# FLUX 2 Pro

FLUX 2 Pro is Black Forest Labs' FLUX.2 [pro], a production-grade model for image generation and multi-reference editing, launched in November 2025. It is known for photorealism and for matching brand colours given as hex codes. In Sloosh it makes 1K images from a prompt and up to 8 reference images, with a seed to repeat results.

## Best for

- Photoreal product scenes in exact brand colours. BFL says FLUX.2 can "specify brand colors via hex codes with precision matching" ([BFL](https://docs.bfl.ai/flux_2/flux2_overview)).
- Composites from separate references (product, setting, style). BFL's [pro] API takes up to 8 references at 1MP output ([BFL prompting guide](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- Repeatable variations: Sloosh exposes a seed for FLUX 2 Pro, so you can rerun a result and change one thing.
- Product-on-surface ads: the Product Reimagined Fifty Ways Space ([sloosh.ai/spaces/product-reimagined-fifty-ways](https://sloosh.ai/spaces/product-reimagined-fifty-ways)) fits this job.

## How to use FLUX 2 Pro in Sloosh

1. Open [Image Studio with FLUX 2 Pro selected](https://sloosh.ai/studio/image?image-model=flux-2-pro), or pick FLUX 2 Pro in the model chip.
2. Add up to 8 references. Put the base image first.
3. Write the prompt, most important element first, with each hex colour tied to an object.
4. Pick an aspect ratio. Set a seed if you want to repeat a result.
5. Check the cost on the Generate button, then generate.

## FLUX 2 Pro prompting tips

- FLUX.2 weights earlier words more: order the prompt main subject, key action, style, context, then secondary details ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- 30 to 80 words suits most projects; go past 80 only for complex scenes ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- Tie each hex code to a specific object, for example "sofa in hex #1B6B6F"; "use #FF0000 somewhere" gives inconsistent results ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- No negative prompts: say "sharp focus throughout" rather than "no blur" ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- Name the camera, lens and settings for photorealism, for example "shot on Fujifilm X-T5, 35mm f/1.4" ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).
- Describe the role of each reference: subject from one, style from another ([BFL](https://docs.bfl.ai/guides/prompting_guide_flux2)).

## FLUX 2 Pro example prompts

**Prompt 1**

```text
Place the serum bottle from image 1 on the marble counter in image 2, label facing the camera, next to a folded hand towel in #9CAF88 sage green. Soft morning window light from the left, gentle shadows, shallow depth of field. Shot on Hasselblad X2D, 80mm lens, f/2.8.
```

**Prompt 2**

```text
A ceramic coffee mug in hex #C65D3B terracotta on a pale oak table, steam rising, morning light from a window on the left, a linen napkin in hex #F2EDE4 beside it. Shot on Fujifilm X-T5, 35mm f/1.4, sharp focus on the mug.
```

**Prompt 3**

```text
The sneaker from image 1 on a concrete step in the style of image 2, low angle, late afternoon sun, long shadows, the sole's colour exactly as in image 1.
```
