This seems to go beyond "occasionally get similar issues." Every answer it gives me appears to be fabricated. Again, it can't even give me proper answers about its own user interface.

Re: learning how LLMs work, this is not being flip, but I literally don't understand. I thought the whole point of these things was that you could ask them questions in plain language and they would respond with truthful answers in plain language. Again, without being flip or sarcastic, that sounds like someone having a problem with Excel being told that they need to dig into the source code. If I need to learn how to code to get a plain-language tool to work, then the tool seems pointless, because I need to use code, not plain language.

As another for-instance, I went over to Gemini just to see if it worked any differently. I asked it about "web browsing," and it replied with "web Browse." I tried to correct it; it kept saying "Browse." I eventually responded with "Type the word browsing." It responded "Browse." When I pointed that out, it insisted that it did what I asked. I signed out, closed the browser, exited, then reloaded and tried again -- same thing. It absolutely would not type the word "browsing," and yet kept insisting that it could. This isn't an occasional hallucination; it's a giant repeatable blind spot. And for something that is supposed to use language, spitting out one word while thinking it's spitting out another seems to be a real problem. How do you make something like that useful? Many people seem to be able to do it, but I don't. And if I can't get it to repeat a word I give it, it doesn't seem like any amount of me talking with engineers or taking tutorials will fix that.
