Create and edit images with one command

The /image command is Krater’s all-in-one visual studio. Send a text prompt to generate a fresh image, or attach images to edit, restyle, or combine existing ones — /image switches into edit mode automatically when an image is attached.

How to use

Generate from text:

/image A serene Japanese garden at sunset with cherry blossoms

The /image command with model and aspect-ratio options

Edit an existing photo: click the + button next to the chat input, attach an image, then describe the change:

/image Make the sky a dramatic sunset and remove the cars

When one or more images are attached, /image switches to image-to-image mode automatically — no separate command needed. The picker then lists only models that support editing, and models that allow it accept multiple reference images for composite scenes, character consistency, or style transfer.

Available models

Krater always carries the latest image models. Open the options panel to switch model, aspect ratio, and count:

Model	Credits	Best for
Flux 2	3	Default pick — photorealistic workhorse; Pro, Max, Flex, Flash, Turbo and Klein rungs up to 18
Nano Banana	10	Google’s all-rounder for generation and editing; Pro rung 38
Nano Banana 2 / 2 Lite	20 / 11	Gemini 3.1 Flash generation with a 1K–4K resolution control
GPT Image 2	from 14	OpenAI’s latest — fine typography, strong instruction-following, exact sizes up to 4K, Low/Medium/High quality
Grok Imagine	15	xAI’s expressive model with the widest choice of aspect ratios
Recraft V4.1	9	Text in images, logos, and vector styles (Pro 53)
Ideogram V4	from 3	Typography and text-heavy designs; Turbo, Balanced, and Quality speeds

Credits shown are per image at the default size. The live estimate in the options panel always reflects the exact model, size, quality, and count you picked before you send. Billing starts at 3 credits minimum.

Aspect ratios

Ratios depend on the model. Most offer:

1:1 — social posts, avatars, icons (with an HD variant for +1 credit)
16:9 — landscape (YouTube, presentations, banners)
9:16 — portrait (Stories, Reels, TikTok)
4:3 — standard photo
3:4 — portrait photo

Several models go further: Nano Banana adds 3:2, 2:3, and 21:9; Nano Banana 2 adds Auto, 5:4, and 4:5; Krea and Kling include 3:2, 2:3, and 21:9 (plus cinematic 2.35:1 on Krea); Grok Imagine covers phone-native ratios like 9:20 and 9:19.5. Resolution and quality controls appear where the model supports them — Nano Banana 2 and Kling O3 offer 1K–4K, GPT Image 2 offers exact pixel sizes up to 3840×2160 plus Low/Medium/High quality.

Count

Generate 1 to 4 variations per prompt. Each image is billed separately, and some models (Flux 2 Pro/Max/Flex, Recraft, Krea 2) render one image at a time.

Prompting tips

Be specific and descriptive:

Weak: “A cat”
Strong: “A fluffy orange tabby cat sleeping on a velvet couch, soft window light, photorealistic”

Include style keywords:

Photorealistic, oil painting, watercolor, anime, 3D render, pencil sketch

Mention lighting and mood:

Golden hour, dramatic shadows, neon glow, soft diffused light

For edits, be surgical:

Weak: “Make it nicer”
Strong: “Remove the trash can on the left and brighten the foreground”
Strong: “Convert to a watercolor painting, keep the same composition”

Tips for great results

Save reusable prompt templates under Additions → Prompts so you can re-run them across projects; finished images can be saved to Keep
Combine multiple reference images on supported models — up to 10 on Seedream 5.0 and Kling O3 — to lock character identity, palette, or style
Use higher-quality settings and 4K resolutions for hero shots; use Flux 2 or Z-Image Turbo (3 credits) for quick iterations
Want more pixels on a finished image? Upscale it — or animate it
