Song Generation

Generate complete songs with vocals and full instrumental production 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 an upbeat indie pop song about road trips and summer freedom, female vocal, 120 BPM, with acoustic guitar, claps, and a catchy whistling hook in the chorus"}],
    "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 an upbeat indie pop song about road trips and summer freedom, female vocal, 120 BPM, with acoustic guitar, claps, and a catchy whistling hook in the chorus"}]
)

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

With Reference Image

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": "Generate a song inspired by the mood and atmosphere of this image. Match the emotion, whether it feels melancholy, joyful, or mysterious."},
              {"type": "image_url", "image_url": {"url": "https://example.com/mood-photo.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.

Generate a pop rock song, male vocal, 110 BPM:

[Verse 1]
Walking down these empty streets at dawn
Shadows fading as the night moves on
Every step I take leads back to you
Underneath this sky of fading blue

[Chorus]
We were golden, we were fire
Burning brighter, climbing higher
Now I'm standing in the rain
Chasing echoes of your name

Common Pitfalls

• No vocal direction produces generic voices. Always specify gender, style, and energy level.
• Missing tempo lets the model guess BPM, which may not match your vision. Specify BPM.
• Lyrics without structure markers make it hard for the model to assign verses and choruses correctly.
• Too many genre mixes (e.g., "jazz-metal-country-electronic fusion") dilute the output. Blend 2 genres maximum.
• Ignoring song length may produce clips that are too short or too long for your needs.
