Flux
Overview
Flux is a family of image generation models from Black Forest Labs (BFL). The 2026 flagship is FLUX.2, which extends the FLUX.1 architecture with multi-reference conditioning across up to 10 reference images, coherent 4-megapixel generation and editing, and unified editing inside a single model. On both photorealism and prompt following it sits at the frontier alongside Midjourney and Google's Nano Banana Pro.
Key Features
Multi-reference conditioning
FLUX.2 can pull in up to 10 reference images and preserve the same character, layout and style across generations — a meaningful advantage for comics, ad campaigns and other jobs that need consistency.
Open-weight + commercial endpoints
FLUX.2 ships in multiple variants (Pro / Flex / Dev / Klein 4B). Pro and Flex are proprietary hosted endpoints; Dev is an open-weight download that requires a commercial license from BFL for commercial use.
High-resolution and improved text
4MP generation and editing, meaningfully better text rendering and stronger fine detail make FLUX.2 credible for commercial photo work.
Plans & Pricing
| Delivery | Price | Notes |
|---|---|---|
| BFL API | 1 credit = $0.01 | Per-image |
| FLUX.2 [Pro] | ~$0.03 per MP | 1024×1024 ≈ $0.030 |

Flux has no first-party consumer subscription — you consume it pay-as-you-go via API or through hosts like Together.ai, Replicate or OpenRouter.
Typical Use Cases
- Photoreal ad visuals and product shots
- Comics, picture books and storyboards that need character consistency
- Product background swap and variant generation
- Advanced pipelines combining Dev weights + LoRAs in ComfyUI
Strengths
- Top-tier 2026 photorealism and prompt adherence
- Up to 10 reference images for consistency
- Open-weight Dev variant enables local use
- Much improved text rendering generation over generation
Weaknesses
- No polished consumer UI — API / third-party surfaces only
- Commercial use of the Dev model requires a separate BFL license
- High-resolution generation can get expensive
