FLUX.1.1 Pro Model Suite by Black Forest Labs
Overview
FLUX.1.1 Pro is a 12-billion parameter hybrid transformer model developed by Black Forest Labs, released in October 2024. It builds on the rectified flow foundation of FLUX.1 and introduces a multimodal hybrid architecture with parallel diffusion. FLUX.1.1 Pro offers dramatically faster image generation—up to 6x faster than FLUX.1 Pro—while maintaining or even improving image fidelity and prompt adherence.
Features
- Up to 6x faster generation compared to FLUX.1 Pro
- Hybrid architecture: multimodal transformer + diffusion
- API-based access with support for customization
- Optimized for scaling from individual creators to enterprises
- Improved prompt understanding and detail generation
Use Cases
- Professional-grade content and image generation
- Marketing, media, and advertising visuals
- High-fidelity illustrations and conceptual design
- Scalable generation pipelines and creative tools
- Rapid prototyping with production-level quality
Limitations
- Optimal performance requires modern GPU hardware
- May consume more resources than smaller or basic models
