Black Forest Labs — FAQ

Frequently asked questions about Black Forest Labs, their FLUX models, licensing, API, and deployment options.

What is Black Forest Labs?

Black Forest Labs (BFL) is a frontier AI research lab focused on building visual infrastructure and generative image models (such as the FLUX family). :contentReference[oaicite:0]{index=0}

What is FLUX.1 Kontext?

FLUX.1 Kontext is a generative “flow matching” model family that supports both image generation and local image editing with in-context prompting (text + image). :contentReference[oaicite:1]{index=1}

How can I access FLUX models?

You can access FLUX models via (1) BFL’s API, (2) downloading open-weights under certain license terms, or (3) using deployment on your own infrastructure. :contentReference[oaicite:2]{index=2}

What is the licensing model?

BFL offers a **Self-Hosted Dev License** for open weights (commercial use allowed under defined terms). Pricing for some models like FLUX.1 Kontext is $999/month up to 100,000 images, with $0.01 per image beyond that. :contentReference[oaicite:3]{index=3}

What can I do with a “dev” license?

With a dev license, you can self-host the model, customize, fine-tune, or deploy it within your own systems, subject to license terms. :contentReference[oaicite:4]{index=4}

Are there any restrictions under the dev license?

Yes — certain commercial or API-resale usages may require a separate commercial license; the license terms specify permitted and prohibited uses. :contentReference[oaicite:5]{index=5}

Will I receive updates to model weights?

Yes — BFL provides model updates under license terms. :contentReference[oaicite:6]{index=6}

How do I integrate via API?

BFL provides simple, production-grade APIs designed to scale. The API is documented in their docs. :contentReference[oaicite:7]{index=7}

Can I use FLUX models commercially?

Yes, under permitted license types (e.g. commercial licenses) and within the constraints of their usage policy. :contentReference[oaicite:8]{index=8}

Which models are available?

Some featured models include FLUX.1 Kontext, FLUX 1.1 Pro Ultra, FLUX 1.1 Pro, and various editing tools (Fill, Canny, Depth). :contentReference[oaicite:9]{index=9}

Can I fine-tune FLUX models?

Yes — BFL supports fine-tuning on certain models via their infrastructure and open-weight offerings. :contentReference[oaicite:10]{index=10}

What is the difference between API and open weights?

API offers hosted access (you send requests), with scalability and ease of use. Open weights allow you to run the model locally or on your own servers with full control and customization. :contentReference[oaicite:11]{index=11}

How fast is FLUX.1 Kontext?

The model offers low latency for both generation and editing, and claims inference speeds up to 8× faster than comparable state-of-the-art models. :contentReference[oaicite:12]{index=12}

What are the known limitations or failure modes?

In heavy multi-turn edits, artifacts may appear. The model may sometimes misinterpret instructions. Also, world knowledge is limited. :contentReference[oaicite:13]{index=13}

How do I try out the models without integration?

You can use the BFL **Playground**, a no-code web interface to test FLUX models interactively. :contentReference[oaicite:14]{index=14}

Are there tools or integrations available?

Yes — for instance, BFL provides ComfyUI nodes that integrate their API into creative workflows. :contentReference[oaicite:15]{index=15}
