# Ideogram 4.5

ID: ideogram/ideogram-4.5
Type: image generation
Vendor: Ideogram
Released: 2026-09-30
Description: Ideogram 4.5 generates and edits images with reliable in-image text. Presets cover the official 1K and 2K sizes. An edit takes one source image and up to four references.

## Modes and inputs
- Text → Image (`txt->img`)
  - Prompt only, no input images
- Image → Image (`img->img`)
  - `as: "source"`: exactly 1 (required)
  - `as: "reference"`: up to 4
  - At most 5 inputs in total

Input roles, set in `inputs[].as` (omit it, or send `auto`, to let Mynth assign one):
- `source`: The image to edit
- `reference`: An image to take style or content from

## Output
- Aspect ratios: 1:1, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 8:5, 5:8, 16:9, 9:16, 2:1, 1:2, 3:1, 1:3, 12:5, 5:12, 8:3, 3:8, 23:9, 9:23, 22:9, 9:22. Other ratios snap to the closest one. Without `size` (or with `"auto"`), Mynth picks a ratio for the prompt.
- 4K: no
- Negative prompt: not supported (dropped, no error)

## Pricing (USD)
- Per image: $0.060
- Per input image: Free, charged once for each image it goes into
- Only successful results are charged.

## Usage
Set the request's `model` field to `ideogram/ideogram-4.5`. Always pass it explicitly.
