什么是 FLUX 3 Image Klein？
FLUX 3 Image Klein is the first model in Black Forest Labs' FLUX 3 generation, built for speed without sacrificing quality. It combines rapid text-to-image synthesis with multi-reference image editing — attach up to 10 reference images and direct every edit in plain language, at resolutions up to 4K.
Lightning-Fast Generation
Most images finish in 10-20 seconds — among the fastest production image models available, perfect for iterating on ideas without breaking your creative flow.
Native 4K Resolution
Go up to 4096x4096 pixels for print-ready posters, banners and product shots. Higher resolutions cost more credits but deliver publication-grade sharpness.
10-Reference Image Editing
Upload up to 10 reference images and edit them with plain-language instructions — reference images are free and only affect generation time, never quality.
Budget-Friendly Pricing
Starting at just 2 credits per 1K image, FLUX 3 Image Klein is the most affordable premium model on our platform — ideal for high-volume creation.

Rapid Text-to-Image
FLUX 3 Image Klein turns prompts into polished visuals in 10-20 seconds. Prompt enhancement rewrites terse ideas into rich descriptions automatically, boosting quality with zero extra effort.
Up to 4K Output
Choose 1K for quick drafts, 2K for social media, or 4K for print. The width/height parameters accept any aspect ratio between 1:2.5 and 2.5:1.
Multi-Reference Editing
Edit with words, keep what matters.
10 Reference Images
Combine up to 10 references — products, characters, styles — and direct edits by order: "replace the background in image 2". References are processed free.
Literal Instruction Mode
Turn off prompt enhancement when you need exact compliance — fixed compositions, precise text edits, or "keep X unchanged" instructions are followed literally.
Creator Economics
Premium quality without premium pricing.
2 Credits Per Image
1K images cost just 2 credits — a fraction of comparable premium models. Batch-generate with up to 4 images per run to explore variations affordably.
Reproducible Seeds
Lock a seed to reproduce results or generate variations: image i uses seed + i, so batches stay coherent while exploring directions.
Flexible Output
Right format, first time.
10 Aspect Ratios
From 9:21 stories to 21:9 cinematic banners plus auto mode — every ratio the model supports is one click away in the generator.
PNG, JPEG & WebP
Export in the format your pipeline needs. WebP keeps file sizes small for the web; PNG preserves maximum quality for editing.
