Each struck-through figure is that row's reference list price and links to the page that publishes it, so every line can be checked. "At list" means we sell at the reference price; "mixed" means we are below it on one side and above on the other. Every row checkable, every model verifiable →

New accounts get $0.05 free credit with no card, usable on 5 starter chat models in browser chat or through the API with your account key. API access also includes five speech models; top up from $5 to unlock the rest. Browser chat also has a separate allowance of 5 free messages. And your first credit purchase is matched 100%, up to $50 in bonus credits. The bonus is added to your balance the next time you top up (any amount from $5): pay $20, then top up $5 later, and $20 of bonus arrives with it. A larger first payment still receives the $50 maximum. One per customer and payment card; standard pay-as-you-go after that.
