What is FLUX?
FLUX is Black Forest Labs' image generation and editing model family. The current generation, FLUX.2, released November 2025, combines text-to-image synthesis and multi-reference editing in a single model — generating photorealistic images at up to 4 megapixels with clean typography, up to 10 reference images, and production-grade editing tools.
How much does FLUX cost in Phygital+?
Usage is credit-based and included in every Phygital+ plan — from the free plan up to Enterprise. The exact credit cost per generation is shown live in the node before you run it, so you can start for free and scale as you go. This is separate from Black Forest Labs' own API pricing of roughly $0.03 per megapixel.
Can I use FLUX outputs commercially?
Outputs created on any paid plan (Starter and up) come with commercial-use rights. Licensing on the vendor side is more layered: [pro] and [flex] are hosted commercial endpoints, [dev] requires a commercial license from BFL for commercial use, and [klein] 4B is Apache 2.0 with no license fee. Check the model card for any provider-specific limits.
Who makes FLUX?
FLUX is made by Black Forest Labs, a German-American AI company headquartered in Freiburg im Breisgau, founded in 2024 by Robin Rombach, Andreas Blattmann, Patrick Esser, and Dominik Lorenz — the original core creators of latent diffusion and Stable Diffusion. The company raised a $300M Series B at a $3.25B valuation in December 2025.
What are the FLUX.2 variants?
Four tiers. [pro] is the production API tier with state-of-the-art quality. [flex] gives developers control over steps and guidance scale, trading quality against latency. [dev] is a 32B open-weight model on Hugging Face. [klein] is a compact distilled variant — 4B and 9B — for sub-second generation on consumer hardware, with the 4B under Apache 2.0.
What resolution does FLUX support?
FLUX.2 generates and edits at up to 4 megapixels — roughly 2048×2048 — while preserving detail and coherence. Costs scale linearly with megapixels on the vendor API, so a 2048×1024 banner costs about twice a 1024×1024 image.
Can FLUX render text in images?
Yes — clean typography is one of its strengths, with precise rendering even at small sizes and reported ~92% accuracy on complex layouts, infographics, and UI text. For long-form typography, models built specifically for text still lead.
How many reference images can FLUX use?
Up to 10 at once, with character, layout, and style adherence across them. Reference images count toward the megapixel total on the vendor API, so multi-reference calls cost more.
Is there an API for FLUX?
Yes. Black Forest Labs offers a production API, and FLUX models are also available via partners including FAL, Replicate, Together AI, and Cloudflare. In Phygital+, you can run FLUX as a node on any plan, and API and integration support is available on the Enterprise plan.
Why use FLUX inside Phygital+?
Running FLUX in Phygital+ means no local GPU, no separate signup, and no credit balance for one model — the 32B [dev] model alone needs roughly 90GB VRAM to run locally. In Phygital+ it sits on the same canvas as 30+ other AI tools, chaining generation, editing, upscaling, and video into one repeatable workflow.
