Earth-Bench benchmark leaderboard

What this metric means. For each task, the share of a model's attempts that passed every check; then the average over the tasks. Tasks with no decided attempt yet are left out.

What this metric means. Average tokens per attempt, as reported by the provider: input the model read (split into new and cached input) and output it wrote, which includes its reasoning.

Compare with care. Models use different tokenisers, so the same text is a different number of tokens for different models. Use token counts to see how much work each model did, and cost to compare spending.

What cost is measuring. The average cost of one attempt at a task: tokens reported by the provider multiplied by the serving provider's published list prices, with cached input at its own price. Failed attempts count, so a model that fails slowly and expensively is not flattered.

How to read this chart. Lower is better. Costs are pay-per-token list prices, not any discount or credit a customer might have.

What execution time is measuring. Agent wall time per attempt, from the agent's first model call to its last action: model thinking, waiting for the provider and running commands. Sandbox start-up and grading are not included.

How to read this chart. Lower is better. An attempt that reaches the task's time limit scores 0 and counts at the limit.
