Can I use CharacterOS characters commercially?

Yes! Pro plan users receive a full commercial license for all generated characters. You can use them in manga, webtoons, games, merchandise, social media, and any commercial project without restrictions. Free plan generations are for personal use only.

Does it work with anime and manga art styles?

Absolutely — anime and manga are our specialty. CharacterOS was trained on a massive dataset of anime, manga, and illustration art styles. It handles everything from classic shōnen and shōjo to cyberpunk, isekai, and slice-of-life styles with exceptional fidelity.

How consistent is the character identity, really?

We achieve 99.7% identity consistency measured by our Character DNA similarity score. This means face geometry, hair signature, eye shape, proportions, and overall style remain stable across emotions, angles, and scenes. We run automated consistency checks on every generation.

Can I upload my own original art?

Yes! You can upload any original character art as the DNA source — PNG, JPG, sketch, or digital painting. Our AI extracts the identity traits and locks them. You retain full ownership of your uploaded art. We never use uploaded art for training without explicit written consent.

How fast is generation?

Standard generations complete in 8–15 seconds. Pro plan users get priority queuing, typically 3–6 seconds. Enterprise customers can access dedicated processing and batch generation.

Is there an API available?

A REST API is available for Enterprise customers. It supports character DNA creation, expression generation, angle variations, and batch operations. Contact sales for API access, documentation, and SDKs.

What art styles are supported?

CharacterOS supports anime, manga, western cartoon, semi-realistic, chibi, moe, cyberpunk, fantasy, and sketch styles. You can also mix styles or apply style packs (Pro+) to transform your character into different aesthetic universes while preserving their core identity.

GPT Image Character Consistency

June 10, 2026

GPT Image and Identity

GPT Image brings conversational control to image generation—great for iteration but risky for identity unless you engineer consistency. Users describe scenes in natural language; the model interprets holistically. Identity must be reinforced each turn.

Treat GPT Image as a scene director, not a character database. Your character database should live in CharacterOS DNA and exported reference grids.

Common Drift Patterns

Session drift: character changes over twenty prompts. Scene drift: new background alters face. Emotion drift: angry face has different bone structure than neutral. Tool handoff drift: GPT Image concept does not match Midjourney final.

Document which failure mode you see most—fixes differ. Session drift needs persistent references; emotion drift needs expression-specific DNA locks.

Reference Strategy

Attach the same 2–4 reference images every generation batch: neutral front, three-quarter, profile, full body if needed. Write a short DNA block in prompts: fixed traits only, no scene language mixed in.

CharacterOS exports are sized for this workflow—consistent lighting across references so the model does not confuse identity with exposure changes.

CharacterOS Integration

Build DNA in CharacterOS → export expression grid → use as GPT Image references → generate scene variations in CharacterOS Scene Studio when chat drift persists → return to GPT Image only for experimental shots with cref discipline.

Many creators use GPT Image for brainstorming words and CharacterOS for canonical assets.

Workflow Checklist

Lock DNA. 2) Export references. 3) Fixed prompt identity block. 4) Change one variable per iteration. 5) Compare to grid before accepting. 6) Archive seeds and settings. 7) Never ship without grid check.

Frequently Asked Questions

Does GPT Image remember my character?

Not reliably across sessions; use external DNA and reference images instead of assuming memory.

How many reference images should I use?

Two to four high-quality consistent references usually outperform one or ten noisy images.
