Inputs to collect

• 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

Character anchor

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]

SHOT VARIABLE:
[expression], [pose/action], [outfit changes if allowed], [environment],
[camera/framing], [lighting], [mood]

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

• 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.
