The ≈ numbers use Balanced credit rates on every plan and count one kind of task at a time; credits are one shared pool. Fast uses fewer credits, and longer or harder work uses more. Yearly plans are billed once every 12 months at the price of 10 months. AI credits are added monthly and do not roll over. Separately purchased credits stay as long as you sign in at least once a year. Prices exclude tax.

Three modes, one pool of credits

You choose the mode for each request. Not sure? Use Balanced.
