# Advanced Prompting

> Multi-prompts and weights, permutations, negative prompting, and rendered text — prompt-language features beyond the basics.

This page covers the prompt-language features that go beyond plain descriptive
text. Read [Prompting Basics](/getting-started/prompting-basics) first.

<Warning>
  Multi-prompt and permutation syntax is documented upstream by Midjourney but is
  **not** part of the backend validation spec behind the [image parameter
  matrix](/getting-started/image-parameters). Treat the behavior on this page as
  upstream-documented and verify it against your target model version before
  building on it.
</Warning>

## Multi-prompts

<Warning>
  **Version-gated: V6 family only.** Midjourney's current compatibility chart
  marks multi-prompting as unsupported on V7 and the V8 family — `::` weights on
  `--v 7` or `--v 8.x` are ignored or rejected upstream. Pin `--v 6.1` (or
  `--v 6`) when you use this syntax.
</Warning>

A double colon `::` splits a prompt into parts the model considers separately
before blending them. `space ship` gives you sci-fi spaceships; `space:: ship`
treats "space" and "ship" as distinct ideas — the result might be a boat
sailing through space.

```text theme={null}
space:: ship --v 6.1
```

### Prompt weights

Add a number right after `::` to control how strongly a part pulls the result.
`space::2 ship` makes space twice as influential as the ship. An omitted weight
defaults to `1`; decimals (`::0.5`) are supported on the V6 family.

```text theme={null}
still life painting::2 fruit::1 --v 6.1
```

### Negative weights

Weights can go negative to suppress a concept, with one hard rule: **the sum of
all weights in the prompt must stay positive** or the prompt is rejected.

```text theme={null}
still life painting:: fruit::-0.5   # 1 + (-0.5) = 0.5 ✓
still life painting:: fruit::-2     # 1 + (-2)  = -1   ✗ rejected
```

## Permutation prompts

Curly braces with comma-separated options expand one prompt into many:
`a {red, green, yellow} bird` produces three prompts, one per color. Multiple
brace sets multiply — `a {red, green} bird in the {jungle, desert}` produces
four — and sets can be nested. Escape a literal comma with a backslash:
`{red, pastel \, yellow}` expands to two options, the second being
`pastel, yellow`.

Permutations also work on parameters: `--v {8, 8.2}` fans out across versions.

<Note>
  Permutation expansion happens when the prompt is submitted — upstream, the bot
  confirms the count and runs each expansion as a separate job. Through the API,
  the safe pattern is to expand client-side and submit one task per combination:
  you control the exact task count, the per-task cost, and each task's lifecycle
  independently. See [Task lifecycle](/getting-started/task-lifecycle).
</Note>

## Negative prompting with `--no`

`--no` excludes elements without negation words leaking into the description.
Append it at the end with a comma-separated list:

```text theme={null}
still life gouache painting --no fruit, apple, pear
```

Two subtleties from upstream behavior:

* **`--no` is equivalent to a `-0.5` weight** on that element in a
  multi-prompt. It softens rather than surgically removes; for hard control,
  describe what you *do* want.
* **Every word is read independently.** `--no modern clothing` is parsed as
  "no modern" and "no clothing" — which can misfire moderation and rarely does
  what you meant. Put the clothing you want in the prompt text instead.

Support: `--no` works on v6 / v6.1 / v7 / v8 / v8.1 / v8.2 but is rejected on
niji 6 — see the [parameter matrix](/getting-started/image-parameters).

## Text inside images

To render words in the image itself, wrap them in **double quotation marks** —
single quotes and apostrophes do not work. Short Latin-alphabet phrases render
most reliably, and naming the container helps:

```text theme={null}
a pastel watercolor landscape with "imagine" written in the clouds --v 8.2
a cartoon manual with the words "read the docs" on the cover --v 8.2
```

## A note on image references

Reference parameters (`--sref`, `--oref`, `--cref`, `--iw`) are prompt-language
features too, but their version support is narrow and changes fast — `--cref`
is rejected across the entire v8 family, and `--oref` exists only on v8.0.
Rather than duplicate a moving target here, use the [parameter
matrix](/getting-started/image-parameters) as the source of truth for which
reference your target version accepts.
