Flux review: FLUX image models from Black Forest Labs

Flux Review: Features, Pricing and Who It Suits Best

Flux is a family of image generation models from Black Forest Labs, the company founded in 2024 by former Stability AI researchers behind Stable Diffusion. There is no single Flux app with a monthly plan. You pay per image through the official API, or you run open-weight models on your own hardware. FLUX.1 [dev] is a 12-billion-parameter model released on August 1, 2024. The current lineup runs from FLUX.1 through FLUX.2 to FLUX 3, which arrived on October 1, 2026 with image and video models. This review covers the models, the pay-as-you-go pricing, the open-weight options and who each tier suits.

What Flux Is

Flux is a model family, not a design app. Black Forest Labs sells access through its hosted API and Playground, and also publishes downloadable model weights for some versions. The models generate images from text prompts and edit existing images from text instructions. FLUX.1 Kontext is the dedicated editing branch, built for repeated edits with strong character consistency. FLUX 3 added video generation, priced per second of output. Developers call the models through an API. Designers usually reach them through third-party apps, such as Recraft, which license Flux on paid plans. There is no official Flux subscription, no seat fee and no free tier on the hosted API. You pay only for what you generate.

FLUX.1 prices are flat per image on the official API, where one credit equals $0.01. FLUX.2 prices scale with resolution. FLUX 3 Image is priced per image by resolution tier. The official pricing calculator lists $0.048 per image at the 1K tier. An independent pricing guide lists FLUX 3 Image from $0.041 at 768 by 768 pixels up to $0.607 at 4K. FLUX 3 video starts at $0.17 per second for HD text-to-video. Failed generations and outputs withheld by moderation are not charged, according to the official pricing page.

Flux Pricing: Pay As You Go

The official pricing page states the model clearly. There are no subscriptions and no seat fees. You pay for what you generate. Enterprise buyers can negotiate custom pricing, volume discounts, SLA guarantees and dedicated support. For small teams, the per-image math is simple. A hundred FLUX1.1 [pro] images cost $4. A hundred Kontext [pro] edits cost $4. A hundred FLUX 3 images at the 1K tier cost $4.80. FLUX.2 [pro] at $0.03 per megapixel costs about $0.03 for a 1-megapixel image and rises with resolution. Use the official pricing calculator for an exact quote at your target size, since FLUX.2 and FLUX 3 prices depend on resolution. Flux is also available through marketplaces such as Replicate and fal.ai, where prices differ slightly from the official API. Compare the marketplace rate against the official rate before you build on one.

Open Weights and Licensing

Flux stands out because some models are open-weight. FLUX.1 [dev] weights are downloadable and free to run on your own infrastructure, under a non-commercial license. FLUX.1 [schnell] is released under the Apache 2.0 license. Black Forest Labs also sells open-weights licenses for commercial use. The Builder tier covers FLUX 3 Image Klein and FLUX.2 [klein], with 10,000 images a month, 1 domain and 10 licensed users. Platform covers up to 100,000 images a month. Professional covers agencies and service providers. Enterprise covers all models, custom volumes and permissive commercial use. All tiers include fine-tuning and LoRA rights. This matters for teams that want to run models locally, fine-tune on their own data, or avoid per-image API bills at scale. Check the license for the exact model you plan to use. The dev license does not allow commercial use, while schnell does.

Strengths and Limits

Flux is known for strong prompt adherence and realistic images. It handles text inside images better than most rivals, which matters for posters, labels and product shots. Kontext keeps a character or object consistent across repeated edits, a real advantage for storyboards and brand work. The open-weight models give developers a self-hosted path that closed rivals do not offer. The limits are practical. There is no official consumer app, so non-developers reach Flux through third-party tools. There is no free tier on the hosted API. The model lineup changes fast, and prices differ between the official API and marketplaces. FLUX.1 is now described by Black Forest Labs as a previous generation, though its hosted versions remain available. New buyers should start with FLUX.2 or FLUX 3 unless they have a reason to use the older models.

Bottom Line

Flux suits developers and teams who want strong image quality with per-image pricing and no subscription. It suits anyone who needs consistent character editing through Kontext, or a self-hosted model through the open weights. It suits casual users less well, since there is no official app or free tier. Start with FLUX.2 [pro] or FLUX 3 Image on the official API for the best current quality. Use FLUX.1 [dev] locally if you want to test the technology without API bills. Confirm the price on the official calculator before you budget, since resolution changes the cost.
