In Midjourney, image generation speed is mainly determined by three rendering modes: Fast, Relax, and Turbo. They affect not only how long you wait, but also how you “spend your quota.” Below, we clearly explain the differences among these three modes so you can choose the right one for your project pace.
Fast Mode: Standard acceleration, the most convenient to use
Midjourney’s Fast mode consumes your Fast time (i.e., GPU minutes/quota), but you get a higher priority in the queue and the generation speed is relatively stable. For everyday commercial first drafts or when you need to iterate prompts repeatedly, Fast is the most worry-free choice. If you notice your Fast time dropping quickly, it’s usually because you’re upscaling frequently or doing multiple Vary iterations.
Relax Mode: Doesn’t burn Fast time, but you have to accept queuing
The key feature of Midjourney’s Relax mode is that it “doesn’t consume Fast time,” making it suitable for running drafts over long periods, batch-testing styles, or exploring ideas. The trade-off is slower speed, and queue time will fluctuate with platform load. Note that not all subscriptions include Relax: generally, entry-level tiers may not provide Relax, so whether you can use Midjourney’s Relax depends on your current plan.
Turbo Mode: Fastest, but burns through your quota much harder
Midjourney’s Turbo mode aims for the shortest wait times, making it suitable for deadline rushes, on-site generation, rapid direction confirmation, and other highly time-sensitive scenarios. Turbo typically consumes Fast time at a higher multiplier (often billed at a higher rate), so it’s not suitable for long sessions of “mass generation.” If you just want it a bit faster, use Fast first; only switch on Midjourney’s Turbo when you truly need to race against time.
How to switch modes: Using commands is faster than hunting for buttons
When using Midjourney in Discord, the most direct way to switch modes is to enter commands: /fast, /relax, /turbo. You can also check in Midjourney’s /settings to see whether the current mode is active and confirm whether your plan supports Relax. It’s recommended to verify the mode before each work session to avoid accidentally using Turbo and burning through your Fast time.
Selection tips: Decide along two lines—“timeliness” and “quota”
If you’re doing lots of trial and error in Midjourney: run drafts in Relax first, then switch to Fast for key versions for a more reliable workflow. If you’re doing final delivery upscales in Midjourney and need more controllable speed: Fast is more suitable. Only when there’s a clear moment of “I need images right now” is it recommended to switch Midjourney to Turbo, spending your quota on the most critical few generations.
