft sequence, then probabilistically accepting the draft? Wondering if there is a better method that preserves the distribution of the main model.
If the workload were perfectly parallelizable, your claim would be true. However, if it has serial dependency chains, it is absolutely worth it to compute it quickly and unreliably and verify in parallel
