What This Skill Does

Generates images from text prompts using EvoLink's z-image-turbo API at approximately $0.0036 per image. Supports nine aspect ratios and runs via Python, PowerShell, or curl. Images are saved locally; the download URL expires after 24 hours but the local file persists.

At ~$0.0036 per image, it costs a fraction of mainstream AI image APIs like DALL-E or Stable Diffusion hosted services.

When to use it

  • Generating a visual concept without a paid Midjourney or DALL-E subscription
  • Creating illustration drafts for blog posts at minimal cost
  • Batch producing reference images for a design mood board
  • Quickly visualizing a product idea from a text description
  • Generating social media images in specific aspect ratios like 9:16 or 16:9

Example Workflow

Here's how your AI assistant might use this skill in practice.

AGENT
  1. 1Extracts the prompt from the trigger phrase after the colon
  2. 2Sets the aspect ratio to the default 1:1
  3. 3Calls the EvoLink z-image-turbo API with the prompt and size parameters
  4. 4Downloads the returned image and saves it locally
  5. 5Outputs MEDIA:<path> so the file is auto-attached to the conversation
OUTPUT

Local image file of a golden retriever puppy in a sunflower field, attached to the conversation
