Reasoning effort

Max effort is a pricing dimension. We report what vendors publish. We do not ship a reasoning-tax τ point estimate — that needs first-party probes with median and IQR, n≥15.

85/405 cannot disable thinking
274 reasoning supported
189 supported and optional

Effort ladders below are vendor labels (low / high / xhigh / max). An Elo without its effort level is not a fact — see methodology.
