Character design with genmedia

Use this skill when the user wants to create, refine, or preserve a character. Load the reference files when needed:
  • references/anchor-system.md
  • references/prompt-patterns.md
  • references/examples.md
Load 
model-routing
alongside this skill for default endpoint choices.
The main objective is consistency. Keep the character anchor stable and change only the requested scene, expression, outfit, camera, or action.

Inputs to collect

Only ask for missing inputs that affect identity or model routing.
  • Character type: realistic human, stylized, anime, mascot, fantasy, sci-fi.
  • Identity anchor: age range, face shape, hair, eyes, build, posture, marks.
  • Style: photographic, 3D, illustration, manga, comic, game concept art.
  • Needed outputs: portrait, full body, turnaround, expression sheet, outfit set, action still, video shot, edit of an existing character.
  • References: source image, approved design, costume, pose, style board.
  • Consistency level: exploratory, pitch-ready, production continuity.
  • Model preference: use 
    model-routing
    defaults unless the user names a model or the job needs a quality/cost tradeoff decision.

Genmedia workflow

  1. Start from routed endpoint IDs.
    bash
    genmedia models --endpoint_id openai/gpt-image-2 --json
genmedia models --endpoint_id fal-ai/nano-banana-pro/edit --json
genmedia models --endpoint_id bytedance/seedance-2.0/image-to-video --json
genmedia models --endpoint_id veed/fabric-1.0 --json
    Use text search only as fallback discovery for an unsupported role:
    bash
    genmedia docs "consistent character generation" --json
genmedia models "image editing character consistency" --json
  2. Inspect schema before each endpoint run.
    bash
    genmedia schema <endpoint_id> --json
genmedia pricing <endpoint_id> --json
  3. Upload references.
    bash
    genmedia upload ./character-reference.png --json
genmedia upload ./costume-reference.png --json
  4. Run stills or sheets with download.
    bash
    genmedia run <endpoint_id> \
  --prompt "<anchor + variable prompt>" \
  --image_url "<reference url if supported>" \
  --download "./outputs/characters/{request_id}_{index}.{ext}" \
  --json
  5. Run video async.
    bash
    genmedia run <endpoint_id> \
  --prompt "<anchor + shot action>" \
  --image_url "<approved character frame if supported>" \
  --async \
  --json

genmedia status <endpoint_id> <request_id> \
  --download "./outputs/characters/{request_id}_{index}.{ext}" \
  --json
Use only schema-supported fields. If the model supports seed, reference image, image strength, multiple image inputs, or negative prompt, use them deliberately and record what was used.

Character anchor

Create a short immutable anchor before generating.
text
CHARACTER ANCHOR:
[name or codename], [age range], [face shape], [eye shape and color],
[nose and lips], [skin tone and distinguishing marks], [hair color, texture,
style], [body build and posture], [signature clothing or silhouette],
[style target]
Then add a variable block for the current shot.
text
SHOT VARIABLE:
[expression], [pose/action], [outfit changes if allowed], [environment],
[camera/framing], [lighting], [mood]
Never rewrite the anchor casually. If a result changes identity, strengthen the anchor or switch to a reference/edit workflow instead of adding more style words.

Model routing

  • New character concept with maximum consistency: use 
    openai/gpt-image-2
    .
  • Premium but cheaper image option: use 
    fal-ai/nano-banana-pro
    or 
    fal-ai/nano-banana-2
    .
  • Fast exploratory drafts: use 
    fal-ai/flux-2/klein/9b
    .
  • Consistent sheet from an approved character: use 
    openai/gpt-image-2
    first; if editing an existing image, inspect 
    openai/gpt-image-2/edit
    .
  • Outfit variations and character edits: use 
    fal-ai/nano-banana-pro/edit
    , then 
    openai/gpt-image-2/edit
    , then 
    fal-ai/bytedance/seedream/v5/lite/edit
    .
  • Expression sheet: one approved face reference, multiple controlled expression prompts.
  • Character video: approved still frame first, then 
    bytedance/seedance-2.0/image-to-video
    for final quality.
  • Fast video drafts: use 
    xai/grok-imagine-video/image-to-video
    .
  • Talking avatar or lip-sync: use 
    veed/fabric-1.0
    , 
    veed/fabric-1.0/text
    , or 
    fal-ai/creatify/aurora
    .

Quality bar

Reject or retry when:
  • Face shape, eye spacing, hairstyle, marks, or body build drift.
  • Outfit changes when the prompt says only expression or pose should change.
  • The sheet mixes styles across panels.
  • Hands or props distract from the requested design task.
  • Video motion changes age, face, costume, or silhouette.
Return downloaded paths and include the anchor used so future prompts can reuse the same identity.
