gpt-image-2（GPT Image 2 图像生成）

GPT-Image-2

Generate images through Frevana's AI Factory OpenAI backend with a fixed contract:

• provider: openai
• model: gpt-image-2

This skill returns the validated API response JSON unchanged. Treat data[0].image_url as the primary image URL.

What This Skill Needs

• user-provided prompt or contents
• optional OpenAI image options: n, size, quality, background, output_format, output_compression
• FREVANA_TOKEN in the environment, or an explicit --token override for the current run
• curl
• bash
• python3

Execution Order

1. Confirm the user provided the image prompt.
2. Do not ask for or pass through provider or model; this skill fixes them.
3. Prefer the script over ad hoc curl commands.
4. Let the script read FREVANA_TOKEN first.
5. In non-interactive runs, fail fast if the token is missing and tell the user to set FREVANA_TOKEN or pass --token.
6. Return the raw API response JSON, or the first image URL when the user only wants the hosted asset.
7. Save the JSON with --output when useful.

Allowed Options

• --n: 1-10
• --size: auto, 1024x1024, 1536x1024, 1024x1536, 256x256, 512x512, 1792x1024, 1024x1792
• --quality: standard, hd, low, medium, high, auto
• --background: transparent, opaque, auto
• --output-format: png, jpeg, webp
• --output-compression: 1-100

  --prompt "A cinematic product photo of a matte black espresso machine on travertine" \
  --size 1536x1024 \
  --quality high \
  --background opaque \
  --output-format png \
  --output ./out/gpt-image-2-result.json

Notes

• Do not pass --provider or --model; the wrapper rejects overrides.
• Do not rewrite, proxy, or transform the returned Frevana image URLs unless the user asks for that.
