## What it does

This skill guides coding assistants through calling two text-to-image endpoints. The native `POST /api/v1/image/generate` route offers full control over negative prompts, CFG scale, seeds, style references, and up to four image variants. The OpenAI-compatible `POST /api/v1/images/generations` route functions as an in-place swap for existing OpenAI SDK implementations.

Venice enforces a strict request schema: any unknown field triggers a `400` response. Calling the API requires a `$VENICE_API_KEY`. Parameter support varies by model: pixel dimensions `width` and `height` accept values up to 1280 on supported engines, while others require `aspect_ratio`. The optional `enhance_prompt` flag rewrites prompts for extra detail, adding up to 30 seconds of latency and a $0.04 fee.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-image-generate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/venice-image-generate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/venice-image-generate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-image-generate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/venice-image-generate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-image-generate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/venice-image-generate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install veniceai/skills venice-image-generate
```

2. **Manually: put the files in place**
- File: `.github/skills/venice-image-generate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-image-generate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/veniceai/skills --path skills/venice-image-generate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/venice-image-generate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-image-generate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/veniceai/skills/tree/HEAD/skills/venice-image-generate/SKILL.md

## When to use it
- send requests to the native Venice image generation API
- replace OpenAI image generation endpoints with zero SDK changes
- retrieve available aesthetic presets via GET /api/v1/image/styles
- guide visual rendering using reference images in style_references

## Example prompts
- Generate a mountain landscape at sunset using Venice API with a 16:9 aspect ratio and z-image-turbo.
- Fetch the available style presets from GET /api/v1/image/styles and list their exact names.
- Create four webp image variants with seed 123456789 using the Venice-native endpoint.

# Venice Image Generation

Two text-to-image endpoints:

1. **`POST /api/v1/image/generate`** — Venice-native, full control (negative prompts, CFG, seed, style presets/references, quality, up to 4 variants).
2. **`POST /api/v1/images/generations`** — OpenAI-compatible, fewer knobs but drop-in for the OpenAI SDK.

Plus:

- **`GET /api/v1/image/styles`** — list of style preset names for `style_preset`. No auth required.

For editing / upscaling / multi-image / background removal, see [`venice-image-edit`](../venice-image-edit/SKILL.md).

## Use when

- You need to generate images from text prompts.
- You need multiple variants in one call.
- You're porting from OpenAI's `images.generate` and want a zero-change SDK swap.
- You want to browse style presets before committing to one.
- You want generated images to match the look of existing images (`style_references`).

## `/image/generate` — Venice-native

### Request

```bash
curl https://api.venice.ai/api/v1/image/generate \
  -H "Authorization: Bearer $VENICE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "z-image-turbo",
    "prompt": "A beautiful sunset over a mountain range",
    "width": 1024,
    "height": 1024,
    "cfg_scale": 7.5,
    "seed": 123456789,
    "variants": 1,
    "format": "webp",
    "style_preset": "3D Model",
    "safe_mode": true
  }'
```

The request schema is **strict**: unknown fields are rejected with `400`.

### Fields

| Field | Type | Default | Notes |
|---|---|---|---|
| `model` | string | — | **Required.** Image model ID from `GET /models?type=image`. Unknown IDs return `404` (with a suggestion); retired IDs return `404` naming the replacement when one exists. |
| `prompt` | string | — | **Required.** Non-blank. Max `constraints.promptCharacterLimit` for the model (1,500 – 32,768 today). |
| `negative_prompt` | string | — | What *not* to show. Same character cap as `prompt`. Only used by some models today (e.g. `venice-sd35`, `lustify-*`, `wai-Illustrious`, `qwen-image-2`, `qwen-image-2-pro`, `qwen-image-3`, `qwen-image-3-pro`, `wan-2-7-*`). Silently dropped everywhere else, including `z-image-turbo` and `chroma`. |
