Ideogram Image Generation Compared: How to Choose Among Six Core Models

II. Six Models Deep Dive

Model 1: character-edit

Edit a masked region on a base portrait while locking identity to a separate reference still—ideal for expression tweaks, wardrobe details, or localized refinements.

{
  "model": "ideogram-character-edit",
  "prompt": "Fill the masked region (max 5000 characters)",
  "imageUrl": "Base image URL",
  "maskUrl": "Mask URL (white = edit, black = keep)",
  "referenceImageUrls": ["Character reference (1 image)"],
  "renderingSpeed": "BALANCED",
  "expandPrompt": true,
  "numImages": "1",
  "seed": 0
}

Mechanics: upload base image, mask (same dimensions), and one character reference. FuseAI Tools accepts JPG/PNG/WEBP up to 10MB per asset.

Best for: eye/expression changes, localized outfit edits, identity-safe inpainting.

Model 2: character-remix

Keep a character recognizable while remixing scene and context from an existing frame plus prompt. strength balances fidelity to the source image vs creative freedom.

{
  "model": "ideogram-character-remix",
  "prompt": "Scene remix brief (max 5000 characters)",
  "imageUrl": "Base image URL",
  "referenceImageUrls": ["Character reference (1 image)"],
  "renderingSpeed": "BALANCED",
  "style": "AUTO",
  "expandPrompt": true,
  "imageSize": "square_hd",
  "numImages": "1",
  "strength": 0.8,
  "negativePrompt": "",
  "seed": 0
}

Strength guide: higher (0.8–1.0) preserves more of the original frame; lower (0.1–0.5) follows the prompt more aggressively.

Best for: background swaps, environmental storytelling, “same hero, new location.”

Model 3: character

Place a character into a brand-new scene using only a reference still and text—no base image required.

{
  "model": "ideogram-character",
  "prompt": "Scene description (max 5000 characters)",
  "referenceImageUrls": ["Character reference (1 image)"],
  "renderingSpeed": "BALANCED",
  "style": "AUTO",
  "expandPrompt": true,
  "imageSize": "square_hd",
  "numImages": "1",
  "negativePrompt": "",
  "seed": 0
}

vs character-remix:

Best for: character posters, multi-scene campaigns, net-new compositions anchored to one face.

Model 4: v3-text-to-image

General-purpose generation from text with style, speed, size, MagicPrompt expansion, and optional negative prompt.

{
  "model": "ideogram-v3-text-to-image",
  "prompt": "Image description (max 5000 characters)",
  "renderingSpeed": "BALANCED",
  "style": "AUTO",
  "expandPrompt": true,
  "imageSize": "square_hd",
  "negativePrompt": "",
  "seed": 0
}

Style options: AUTO, GENERAL, REALISTIC, DESIGN.

Rendering speed: TURBO (fastest), BALANCED (default), QUALITY (slowest, highest fidelity).

Image size examples: square, square_hd, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9.

Best for: concept art, product sketches, marketing stills without a reference photo.

Route: /home/ideogram/v3-text-to-image

Model 5: v3-edit

Mask-driven inpainting without a character reference—swap objects, fix backgrounds, or remove artifacts in a selected region.

{
  "model": "ideogram-v3-edit",
  "prompt": "What to paint inside the mask (max 5000 characters)",
  "imageUrl": "Source image URL",
  "maskUrl": "Mask URL",
  "renderingSpeed": "BALANCED",
  "expandPrompt": true,
  "seed": 0
}

vs character-edit: v3-edit is identity-agnostic; character-edit adds referenceImageUrls so faces stay on-model.

Best for: prop swaps, watermark cleanup, localized retouching on non-character assets.

Route: /home/ideogram/v3-edit

Model 6: v3-remix

Transform an entire image toward a new style or content direction—no mask, no character reference, with adjustable strength.

{
  "model": "ideogram-v3-remix",
  "prompt": "Remix direction (max 5000 characters)",
  "imageUrl": "Source image URL",
  "renderingSpeed": "BALANCED",
  "style": "AUTO",
  "expandPrompt": true,
  "imageSize": "square_hd",
  "numImages": "1",
  "strength": 0.8,
  "negativePrompt": "",
  "seed": 0
}

vs character-remix: v3-remix does not take a character reference; use character-remix when facial consistency matters.

Best for: material changes, illustration styles, holistic art-direction shifts.
