Context cliffs

Name: Undominated.ai AI model price and capability catalogue
License: https://undominated.ai/methodology/

Every published context-tier step function in the catalogue. Ladders keep every rung — a flattened ladder once mispriced five models by up to 2×.

5 of 55 carry more than one rung. Multipliers are input $/M at the rung ÷ headline input $/M. Condition: OpenRouter-published tiers in the catalogue payload.
