reference — every parameter
Every Midjourney parameter, with its range and default
The lookup table. Every flag with its short alias, what it accepts, what it defaults to, and which of them are mutually incompatible.
Parameters go at the end of a prompt, after the description — see prompt structure for the placement rules. This page is the lookup table: what each flag accepts, and what happens if you leave it out.

Framing and output
| Parameter | Alias | Accepts | Default |
|---|---|---|---|
--aspect | --ar | two whole numbers, w:h — no decimals | 1:1 |
--hd | — | 2048px generation on V8.1 and later, no upscale step | off (--sd, 1024px) |
--quality | --q | V7: 1, 2, 4 · V6: 0.5, 1, 2 — multiplies GPU time | 1 |
--tile | — | seamless repeating pattern | off |
--repeat | --r | run the same prompt several times | off |
Style and how literal the model is
| Parameter | Alias | Accepts | Default |
|---|---|---|---|
--stylize | --s | 0–1000 — low is literal, high is artistic | 100 |
--raw | — | turns off Midjourney’s default styling | off |
--chaos | --c | 0–100 — how different the four results are from each other | 0 |
--weird | --w | 0–3000 — experimental strangeness | 0 |
--no | — | comma-separated things to exclude | nothing excluded |
References — pointing at images instead of describing
| Parameter | Alias | Accepts | Default |
|---|---|---|---|
--sref | — | a style code, an image URL, several of either, or “random” | none |
--sw | — | 0–1000 — how strongly the style reference applies | 100 |
--sv | — | which style-reference algorithm — V7: 1–6, V6: 1–4 | V7: 6 · V6: 4 |
--profile | --p | one or more personalization / moodboard codes, space separated | none (or your defaults, if switched on) |
--oref | — | an image URL whose subject should carry across | none |
--iw | — | 0–3 (Niji 7: 0–2) — weight of an image prompt | 1 |
Which model, and how it runs
| Parameter | Alias | Accepts | Default |
|---|---|---|---|
--version | --v | a model version number | whatever your account default is |
--niji | — | the anime-focused model — 6 or 7 | not used |
--seed | — | a whole number, 0–4294967295 | random every run |
--draft | — | draft images at roughly half the GPU cost | off |
--fast · --relax · --turbo | — | GPU speed for this one job | your account setting |
--stealth · --public | — | whether the result is private or public | your plan’s setting |
What cannot be combined
Most parameters ignore each other happily. The exceptions are worth knowing, because a flag that is silently dropped looks exactly like a flag that did nothing:
| Combination | What happens |
|---|---|
Moodboards with --sw or --sv | not compatible — those two are for style references only |
--weird with --seed | not fully compatible; treat a locked seed as unreliable here |
--seed in Turbo mode | seed locking is not reliable — Turbo optimises for speed |
Image-only prompts with --stylize or --weird | not supported without any text in the prompt |
--q 4 with --oref | not compatible |
--sref random with --sv other than 4 or 6 | random and style codes only work on those two |
For flags belonging to versions that are no longer served, Midjourney keeps a legacy features article. And every prompt in the collection here is published with its parameters parsed out into fields, if you would rather read real tails than a table.
