Models are told the user is in the USA when using the web tool

That’s surprising!

You’re saying the intended behaviour is that if I don’t know where my users are, and so don’t provide location details with the web search tool, that OpenAI will assume that my users are in the USA?

I’d say that’s quite a bad assumption to make.

Your response focused on the case where I do know my user’s location, or can approximate it. I understand that if that were the case, then I should provide that info.

But that’s not the scenario I’m describing. I’m talking about the case where I DO NOT know where my users are, and that OpenAI make the assumption that this means my users are in the USA.
