image-creation

Generate images via Seedream.

Required Env

• ARK_API_KEY (required)
• SEEDREAM_TEXT_ENDPOINT_ID (optional; fallback: SEEDREAM_TEXT_MODEL -> built-in default model)
• SEEDREAM_I2I_ENDPOINT_ID (required for refine)

Constraints

• Backend minimum pixels: 1920*1920. Smaller inputs (for example 1024x1024) are auto-upscaled.
• success=true only when the output file is actually written and non-empty.
• Backend response must contain b64_json or url; otherwise the call fails.
• Default output path is /tmp unless output is provided.
• watermark defaults to false (no "AI generated" watermark). Set to true only when you explicitly need watermark.
