Model-aware thumbnail generation

Make the model settings visible, not mysterious

The AI image generator page now ties GPT Image 2, GPT-4o Image, aspect ratios, reference images, and credit cost to concrete thumbnail examples.

GPT Image 2 and GPT-4o Image as configurable thumbnail models

Admins can choose the default KIE model and hide models that are not enabled. This page explains that model choice with a product screenshot instead of a vague AI claim.

Provider options are driven by configured API keys, so disabled providers are not shown publicly.
Aspect ratio, quality, resolution, and output format appear only when the selected model supports them.
Credit cost is configured in settings and shown before a user starts generation.

Reference-image thumbnails for creators and products

When users upload a face or product, the page should show what that workflow is for: recognizable people, consistent brand anchors, and a thumbnail history that can be compared later.

The image supports the image-to-thumbnail keyword with an actual creator use case.
Copy explains what happens before generation without triggering any image API call.
The CTA routes users back to the maker with a specific style intent.

AI image generation tuned for thumbnail work

This page keeps the generator focused on creator tasks: bold thumbnail concepts, reference-image consistency, and model settings that admins can change without code.

Text-to-thumbnail

Turn a video idea into a thumbnail concept with YouTube-friendly composition and readable hook text.

Image-to-thumbnail

Upload a face, product, or scene reference so generated thumbnails keep recognizable visual anchors.

Configurable KIE models

Use GPT Image 2, GPT-4o Image, Nano Banana, or Seedream models based on the Admin model list.

Aspect-ratio controls

Expose only the ratios a model supports, including 16:9 for YouTube thumbnails and vertical formats for Shorts.

Quality and resolution

Model-specific quality, resolution, and output-format fields appear only when the selected model supports them.

No hidden providers

The dropdown is built from configured API keys, so disabled providers stay out of the public UI.

How it works

Pick a model, shape the prompt, keep control

A clearer page helps users understand what changes before they spend credits.

Step 1

Select the configured provider

Admin settings decide the provider list. If KIE is the only active provider, users only see KIE.

Step 2

Choose a model and ratio

Model options are mapped to KIE request fields, including GPT Image 2's input_urls for image-to-image.

Step 3

Review before generating

The page shows cost, credits, prompt length, and upload state before creating an AI task.
