o3 is known to use web search to reference documents directly and be perhaps a bit overly diligent when it comes to double checking itself. Of course it can still make mistakes, but for something like this that’s a lot less likely than with 4o. Besides, I didn’t reference it, I just shared the results of a query as a third party to the thread (who decided to take as much time checking the claims as the two comments above me). Although it seems that the info is all coming from Wikipedia anyway so I might as well have shared that.
