What are Midjourney fast hours?

Midjourney fast hours refer to the GPU time assigned to a user each month, depending on their subscription plan with Midjourney. Fast hours are essentially priority access to Midjourney's processing power and put the user at the front of the image generation line.

Different subscription plans have different amounts of monthly GPU time. The Standard plan gets 15 hours of fast generations, while the Pro plan receives 30 hours of fast generations. Unused monthly fast GPU time does not roll over to the next month.

Paid accounts have the option to purchase additional fast hours at $4/hr.. If a user runs out of fast hours, they will either need to purchase additional hours or wait for the billing cycle to renew.
