Are There Any Good Benchmarks Comparing OpenAI API Models?

I’m looking for benchmark results that compare OpenAI models specifically on mathematical reasoning. Most of the discussions I find are focused on coding or general reasoning, but I’m interested in seeing how the current models perform on benchmarks such as AIME, FrontierMath, or other math-focused evaluations. Does anyone have links to benchmark comparisons or personal experience using OpenAI models for math-heavy workloads?
