custom benchmark

Optima — Custom AI Benchmark Builder (Artificial Analysis)

A platform from Artificial Analysis for building custom benchmarks from your own files, agent traces, or coding environment, then running them across leading models to compare quality, cost per task, and time per task. Benchmarks can be graded against objective rubrics or pairwise judging. Optima is a commercial product; the public announcement and product overview are free to read.

Why I recommend it: Standard benchmarks tell you which model is best in general; they cannot tell you which is best for your workload. If you are choosing a model for a real product, a custom benchmark on your own tasks is the right move — this is one way to do it without building the harness yourself.
