Best Image

Best quality AI image generation (~$0.12-0.20/image). Text-to-image, image-to-image, and image editing via the EvoLink API.

EvoLink Best Image

Generate and edit images via the EvoLink Nano Banana Pro (gemini-3-pro-image-preview) API.

Run

Try Python first (zero dependencies, all platforms):

python3 {baseDir}/scripts/generate.py --prompt "a cute cat" --size "auto"

Options: --size (auto, 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9), --quality (1K, 2K, 4K), --image-urls URL1 URL2 ...

If Python is unavailable:

• Windows: see PowerShell fallback in {baseDir}/references/powershell.md
• Unix/macOS: use the curl fallback in {baseDir}/references/curl_heredoc.md

API key

• EVOLINK_API_KEY env var (required)
• Get key: https://evolink.ai

Triggers

• Chinese: "高质量生图：xxx" / "编辑图片：xxx"
• English: "best image: xxx" / "edit image: xxx"

Treat the text after the colon as prompt, use default size auto and quality 2K, generate immediately.

For image-to-image or editing, the user provides image URLs alongside the prompt.

Notes

• Script prints MEDIA:<path> for OC auto-attach — no extra delivery logic needed.
• Image saved locally (format auto-detected from URL: png/jpg/webp). URL expires ~24h but local file persists.
• --quality 4K incurs additional charges.
• --image-urls accepts up to 10 URLs (each image ≤10MB, formats: jpeg/jpg/png/webp).
