Baidu have a lot of services I've never heard of, that are highly successful in China. The lack of interest in expanding into Western audiences doesn't seem to matter there - what's different about inference?
Looking at Temu and Shien, there's a ton of interest in expanding into western audiences, the difference with inference is that they've found a way to make that happen. Vs, I don't have any use for, eg Baidu's equivalent to Google maps because I have, well, Google maps.
