class RubyLLM::Model::PricingTier

A PricingTier holds the prices a model charges within one billing tier, standard or batch. Each price is in USD per one million tokens. Prices missing from the registry read as nil. A zero price means the usage is free.

Instances come from PricingCategory#standard and PricingCategory#batch:

model = RubyLLM.models.find "claude-sonnet-4-6"
tier  = model.pricing.text_tokens.standard
tier.input_per_million  # => 3
tier.output_per_million # => 15

Constants

ATTRIBUTES: The names of the price readers a tier responds to.
