How to Test New AI Models Like a Pro: Create Your Own Benchmarks for Smarter Decisions

“A new AI thing has appeared!”

This sort of announcement is an almost daily occurrence in the world of AI and a major contributor to people feeling overwhelmed and exhausted.

Here’s one way to deal with that: have your own tests.

This is something I deal with a lot in the use of open models (ones you download). There are, as of this morning, 1,803,158 open models in generative AI, with about a thousand new AI models appearing every day.

When I say have your own tests, I mean have a benchmark set of prompts that test models to see how they perform on your specific tasks. Have a deep, complex set of prompts that test:

  • Obeying instructions, especially multistep instructions
  • Reasoning and thinking
  • Creativity and fluency in writing
  • Writing code or fancy outputs

Then when a new model drops, you run your tests, compare it to other models, and decide whether the new model is an improvement or not for things specific to you.

The big benchmarks that everyone uses – GPQA, MMLU, and the rest of the alphabet soup that makes up AI model testing is useful as a general apples-to-apples comparison of different models, but they are not specific to you. They don’t test what you test. They don’t care about what you specifically care about.

Here’s an example of a test. Take a beefy piece of your own content, 100% written by you, that has never been made public. Then you write a detailed prompt about how to reconstruct that piece – tone of voice, general outline of the piece, key points the AI must hit. Think of the instructions you’d give a ghostwriter, and write that all out.

Then feed that prompt into any new AI tool that comes along and see how close the new thing gets to your original. You may find that a new AI thing that doesn’t get much hype turns out to really nail the task. You may find that the biggest hyped thing performs badly on the task.

Either way, you will QUICKLY have an answer as to whether you should care about the new thing or not in a concrete way that assuages your FOMO and satisfies your stakeholders that are easily distracted by shiny objects.
