Poster Design

Design striking event, movie, and promotional posters 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 vintage-style jazz concert poster. A saxophone player silhouette against a smoky spotlight, art deco geometric borders, warm amber and deep brown tones, aged paper texture, classic 1940s jazz club aesthetic, portrait orientation."
      }
    ],
    "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 vintage-style jazz concert poster. A saxophone player silhouette against a smoky spotlight, art deco geometric borders, warm amber and deep brown tones, aged paper texture, classic 1940s jazz club aesthetic, portrait orientation."
    }]
)

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

With Reference Image

Supply a style reference or previous poster from the same series:

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 concert poster in the same visual style as this reference. Same color palette and layout structure, but change the subject to a guitarist with stage lights, keep the vintage screenprint texture."},
              {"type": "image_url", "image_url": {"url": "https://example.com/previous-poster.jpg"}}
            ]
          }
    ],
    "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.

Prompt Engineering Tips

Keywords That Work

poster design, bold composition, dramatic focal point, high contrast,
striking visual hierarchy, strong silhouette, cinematic framing,
screenprint style, large central image, border framing, portrait orientation

Keywords to Avoid

detailed small text — AI text rendering is unreliable
too many subjects — posters need a single focal point
landscape orientation — most posters are portrait
realistic photograph — illustrated styles work better for posters

Prompt Structure

[style] poster for [event type], [subject/scene], [artistic technique], [color palette], [mood], portrait orientation

  }'

Design Principles for Posters

• One dominant element — the poster should communicate its message from across the room
• High contrast — must be readable from a distance and at small sizes online
• Visual hierarchy — the eye should flow naturally from the main image to supporting elements
• Leave text zones — reserve the top 20% and bottom 30% for title and event details
• Print considerations — design at 300 DPI for physical printing (standard sizes: 18x24in, 24x36in, A2, A3)

Workflow

# Step 1: Generate the poster concept
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": "Minimalist film noir poster. A detective silhouette standing under a streetlamp in rain, long shadow stretching forward, black and white with one accent of red from a neon sign reflection, portrait orientation."
      }
    ],
    "stream": false
  }'

# Step 2: Refine the composition
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": "Minimalist film noir poster. A detective silhouette standing under a streetlamp in rain, long shadow stretching forward, black and white with one accent of red from a neon sign reflection, portrait orientation."
      },
      {
        "role": "assistant",
        "content": "..."
      },
      {
        "role": "user",
        "content": "Add rain streaks catching the light, make the shadow more prominent, and add a faint city skyline in the background fog. Keep the minimalist black and white with red accent."
      }
    ],
    "stream": false
  }'
