Cost is the recorded list price for the calls made, per 1,000 queries and per 1,000 correct answers. * The runner and published data are open in [openbenchmarks-labs/factual-lookup-company-news-search ↗](https://github.com/openbenchmarks-labs/factual-lookup-company-news-search) and [openbenchmarks/OB-News-Websearch ↗](https://huggingface.co/datasets/openbenchmarks/OB-News-Websearch).
