We tested 131 models across 44 benchmarks on success rates, latency and cost per task.
Each point is a model. The dashed line joins the models that no other model beats on both cost and score.

Models are ranked by the AIM LLM Index, a weighted average of AIMultiple's own benchmarks and public benchmarks on coding, reasoning, finance and agentic tasks. Prices are the lowest list API price across providers. Cost per task comes from each benchmark's token counts or published costs; the default view averages it over the benchmarks a model has a cost on.
