Simple pricing, while you figure out what to build.
Cepheus is free while you explore a problem — there is nothing to buy yet. AI is metered in credits rather than sold as "unlimited", because every AI action costs real money to run — and you should always know what you have left.

What an AI credit buys
AI runs only when you ask for it. Nothing in Cepheus calls a model while you browse, and results are stored so reopening a page never costs you again.

Payment processing is not connected yet, so nothing is charged and no card is collected. Everything that is not AI keeps working when your credits run out.
