Reasoning effort was pinned to max for every model whose lane exposes a control OpenAI-style reasoning effort , Anthropic extended thinking, Gemini thinking config . Models marked vendor default on the interactive board expose no such control and ran as shipped. A model's mean score averages its graded tasks; a generation failure counts as 0. Cost per task is estimated from each model's published per-token pricing "—" where pricing isn't public , so treat it as directional, not billing-exact.
