Diff between retrieved documents

[Muennighoff]

Cool idea from @KarelDO

A feature to produce a GPT-generated diff of the retrieved documents rather to save voters time.
Though this adds some additional bias. Rather than that, maybe we should just start looking into adding some GPT/Claude votes soon, check if they correlate with human votes, and if so use them to supercharge the leaderboard with more votes. In case someone has bandwidth, lmk!!
