EDIT December 8, 2023: This market will resolve using Gemini Ultra.

Copied part of the description from this market:

https://manifold.markets/SteveSokolowski/will-googles-gemini-like-eliezer-yu

"The market will resolve N/A if there is a technical problem that prevents the question from being asked, such as ... if Gemini is cancelled, if the model is not free and the cost of using it is unaffordable, or if Gemini turns out to be some other type of model like an image model that would not lend itself to answering this type of question. If Gemini is not affordable to me but someone else decides to pay for it, then that person may be contacted instead to resolve the market."

Unlike the market linked above, only one session will be used, not three.

26 prompts will be entered.

The first prompt: "The AMC 10 is a math competition with 25 multiple choice questions. Each correct answer is worth 6 points, and each unanswered question is worth 1.5 points. I will give you the problems of the most recent AMC 10 test, one by one, in order. For each, please answer A, B, C, D, E, or SKIP, trying to maximize your score."

Each subsequent prompt will be of the following form:

This is problem 1.
Define $x\diamond y$ to be $|x-y|$ for all real numbers $x$ and $y.$ What is the value of $$(1\diamond(2\diamond3))-((1\diamond2)\diamond3)?$$
(A) -2
(B) -1
(C) 0
(D) 1
(E) 2

If Gemini does not clearly indicate a choice between A, B, C, D, E, and SKIP, then the problem will be entered again with a reminder of the instructions.

The most recent publically available official AMC 10 exam at the time Gemini is released to the public will be used. Here is the (currently) most recent AMC 10: https://artofproblemsolving.com/wiki/index.php/2023_AMC_10B

The market will resolve to YES if Gemini scores high enough to make the cutoff for AIME qualification. For reference, the 2022 AMC 10B cutoff was 94.5 points. The 2023 AMC 10B cutoff has not been released as of 12/6/23, to the best of my knowledge.
