LLM Benchmarks & Leaderboards

Each benchmark below ranks large language models on a specific task — and pairs every score with the model's cost per million tokens, so you can see which model is the best value, not just the highest score.

Decision-model benchmarks

Decision models answer typed questions with calibrated probabilities instead of generating text. These boards rank them on accuracy, with calibration (ECE) and latency alongside. See all decision models.
