Midjourney Rate Limits

Midjourney does not currently expose a public, metered HTTP API. Generations are scoped to Discord and the web app and are governed primarily by per-plan Fast GPU minute budgets and concurrent-job caps rather than per-second rate limits. Concurrency limits and Relax-mode queue behavior vary by tier.

Policies

Plan-bound concurrency
Each tier has a fixed maximum of concurrent Fast jobs; additional generations queue until a slot frees.
Relax mode degradation
Once Fast minutes are exhausted, supported tiers fall back to Relax mode (queued) until the next billing cycle or Fast top-up.
Stealth gating
Stealth Mode is a Pro / Mega entitlement, not a rate limit, but affects which generations are publicly visible.
