How parameters work
A parameter is a short instruction at the end of the prompt, starting with two dashes. On the Midjourney website most of them are also sliders and buttons in the settings panel; typing them does the same thing.
Everything here is for V8.2, the default model since July 2026.
The ones you use every day
| Parameter | What it does | Range · default |
|---|---|---|
| --ar | The shape of the image. 16:9 for films, 9:16 for reels. | Whole numbers · 1:1 |
| --raw | Less of Midjourney’s own styling, so the image follows your words more closely. | On or off |
| --stylize (--s) | How much of Midjourney’s taste is added. | 0–1000 · 100 |
| --chaos (--c) | How different the four results are from each other. | 0–100 · 0 |
| --seed | Starts from the same point, so you can repeat a result or change one thing at a time. | 0–4294967295 |
| --no | Things to leave out, separated by commas. | Words |
For a consistent film
| Parameter | What it does | Range · default |
|---|---|---|
| --sref | Copies the look of an image or a style code. | Link or code |
| --sw | How strongly the style reference is applied. | 0–1000 · 100 |
| --p | Uses your personal profile or a moodboard. | Profile ID |
| --iw | How much an image prompt counts against the text. | 0–3 · 1 |
| Edit Model | Keeps a character or object the same, from up to four reference images. | V8.1 and V8.2 |
How to use these together is in Lock a look in Midjourney.
Useful now and then
- --weird (--w), 0–3000: stranger, less expected results.
- --tile: an image that repeats seamlessly, for textures and patterns.
- --repeat (--r): runs the same prompt several times. The limit depends on your plan.
- --niji 7: the anime model.
No longer in V8
- --cref / --cw and --oref / --ow: character and omni references. Replaced by the Edit Model.
- --q / --quality: not supported.
- --stop: a legacy feature of V6 and earlier.
- Multi-prompts with :: and Turbo mode: not available.
If a tutorial depends on one of these, it was written for an older version.
Three starting points
Film still [shot], [style line] --ar 16:9 --raw --s 50 Reel frame [shot], [style line] --ar 9:16 --raw --s 100 Exploring [shot] --ar 16:9 --c 30 --s 250
Change one parameter at a time and keep the same seed. That is the only way to see what each one really does.
Tools, prices and platform rules change often. Everything here was checked in November 2026; confirm on the tool’s own page before you rely on it.
