In-chat Image Generation

Bring images into your ongoing conversations without switching endpoints. In-chat Image Generation lets you request images directly from the chat/completions endpoint by selecting a base chat model and an image generation model using a simple suffix syntax.

How it works

Base model: Your chat model (e.g., claude-sonnet-4-20250514)
Image model: Your image generator (e.g., flux-pro)
Suffix syntax: baseModel@imageModel

Example suffix: claude-sonnet-4-20250514@flux-pro When you use a suffixed model with chat/completions, the assistant can respond with content that includes generated image(s) inline with its text, keeping the flow immersive for roleplay and storytelling scenarios.

Example request

curl https://api.electronhub.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-4-20250514@flux-pro",
    "messages": [
      {"role": "system", "content": "You are a narrative game master. Embed images when helpful."},
      {"role": "user", "content": "Generate a vivid, cinematic portrait of a cyberpunk detective at night in neon rain."}
    ]
  }'

Notes:

The base chat model drives conversation quality and reasoning.
The image model controls visual style and fidelity.
The response may include image URLs or Markdown image formatting inside the assistant message content.
