It seems like the Mistral models (Large and Pixtral) do not make use of the web access (which might also be possibly be linked to the "Sorry, a problem occurred while processing your request. Please try again later.").

While other models have Access (and no errors).

It seems that the internet is only accessed via other apps/searchengines (like in this case Wolfram Alpha) and when shortly the status "Searching with Kagi" is visible, but this cannot be triggered reliable.

That the models access the internet to get up-to-date information, which influences the output.
