Tech experts are starting to doubt that ChatGPT and A.I. ‘hallucinations’ will ever go away: ‘This isn’t fixable’::Experts are starting to doubt it, and even OpenAI CEO Sam Altman is a bit stumped.

    I was excited for the recent advancements in AI, but seems the area has hit another wall. Seems it is best to be used for automating very simple tasks, or at best used as a guiding tool for professionals (ie, medicine, SWE, …)

      Hallucinations is common for humans as well. It’s just people who believe they know stuff they really don’t know.

      We have alternative safeguards in place. It’s true however that current llm generation has its limitations

        Not just common. If you look at kids, hallucinations come first in their development.

        Later, they learn to filter what is real and what is not real. And as adults, we have weird thoughts that we suppress so quickly that we hardly remember them.

        And for those with less developed filters, they have more difficulty to distinguish fact from fiction.

        Generative AI is good at generating. What needs to be improved is the filtering aspect of AI.

          Hell, just look at various public personalities - especially those with extreme views. Most of what some of them say they have “hallucinated”. Far more so than what GPT chat is doing.

        Sure, but these things exists as fancy story tellers. They understand language patterns well enough to write convincing language, but they don’t understand what they’re saying at all.

        The metaphorical human equivalent would be having someone write a song in a foreign language they barely understand. You can get something that sure sounds convincing, sounds good even, but to someone who actually speaks Spanish it’s nonsense.

          GPT can write and edit code that works. It simply can’t be true that it’s solely doing language patterns with no semantic understanding.

          To fix your analogy: the Spanish speaker will happily sing along. They may notice the occasional odd turn of phrase, but the song as a whole is perfectly understandable.

            Because it can look up code for this specific problem in its enormous training data? It doesnt need to understand the concepts behind it as long as the problem is specific enough to have been solved already.

              If that were true, it shouldn’t hallucinate about anything that was in its training data. LLMs don’t work that way. There was a recent post with a nice simple description of how they work, but I’m not finding it. If you’re interested, there’s plenty of videos and articles describing how they work.

              I can tell GPT to do a specific thing in a given context and it will do so intelligently. I can then provide additional context that implicitly changes the requirements and GPT will pick up on that and make the specific changes needed.

              It can do this even if I’m trying to solve a novel problem.

              It doesn’t have the ability to just look up anything from its training data, that stuff is encoded in its parameters. Still, the input has to be encoded in a way that causes the correct “chain reaction” of excited/not excited neurons.

              Beyond that, it’s not just a carbon copy from what was in the training either because you can tell it what variable names to use, which order to do things in, change some details, etc. If it was simply a lookup that wouldn’t be possible. The training made it able to generalize what it learned to some extent.

                Yes, but it doesnt do so because it understands what a variable is, it does so because it has statistics as to where variables belong most likely.

                In a way it is like the guy that won the french scrabble championship without speaking a single word of french, by learning the words in the dictionary.

            Sure it can, “print hello world in C++”

            #include 
            
            int main() {
              std::cout << "hello world\n";
              return 0;
            }
            

            “print d ft just rd go t in C++”

            #include 
            
            int main() {
              std::cout << "d ft just rd go t\n";
              return 0;
            }
            

            The latter is a “novel program” it’s never seen before, but it’s possible because it’s seen a pattern of “print X” and the X goes over here. That doesn’t mean it understands what it just did, it’s just got millions (?) of patterns it’s been trained on.

          Calculators don’t understand maths, but they are good at it.

          LLMs speak many languages correctly, they don’t know the referents, the don’t understand concepts, but they know how to correctly associate them.

          What they write can be wrong sometimes, but it absolutely makes sense most of the time.

            I’d contest that, that shouldn’t be taken for granted. I’ve tried several questions in these things, and rarely do I find an answer entirely satisfactory (though it normally sounds convincing/is grammatically correct).

      Yeah I fully expect to see genre specific LLMs that have a subscription fee attatched squarely aimed at hobbies and industries.

      When I finally find my new project car I would absolutely pay for a subscription to an LLM that has read every service manual and can explain to me in plain english what precise steps the job involves and can also answer followup questions.
