FLUX.2 [pro] - Starrise AI

FLUX.2 [pro] is an advanced text-to-image model from Black Forest Labs, available through Starrise AI. It supports up to 4MP resolution and multi-reference-image consistency. The API uses synchronous calls — it directly returns Base64-encoded image data.

Key Capabilities

Text-to-image — Generate images from text descriptions
High resolution — supports up to 4MP output resolution
Reproducible — Use seed for deterministic generation
Format options — supports jpeg or png output

Quick Example

curl https://ai.alad.com/v1/images/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "flux-2-pro",
    "prompt": "A cute baby polar bear",
    "size": "1024x1024"
  }'

import requests

response = requests.post(
    "https://ai.alad.com/v1/images/generations",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "model": "flux-2-pro",
        "prompt": "A cute baby polar bear",
        "size": "1024x1024"
    }
)

result = response.json()
# result["data"][0]["b64_json"] contains the Base64-encoded image
