Selection guide

Use these decision points when choosing a model.

1
Choose the frame and resolution for prompt-only generation

Choose the frame and resolution for prompt-only generation — For a prompt-only task, first choose the delivery ratio from seven aspect ratios, then select 1K or 2K for the required pixels. The two tiers currently cost 5 and 7 credits.

2
Give every uploaded image a role

Give every uploaded image a role — Upload only images you are entitled to use and modify, and explain each image's role. Before public, commercial, or important use, review rights, facts, text, color, people, and brand elements; the input limit does not guarantee any of these results.

3

Use cases

Generate an image in a chosen frame

Select the aspect ratio for a page, social post, or presentation, then describe the subject, environment, composition, lighting, color, and anything the output should avoid.

Request changes to one existing image

Upload one image you have permission to use and specify what to preserve, replace, add, or remove. Review the output for subject, text, and color accuracy.

Combine several reference images

Use separate images for the subject, background, material, or layout, but explain the relationship in the prompt and check that the result has not merged or omitted elements incorrectly.

Prompt tips

State the task before the visual conditions

Production-focused models such as FLUX benefit from structured prompts. Clearly defining the subject, scene, camera, material, and constraints can reduce rework.

Increase resolution only when it serves the task

1K and 2K currently cost 5 and 7 credits. You can inspect composition and instruction handling at the lower tier before testing 2K; a higher tier does not mean every detail will improve.

Number each reference and define its purpose

For multiple inputs, identify image 1, image 2, and so on as the source for a subject, background, color, or material. Conflicting references may force the model to choose, so review the result manually.

Why choose it

Runtime / Capabilities — Text-to-image, image-to-image
Upload limit — Editing accepts up to eight images with clear format, size, and count limits.
Aspect ratio / Resolution — Seven fixed aspect ratios and 1K/2K apply to both generation and editing.
Credit cost — The 5/7-credit resolution cost is visible before submission.

What to know first

Flux 2 Pro / Integration — The current interface does not offer `aspect_ratio=auto`, 4K, or an output-format choice.
Flux 2 Flex — For complex tasks that need a higher tolerance for failed attempts, it may still be worth comparing Flex.
Runtime / Category — It may not be the first choice for highly stylized or burst-of-creativity work.
