The Value Frontier

Price vs Intelligence — lower price, higher score is better.

Fast and Smart

Speed vs Intelligence — higher on both axes is better.

Efficiency

Speed vs Price — faster and cheaper is better.

SWE-rebench

Daily rankings from SWE-rebench, a benchmark designed to fairly compare LLM capabilities on real-world software engineering tasks. Unlike other evaluations, it uses a standardized scaffolding for all models, continuously updates its dataset to prevent contamination, and runs each model five times to account for stochastic variance.
