That's a different part of the implementation details. If you were to break the system into mocroservices, the model is a binary blob with a mocroservices wrapper and accessing web search is another microservice entirely. You really don't want the entire web to be constantly compressed and re-released as a new model iteration, it's super inefficient.

Technically you’re correct, but from a product point of view one should be able to get answers beyond the cut-off date. The current product fails to realise that some queries like “who is the current president of the USA” are time based and may need a search rather than an excuse.
