Quick start (curl)

curl -sS 'https://dashscope.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation' \

    "model": "z-image-turbo",
    "input": {
      "messages": [
        {
          "role": "user",
          "content": [{"text": "A calm lake at dawn, a lone angler casting a line, cinematic lighting"}]
        }
      ]
    },
    "parameters": {
      "size": "1024*1024",
      "prompt_extend": false
    }
  }'

Local helper script

python skills/ai/image/alicloud-ai-image-zimage-turbo/scripts/generate_image.py \
  --request '{"prompt":"a fishing scene at dawn, cinematic, realistic","size":"1024*1024"}' \
  --output output/ai-image-zimage-turbo/images/fishing.png \
  --print-response

Size notes

• Total pixels must be between 512*512 and 2048*2048.
• Prefer common sizes like 1024*1024, 1280*720, 1536*864.

Cost note

• prompt_extend=true is billed higher than false. Only enable when you need rewritten prompts.

Output location

• Default output: output/ai-image-zimage-turbo/images/
• Override base dir with OUTPUT_DIR.
