***
## Basic Parameters
### Aspect Ratio `--ar`
Sets the image aspect ratio. Only integer ratios are supported.
```
a cat --ar 16:9
```
Common values: `1:1`, `4:3`, `3:2`, `16:9`, `9:16`, `2:3`
### Chaos `--chaos` / `--c`
Controls the diversity of generated results. Higher values produce greater differences among the 4 images.
```
a cat --c 50
```
| Range | Effect |
| ------ | ------------------------------------------------ |
| 0 | 4 images are very similar (default) |
| 1-50 | Moderate diversity |
| 50-100 | Highly random, suitable for creative exploration |
### Negative Prompt `--no`
Excludes unwanted elements, equivalent to -0.5 weight. Supports multiple keywords.
```
vibrant tulip field --no red,shadows
```
V7 does not support the `::` multi-prompt syntax. You can only use `--no` to exclude unwanted elements.
### Quality `--quality` / `--q`
Controls generation detail level.
```
a cat --q 2
```
| Value | Description |
| ----- | ---------------------------------------------- |
| 1 | Default, with optimized hand coherence |
| 2 | Uses the pre-optimization V7 model |
| 4 | Experimental mode (incompatible with `--oref`) |
Higher quality values consume more GPU resources and increase costs accordingly.
### Seed `--seed`
Fixes the initial random state for comparison testing.
```
a cat --seed 23453422
```
* Range: 0 - 4294967295
* Same seed + same prompt → similar (not identical) results
* Not applicable in turbo speed mode
### Stylize `--stylize` / `--s`
Adjusts the balance between realism and artistic style.
```
a cat --s 500
```
| Range | Effect |
| -------- | ------------------------------------------------------- |
| 0-250 | Realistic style, faithful to the prompt |
| 250-750 | Balanced |
| 750-1000 | Strong artistic expression, bold colors and composition |
### Weird `--weird` / `--w`
Introduces unconventional and surreal elements.
```
space landscape --w 800
```
| Range | Effect |
| --------- | ---------------------------------- |
| 10-300 | Slightly weird |
| 300-1000 | Noticeably unconventional elements |
| 1000-3000 | Extreme surrealism and abstraction |
### Experimental `--exp` (V7 Exclusive)
Similar to `--stylize` but stackable, generating more detailed, dynamic, and creative images.
```
a cat --exp 25
```
* Recommended values: 5, 10, 25, 50, 100
* Noticeable effect changes from 5-50, diminishing returns from 50-100
* May override `--stylize` effects above 25-50
### Raw Mode `--raw`
Disables default beautification for stricter adherence to prompt details. Suitable for photorealism or precise control scenarios.
```
product photo --raw
```
### Tile `--tile`
Generates seamlessly repeating patterns (seamless in all four directions), suitable for textures, wallpapers, and fabric designs.
```
brick wall texture --tile
```
***
## Image Reference Parameters
### Image Prompt
Place image URLs at the **beginning** of the prompt to influence the generated content.
```
https://example.com/ref.jpg text description --iw 1.5
```
**Valid combination rules:**
| Combination | Valid? |
| ---------------------------- | ---------------------- |
| 1 image + no text | ❌ Invalid (will error) |
| 1 image + text description | ✅ Valid |
| 2+ images + no text | ✅ Valid |
| 2+ images + text description | ✅ Valid |
* Maximum 20 image prompts
* Supported formats: `.png`, `.gif`, `.webp`, `.jpg`, `.jpeg`
### Image Weight `--iw`
Controls the influence of image prompts on the result. Range 0 - 3, default 1. Higher values produce results closer to the reference image.
```
https://example.com/ref.jpg watercolor landscape --iw 2.0
```
### Style Reference `--sref`
Matches the visual style (colors, textures, lighting) of the reference image without copying content. **Must be used with a text prompt**.
```
a cat --sref https://example.com/style.jpg
```
* Multiple supported: `--sref URL1 URL2`
* Weight allocation supported: `--sref URL1::2 URL2::1` (Note: the `::` here is weight syntax within the sref parameter, which is a different concept from the multi-prompt `::` separator that V7 does not support)
* Random style supported: `--sref random` (returns a numeric code after generation, reusable)
* Maximum 20 srefs
### Style Weight `--sw`
Controls the influence of the style reference. Range 0 - 1000, default 100.
```
a cat --sref https://example.com/style.jpg --sw 500
```
### Style Version `--sv`
Switches the style reference algorithm version.
| Version | Characteristics |
| ------- | -------------------------------------- |
| 1 | Original algorithm, more "atmospheric" |
| 2 | Second iteration |
| 3 | Updated version of v1 |
| 4 | Updated version of v2 (**default**) |
| 5 | New in V7 |
| 6 | New in V7 |
### Object Reference `--oref` (V7 Exclusive)
Places characters, objects, vehicles, or non-human creatures from the reference image into a new image. **Must be used with a text prompt**.
```
a duckling holding a magic wand --oref https://example.com/duck.jpg
```
Using object reference consumes 2x GPU time, doubling the cost. Only one reference image can be used.
### Object Reference Weight `--ow` (V7 Exclusive)
Range 1 - 1000, default 100. Recommended to keep below 400, otherwise results may be unpredictable. High `--stylize` values may require higher `--ow` to compensate.
```
duckling --oref https://example.com/duck.jpg --ow 300
```
***
## Speed Modes
Speed mode is controlled via the API's `model_params.speed` field, which is automatically injected into the prompt.
| Mode | Description | Cost |
| ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `draft` | 10x faster, lower quality, can be enhanced later with [mj-v7-enhance](/en/api-manual/image-series/midjourney/mj-v7-enhance). **Image generation endpoint only** | Lowest |
| `fast` | Standard quality (default) | Standard |
| `turbo` | Maximum speed | \~2x fast |
***
## Dependencies
The following parameters require other parameters to take effect:
| Parameter | Prerequisite |
| ------------------- | --------------------- |
| `--sv`, `--sw` | Requires `--sref` |
| `--iw` | Requires image prompt |
| `--ow` | Requires `--oref` |
| `--sref`, `--oref` | Requires text prompt |
| Single image prompt | Requires text prompt |
***
## Conflicts
| Parameter A | Parameter B | Description |
| ----------------- | ----------------------- | ----------------------------------------------------------- |
| `--oref` | draft / turbo speed | Object reference only compatible with fast mode |
| `--oref` | `--q 4` | Quality 4 is incompatible with object reference |
| `--oref` | inpaint/pan/outpaint | Object reference images cannot be used for these operations |
| `--draft` | `--tile` | Draft mode does not support tiling |
| Image-only prompt | `--stylize` / `--weird` | Incompatible without text |
When `--exp` exceeds 25-50, it will suppress the effect of `--stylize`. It is recommended to use lower exp values (5-25) when combining them.
***
## Unsupported Parameters in V7
| Parameter | Description |
| ------------------------ | --------------------------------------------------------- |
| `--stop` | Not supported in V7 |
| `--cref` / `--cw` | Use `--oref` object reference instead |
| `--relax` | V7 does not support relax mode |
| `--repeat` / `--r` | Not supported via API |
| `--p` (personalize) | Not supported via API |
| `{}` permutations | Not supported via API |
| `--stealth` / `--public` | Not supported by API (images are not publicly accessible) |
| Multi-prompt `::` | Not supported in V7 |
***
## Prompt Format Guidelines
### Basic Structure
```
[image URL] text description --param1 value1 --param2 value2
```
### Writing Rules
* Parameters go at the **end** of the text prompt
* A **space** is required before `--`
* Do not use punctuation in parameters
* No text can follow after parameters
### Examples
```text Correct theme={null}
a yellow Persian cat --ar 1:2 --s 500
```
```text Incorrect theme={null}
a yellow Persian cat--ar 2:3 ← missing space before --
a yellow Persian cat - - ar 2:3 ← space between --
a yellow Persian cat --ar 2:3, --s 50 ← punctuation in parameters
a yellow Persian cat --ar 2:3 more description ← text after parameters
```
