What is a credit?
1 credit is roughly equal to 1 short Haiku message. Haiku is fast and lightweight, so it uses credits at the lowest rate — ideal for quick questions and daily study.
Longer messages and more complex tasks consume more credits than short ones, since more tokens are processed on each turn.
