📝

Overview

About this model

Krea 2 Turbo LoRA is an ultra-fast, aesthetic-first image generation model supporting up to 3 custom Low-Rank Adaptation (LoRA) models. It allows creators and developers to generate personalized characters, specific artistic styles, brand assets, and custom visual concepts natively at 1K (~1 megapixel) and 2K (~4 megapixels) resolution in sub-second latency. Supporting both text-to-image and image-to-image workflows with adjustable strength control, Krea 2 Turbo LoRA provides complete creative control. Pair with Krea 2 Turbo, Z-Image Turbo LoRA, or FLUX.1 Dev LoRA for versatile style-adapted production pipelines.

1Character Consistency: Apply custom character LoRA weights to generate recurring subjects across diverse scenes.

2Brand & Art Style Adaptation: Integrate proprietary aesthetic LoRA checkpoints for cohesive marketing campaigns.

3Image-to-Image Customization: Transform existing sketches and photos using reference images combined with custom LoRAs.

4Fast Concept Prototyping: Test and iterate multiple style combinations at 1K and 2K resolutions with low latency.
