AI Character Design

Generate game character concepts, turnaround sheets, and design art using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": "Design a fantasy RPG rogue character: a lithe elven woman with short silver hair and violet eyes, wearing dark leather armor with buckles and straps, a hooded cloak, twin daggers at her belt, and soft boots. Character concept art, full body front view, neutral A-pose, detailed clothing design, digital painting, dark moody background"
      }
    ],
    "stream": false
  }'

Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Design a fantasy RPG rogue character: a lithe elven woman with short silver hair and violet eyes, wearing dark leather armor with buckles and straps, a hooded cloak, twin daggers at her belt, and soft boots. Character concept art, full body front view, neutral A-pose, detailed clothing design, digital painting, dark moody background"
    }]
)

print(response.choices[0].message.content)

With Reference Image

Provide existing art as style or design reference:

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Design a new character in the same art style as this reference. Create a male warrior version: heavy plate armor, greataxe, battle scars, braided red beard. Same visual style, line weight, and color approach as the reference image. Full body concept art."},
              {"type": "image_url", "image_url": {"url": "https://example.com/existing-character-style.png"}}
            ]
          }
    ],
    "stream": false
  }'

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time SSE responses, or "stream": false for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Silhouette Study	black silhouette shapes	readability testing
Color Variations	same design, different palettes	skin/outfit unlocks

Common Pitfalls

• Vague body types — "strong warrior" is ambiguous. Specify build, height, and proportions.
• Style inconsistency — use identical style keywords across all characters for a cohesive cast.
• Overcrowded turnaround sheets — four views maximum per image. More than that reduces quality.
• Hands and fingers are still challenging for AI. For detailed hand poses, plan for touch-up.
• Text on clothing/armor will not render reliably. Describe symbols or patterns instead of words.
