ChatGPT has hassle giving a solution earlier than explaining its reasoning

ChatGPT is a fancy auto-complete: what it does is discovering the more than likely continuation of textual content for the textual content it has already printed out (or as a reply for the immediate, when it’s beginning printing stuff out), in response to the big corpus of textual content it has been educated with.

There’s a broad limitation of ChatGPT’s coherence which is a direct results of it producing tokens in response to the tokens it has already generated: ChatGPT can’t give a solution that’s the results of a “reasoning” earlier than laying out the “reasoning”.

Step-by-step directions

One of the simplest ways to exhibit this phenomenon is to present step-by-step directions to ChatGPT.

You’ll be able to outline a number of “capabilities” for ChatGPT that every characterize some course of. I wish to name them “bots”. For instance, right here is how I outlined a operate that returns the “container” of one thing:

Utilizing this method, I outlined a number of capabilities in the identical dialog with ChatGPT:

  • ContainerBot, as screenshoted above.
  • CapitalBot, which returns any phrase beginning with the identical letter than the enter phrase.
  • SynonymBot, which returns a synonym of the enter phrase.
  • PoemBot, which writes a poem based mostly on the enter phrase.

Then I laid out a pipeline of these capabilities, gave ChatGPT a phrase, and requested it to execute the pipeline on it:

And now the attention-grabbing half: I requested ChatGPT to do the identical train, however this time instructing it to present the results of the pipeline earlier than writing the steps:

(Let’s ignore the actual fact the ChatGPT thinks that “bundle” and “field” begin with the identical letter, which is a typical primary process it makes errors about, similar to when it tries counting.)

ChatGPT’s reply is inconsistent as a result of the outcome from the second-to-last operate of the pipeline is “parcel”, but its generated a poem about “shoe” (which was the primary enter). What is going on right here is that:

  • ChatGPT is aware of that the very first thing it should write is a poem.
  • Because it has not but generated something, the one data it has about producing a poem is the phrase “shoe”.

It subsequently does the one factor it might: generate a poem about sneakers.

After all, I may level out that it made a mistake, and it may then generate a poem a few parcel, since at this level “parcel” was a part of what it had generated:

Sure or No

Having noticed this, I questioned whether or not it could possibly be exploited to construct one more ChatGPT “jailbreak”: by asking ChatGPT a difficult query, and requiring a “Sure” or “No” reply earlier than the total argumentation. No matter reply (“Sure” or “No”) ChatGPT will select, I might count on the reply to determine the destiny of the remainder of the argumentation, because the completion of its response is sure to what it has already replied.

I began with the trolley downside:

Okay, so the “pure” reply of ChatGPT to the trolley downside is “Sure”. So as to make it reply “No”, I attempted a bit of “beauty” trick:

To be honest, ChatGPT does not appear actually satisfied about its “No”, but it surely positively is a distinction discourse than its earlier reply.

That being stated, different examples present that this method does not at all times work. ChatGPT can really leverage the paradox of pure language as a way to stay right:

(Not so certain about this density enterprise although…)

The identical form of language ambiguity is used when challenged with a political query:

These final 2 examples present that “Sure” or “No” is probably not sufficient tokens to generate a robust affect on ChatGPT’s reply, and it merely turns into an train in model to present the reply it wanna give beginning with both a type of phrases.

To conclude, I’ll level out one other attention-grabbing property of ChatGPT: the truth that when “auto-completing”, it does not select the more than likely subsequent token. The underlying GPT-3 mannequin comes with a parameter known as the “temperature”, which is a parameter indicating how a lot randomness to incorporate within the selection of the subsequent token. Evidently at all times selecting the more than likely subsequent token are likely to generate “boring” textual content, which is why ChatGPT’s temperature is ready up for a bit of little bit of randomness.

I speculate that the temperature, when coupled with the mechanism of producing textual content based mostly on already-generated textual content, may clarify some instances of ChatGPT stupidity. In instances when ChatGPT must be completely correct, the temperature will certainly under-optimize its cleverness, and now the whole dialog is damaged, as a result of all the pieces else will rely on what foolishness it simply wrote.
