Each evaluation is attempted up to 4 times. Success Rate is the percentage of evals that passed on at least one attempt; First-Try Rate is the percentage that passed on the first attempt, used to break ties between models with the same success rate. Avg Duration is the mean time an agent took per eval. Avg List Cost is the mean cost per eval, estimated from the tokens each run used at the provider's public list price, so it's a relative guide and not a bill: your rate depends on caching, discounts and subscription plans. Expand a row to see per-eval results, where a 1/3 badge means the eval failed twice before passing.
