Basically, multiple submodels are part of GPT-5, and there is a model router that decides, when you ask a query, if the query requires one, or another, of the models to answer the query, for better performance. If you are able to disable the model router, but it is available or on by default, this market resolves YES.

If sufficiently ambiguous / unknown, may resolve N/A, but mostly if there is no given indication of this, the market will resolve NO.
