What is BYOK?

BYOK lets you bind your own Discord account (with an active paid Midjourney subscription) to your Legnext account. While bound:
  • Fast-mode image tasks — imagine, variation, upscale, reroll, blend, describe — execute on your own Midjourney account and consume no platform credits per task.
  • Everything else — video and edit/enhance tools — keeps running on the platform pool and is billed per task as usual. Your API calls don’t change either way.
  • Rent: BYOK costs 20,000 credits/month (20at20 at 1 = 1,000 credits), charged from your credit balance. The first month is charged when you bind; renewals are attempted automatically starting 3 days before each due date.

​
Before you bind

  1. The Discord account has an active paid Midjourney subscription.
  2. The account has sent at least one DM to the Midjourney bot (Discord requires an existing DM channel for the engine to deliver commands).
  3. You have the account’s Discord token: log in to discord.com in your browser → DevTools (F12) → Network → filter by api → click any request → copy the Authorization request header value.
A Discord token grants full control of the Discord account — never share it with anyone. Automating a user account may violate Discord’s Terms of Service and can lead to the account being permanently banned. We strongly recommend using a dedicated account rather than your main one.

​
Bind, manage, unbind

Everything lives in the dashboard under My MJ Account (/app/byok):
  • Bind: paste the Discord token. Your balance must cover the first month’s rent.
  • Status: the page shows the live state of your account (active, session expired, fast hours exhausted, etc.) pulled from the engine in real time, including operator guidance when something is wrong.
  • Update token: if Discord invalidates your session (status cookie_expired), paste a fresh token to recover — the account resumes automatically.
  • Unbind: returns you to pure pay-as-you-go. Rent already charged is not refunded; rebinding starts a new billing cycle.

​
Multiple accounts (pool)

You can bind more than one Midjourney account. Each bound account is billed its own 20,000 credits/month — rent scales linearly per account.
  • Tasks are routed to the least-busy healthy account in your pool (engine status active and rent current). If no account is usable, fast-mode image tasks fail with a 400 that names the most actionable fix (top up for a rent-due account, or update the token of an expired one) — they never silently fall back to platform-credit billing.
  • Your effective fast-image concurrency scales with the pool: max(6, min(account concurrency limit, 3 × usable accounts)).

Billing states

​
Failure states of your Midjourney account

While your account is in any non-active state, fast-mode image tasks are rejected with a clear 400 — they never silently fall back to platform-credit billing.

FAQ

No. Endpoints, parameters, and your API key stay the same. Binding only changes where fast-mode image tasks execute and how they’re billed.
Tasks queue engine-side and wait for your account (up to 1 hour). They are never moved to another account or the platform pool.
Yes. Each account is billed 20,000 credits/month separately, and fast-mode image tasks are routed to the least-busy healthy account in your pool. See “Multiple accounts (pool)” above.
Yes for everything outside the BYOK domain: video and edit tools bill normally from your credit balance. Fast-mode image tasks always run on your own account while bound — unbind if you want them back on the pool.
