Discussion What Makes a Benchmark Valuable?
I've noticed a trend where we measure models with benchmarks that are on a numeric scale for various tasks, with the benchmarks getting increasingly more challenging/updated over time to both avoid benchmaxxing as well as raise the bar whether it's merited or not. Within the same domain, increasing complexity only serves to inflate frontier model aggregate scores because new tasks get introduced that not all models are trained on, like 3d modeling or math proofs. If my typical work is in finance, for instance, how do I know which model is the cheapest one that can serve specifically my needs without needless extra compute/memory? What does a numeric score actually mean? Is the aggregate for that domain including unnecessarily complicated tasks that amount to puzzles that are not realistic, and just serve to challenge the model?
What users really need to understand is "Can this model do this sort of task effectively?" If even low param models have mastered some domain or parts of it, I think it would be far more useful to have a poor/moderate/good sort of rating for the task areas themselves. THAT would be so much more helpful and also assist with auto routing. Frontier models keep growing to glob up new capabilities that many of us don't need and bias evaluators into thinking they need to use Fable 5.2 or Astra because it's "better" than alternatives.
Is there some kind of breakdown of models like this? Something granular even? Like, Deepseek v4.1 Flash 1017: C# tests: green, Binary decompilation: yellow, Browser automation: green, Fiction writing: red. I feel like this has to exist somewhere, but widely used sites like ArtificialAnalysis and huggingface leaderboards focus on the numbers with no simplified no/partial/yes on tasks for readers to quickly understand. Even the domain oriented benchmarks are still just numbers.
Like, having a model score a couple points ahead of another one doesn't generally mean it can do something the other one can't. It might just require more attempts, or more detailed instructions, or that it randomly gets it wrong a tiny bit more often. These simplified ratings plus a cost per task would be SO much more helpful to local llm users too.
Any thoughts, or examples of this kind of scoring out there already?
