I am simplifying the behavior of these systems, but my argument is twofold. First,, just because an output has a high probability of being correct, doesn't mean that any particular output is correct. Second, "low probability" events that are acceptable in a limited use case are disastrous in broader use.
For example, If I were being generous, I'd say that GPT-4 makes an error 0.1% of the time i.e. 99.9% of the time it doesn't make an error. I would say that is extremely fair. I use this model daily and I've found the rate in my limited sample set to be higher than that.
If you are dealing with 10 cases, a 0.1% error rate is immaterial. If you are dealing with 100,000 cases, that's 100 cases where an error was introduced.
The true error rate is likely to be higher, for example, https://www.ncbi.nlm.nih.gov/corecgi/tileshop/tileshop.fcgi?...
Is it acceptable for a few thousand to a few hundred innocent people to face legal action because an overgrown next token prediction model made a mistake?
I love GPT-4. I love its promise, but I don't think it should be implemented in safety-critical situations.
