If the belief that open-weight/Chinese models depend significantly on distillation of the latest frontier models is correct, then presumably the gap will stabilise to the minimum time required for extraction of meaningful data (from the latest frontier model) plus finalisation of training of the latest dependent model. This gap can be minimised by increasing the process efficiency, but can't be eliminated entirely. (Attempts to hinder distillation from Anthropic/OpenAI may shift the balance too.)
