Flux 3
Flux 3 - Multimodal AI Foundation Model
Introduction:
Flux 3 is Black Forest Labs' multimodal AI model that unifies image, video, and audio generation via Self-Flow architecture.
Flux 3 Product Information
What is Flux 3 ?
FLUX 3 is a multimodal foundation model developed by Black Forest Labs that establishes a unified architecture for generative visual intelligence. Rather than operating separate specialized engines for text, visuals, and sound, FLUX 3 jointly learns from images, videos, and audio using a proprietary Self-Flow approach designed to align generative synthesis with multimodal understanding. The model supports video generation with synchronized audio, photorealistic image creation, and multi-resolution outputs up to 4K. It is structured to serve researchers, creators, and enterprise software developers through cloud interfaces, developer APIs, and open-weight community tiers.

FAQ from Flux 3
What is Flux 3?
- Flux 3 is a multimodal AI foundation model developed by Black Forest Labs that jointly learns from images, videos, and audio within a unified architecture built on the Self-Flow approach.
What is the Self-Flow approach in Flux 3?
- The Self-Flow approach aligns generation and comprehension across modalities into a unified training framework, allowing the model to simultaneously interpret and generate visual and audio content.
How does Flux 3 differ from earlier Flux models?
- While earlier models like Flux 1 focused primarily on static text-to-image generation, Flux 3 integrates image, video, and audio synthesis natively within a single foundation model architecture.
What model variants are available for Flux 3?
- Flux 3 is architected for multiple deployment environments, including cloud API endpoints, production-grade closed models, and open-weight developer tiers (such as Flux 3 Dev and Klein) for self-hosting and research.
How is Flux 3 priced?
- Platforms providing Flux 3 access typically offer a freemium tier with test credits, recurring monthly plans, one-time credit top-ups, and metered API billing for developers.
