$10 / 1M audio input tokens

per 1M tokens, by modality — billed by the session's real usage across every response.done event, not a flat per-minute or per-call rate

Token type	Input	Cached input	Output
Text	$0.6	$0.06	$2.4
Audio	$10	$0.3	$20
Image	$0.8	$0.3	$0

+ VideoRouter platform fee: 2% of provider cost — billed as its own line, never blended into the rates above.
