Ideogram V3 Character
ideogram-ai/ideogram-v3/character generates imagery around a supplied character reference, preserving recognizable identity while changing scene, pose, styling, or composition. Ideogram V3 Character emphasizes identity consistency so a recurring person or designed character can appear across varied creative situations without being redefined each time. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.
For production work with ideogram-ai/ideogram-v3/character, it supports character campaigns, storyboards, creator assets, product mascots, and narrative sequences where recognizability must survive substantial visual variation. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.
Highlights
Character identity preservation keeps distinctive facial and design traits recognizable.
Scene variation places the same character into new environments, poses, and compositions.
Typography-aware design combines recurring characters with readable campaign or story text.
Style flexibility carries character identity across photographic, illustrated, and graphic treatments.
Pricing
| Rendering speed | Price per image |
|---|---|
| Turbo | $0.100 |
| Balanced | $0.150 |
| Quality | $0.200 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
