The success-rate of ChatGPT's outputs is an important quantity to consider for estimating the (optimization) power of ChatGPT. Defined as the likelihood a user responds to an output from ChatGPT instead of using "Try again", the success-rate retains information about the expected advantage that ChatGPT has over the user.
In lieu of a reward function, which may be learned mostly in-context, the success-rate seems like a reasonable proxy to evaluate ChatGPT. However, it may be hard to estimate relative power from just the success-rates when we are dealing with the extremes. Intuitively, the success-rate can be thought of as the likelihood a user prefers one of ChatGPT's responses to their own. A previous argument also establishes a way to upper-bound the relative power when given this likelihood which we show below.
This result requires an assumption that there is some distribution of MDPs that ChatGPT and the user can be modeled as interacting over. We treat the context that a user or ChatGPT responds to as the state. Either party takes action by generating responses into a console that is read out to both parties as an append to the context. The reward depends on the user and is assumed to have reasonable concentration properties.
One potential objection to the use of acceptance rates as a proxy for estimating the power of ChatGPT is that it may not always be a reliable or accurate measure. For example, some users may be more likely to respond positively to ChatGPT's outputs, even if they are not objectively better than their own responses. This could lead to inflated acceptance rates and a misleading estimation of ChatGPT's performance. Additionally, the acceptance rate may not always be reliable because it depends on the user's behavior, which may be influenced by factors such as their mood, motivation, or attention level. It may be necessary to provide more evidence or examples that show how acceptance rates can be used to reliably estimate the power of ChatGPT in a variety of contexts. For example, this could be done using data or results from experiments or simulations that demonstrate the correlation between acceptance rates and relative power.
There are three key takeaways from our observations. First, when success-rates are low, there may be a much larger spread of relative (optimization) power, which can make it difficult to form a consensus about the capabilities of the underlying model. However, this does not necessarily mean that the model is vastly inferior. Instead, it could simply mean that the user has different preferences or goals, or that the model's responses are not always relevant or useful in the given context.
Second, when success-rates are in-between, it becomes much easier to assess the capabilities of the underlying model. This is because the success-rate provides a more reliable and consistent measure of the model's performance, and allows us to compare the model's responses to the user's responses in a more objective and unbiased way.
Finally, when success-rates become high, it may again become difficult to form a consensus about the relative advantage of the model. This is because some people may conclude that the model is vastly superior, while others may continue to have doubts or reservations about the model's performance. However, even in this case, the high success-rate provides strong evidence that the model is capable of generating responses that are relevant and useful to the user, and that it can outperform the user in many scenarios.
In conclusion, the success-rate of ChatGPT's outputs is an important quantity to consider when estimating the (optimization) power of ChatGPT. By providing a measure of the likelihood that a user responds to an output from ChatGPT instead of using "Try again", the success-rate retains information about the expected advantage that ChatGPT has over the user. However, it is important to recognize the limitations and implications of this approach, and to consider alternative ways of estimating the relative power of ChatGPT.
