AI Sprite Generator

Generate 2D sprite sheets and animated character sprites 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": "Generate a pixel art sprite sheet showing a knight character walk cycle. 8 frames in a horizontal strip, side-view facing right, 32x32 pixels per frame. The knight wears silver armor with a blue cape and carries a sword. Classic 16-bit SNES style, transparent background, evenly spaced frames."
      }
    ],
    "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": "Generate a pixel art sprite sheet showing a knight character walk cycle. 8 frames in a horizontal strip, side-view facing right, 32x32 pixels per frame. The knight wears silver armor with a blue cape and carries a sword. Classic 16-bit SNES style, transparent background, evenly spaced frames."
    }]
)

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

With Reference Image

Match the style of existing sprites:

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": "Create a new enemy sprite sheet matching the art style of this reference. Design a skeleton archer: idle pose, drawing bow, releasing arrow, and taking damage. 4 frames horizontal strip, same pixel size and palette as the reference."},
              {"type": "image_url", "image_url": {"url": "https://example.com/existing-sprites.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.

Sprite Sheet Types

Type	Frames	Description
Walk Cycle	4-8	character locomotion loop
Run Cycle	6-8	faster movement loop
Idle	2-4	breathing or subtle motion loop
Attack	4-6	swing, slash, or projectile
Jump	3-5	crouch, rise, apex, fall, land
Death	4-6	hit reaction and collapse
Effect	4-8	explosion, magic spell, smoke
Direction Set	4-8	same pose facing N, S, E, W

Prompt Engineering Tips

Prompt Structure

"Generate a [art style] sprite sheet showing [character] [animation type]." + [frame count] + [layout] + [pixel size] + [visual details] + [background]

Layout Specifications

horizontal strip — all frames in a single row
vertical strip — all frames in a single column
grid layout (4x4) — rows and columns for multiple animations
single sprite — one frame only (static asset)

Pixel Art Resolution Keywords

8-bit NES style (8x8, 16x16 pixels)
16-bit SNES style (16x16, 32x32 pixels)
32-bit style (32x32, 64x64 pixels)
high-res pixel art (64x64, 128x128 pixels)

Common Pitfalls

• Inconsistent character across frames — the biggest challenge. Describe the character identically and reference earlier frames if using conversation history.
• Frame count too high — more than 8 frames in one image reduces per-frame quality. Keep it to 4-8.
• Missing size specification — always state pixel dimensions per frame.
• No layout description — without "horizontal strip" or "grid", frames may be randomly arranged.
• Mixed perspectives — do not mix side-view and top-down in one sheet. Be explicit about perspective.
