PoYo GPT Image 2 Generation and Editing

Use this skill for GPT Image 2 jobs on PoYo. It covers text-to-image generation, reference-image-guided generation, and multi-image editing payloads for gpt-image-2 and gpt-image-2-edit.

Use When

• The user explicitly mentions GPT Image 2, gpt-image-2, or gpt-image-2-edit.
• The task is text-to-image, image-to-image, or editing one or more supplied images.
• The workflow needs broader aspect-ratio support, custom pixel size, or 1K / 2K / 4K resolution control.

Model Selection

• gpt-image-2: text-to-image generation and optional reference-image-guided generation.
• gpt-image-2-edit: editing based on one or more reference images and a text instruction; requires image_urls.

Key Inputs

• prompt is required inside input and is limited to 4000 characters.
• image_urls is required for gpt-image-2-edit and supports multiple input images.
• Each request returns a single image.
• size supports auto, 1:1, 2:3, 3:2, 4:3, 3:4, 4:5, 5:4, 16:9, 9:16, 21:9, or custom WIDTHxHEIGHT.
• resolution supports 1K, 2K, and 4K.
• Custom WIDTHxHEIGHT sizes require resolution to be 2K or 4K.
• auto size or omitted size always uses 1K resolution.

Execution

• Read references/api.md for endpoint details, model ids, key fields, example payloads, resolution notes, and polling notes.
• Use scripts/submit_gpt_image_2.sh to submit a raw JSON payload from the shell.
• If the user only needs a curl example, adapt one from references/api.md instead of rewriting from scratch.
• After submission, report the task_id clearly so follow-up polling is easy.

Output Expectations

When helping with this model family, include:

• chosen model id
• whether the request is text-to-image, reference-guided generation, or editing
• final payload or a concise parameter summary
• selected size and resolution
• whether reference images are involved
• returned task_id if a request was actually submitted
• next step: poll status or wait for webhook
