About

Generate 4MP photoreal images from a prompt and edit them in the web playground or via API. Designers and product teams use it for concept art, UI mockups, and product shots, with sub-second turns on the FLUX.2 [klein] model and optional fine-tuning for brand consistency. Multi-reference control keeps subjects and style aligned across a batch.

Editor's Take

Worth trying if you need fast, publication‑quality 4MP images and consistent multi‑reference control; best suited for designers and teams who want high‑DPI outputs and the option to run or fine‑tune the model locally.

Key Features

Type a prompt or add reference images → get 4MP photoreal outputs ready for high-DPI use
Provide multiple reference images → maintain consistent subject and style via multi-reference control
Choose FLUX.2 [klein] on capable hardware → sub-second generations for rapid iteration
Run the model locally → keep data on your machine and fine-tune with your own examples
Call the REST API with prompt and refs → metered billing at $0.05 per megapixel across inputs and outputs

Use Cases

A UI/UX designer rapidly prototyping 10+ screen concepts for a stakeholder review the same afternoon
A marketing team generating consistent product shots across colors and angles for an e-commerce launch
A game artist iterating character concepts with reference-controlled style for a pitch deck

Try It Like This

1
Generate a publication-ready product shot
Open the web playground or call the REST API → provide a short prompt plus 2–3 reference photos of the product and set output to 4MP → receive photorealistic images suitable for high‑DPI use (first results in sub-second on FLUX.2 [klein] on capable hardware; otherwise expect a few seconds).
2
Create a batch of UI mockups
Access Flux.2 through the web app → write a series of prompts describing different screen layouts and include a single style reference image to keep visuals consistent → generate multiple 4MP variations for stakeholder review and iterate quickly using the playground.
3
Iterate character concepts with consistent style
Upload several reference images showing the character and desired art direction → prompt for pose/color/angle variations and enable multi-reference control to lock subject/style → produce a consistent set of high-resolution concepts for a pitch deck.
4
Fine-tune for brand consistency locally
Set up the local runtime and provide your example images for fine-tuning → run the optional fine-tune process to bias the model toward your brand’s assets → generate on-device 4MP images that match brand guidelines while keeping data local.
5
Automate product image generation via API
Integrate the REST API into your content pipeline and send prompts with reference images → configure outputs at 4MP and track cost at $0.05 per megapixel → receive images programmatically and pull them into your e‑commerce CMS for batch publishing.

Pros & Cons

Pros

Outputs native 4MP photoreal images suitable for high‑DPI use, so results are ready for print and detailed product shots.
Multi-reference control lets you keep subjects and style aligned across a batch by supplying multiple reference images.
Offers FLUX.2 [klein] for sub-second generations on capable hardware, plus options to run locally and fine-tune on your own examples.

Cons

Usage is metered at $0.05 per megapixel across inputs and outputs, which can add up for large batches of 4MP images.
Sub-second generation speed depends on capable local or hosted hardware; slower hardware will increase wait times.
Smaller ecosystem/community compared with established tools (e.g., Midjourney), so fewer ready-made community prompts and assets are available.

Getting Started

1 Open the Playground at playground.bfl.ai or access the FLUX.2 API from bfl.ai
2 Select a FLUX.2 model (e.g., klein) and enter a prompt; optionally upload reference images
3 Generate your first 4MP image in seconds and refine with additional prompts or references
