# Flux.1 
Flux.1은 이미지 생성 AI 분야에서 주목받고 있는 모델이다. **Black Forest Labs**에서 개발하였으며, "텍스트를 기반으로 고품질의 이미지를 생성"하는데 특화되어 있다.

**Stable Diffusion** 과 함께 가장 주목 받고 있는 모델이다. Stable Diffusion에 비해서 더 높은 품질의 이미지를 만들 수 있다. SD를 이용해서 인물을 만들 경우 얼굴 표정, 손, 발 등 세부적인 디테일에서 어색한 부분이 나타날 수 있다. 이때 문에 여러 테스트를 거치거나 확장을 설치해서 보정을 해야 하는데, Flux.1은 특히 인물 생성에서 즉시 사용해도 될 만큼의 높은 성능을 보여준다.

Stable Diffusion 설치 문서는 [스테이블 디퓨전 설치 및 사용해보기](https://www.joinc.co.kr/w/sd_install) 문서를 참고하자.

# 설치 환경
Flux.1은 윈도우즈, 리눅스, 맥 어디든 설치 할 수 있다. 이 문서는 "리눅스 운영체제"를 기준으로 테스트했다.
 1. 운영체제: 우분투 리눅스 24.10
 2. NVIDIA GeForce RTX 4060 Ti 16G
 3. 32G RAM
 4. AMD Ryzen 5 5600X 6- Core

# Stable diffusion webui forge
**Stable Diffusion WebUI Forge**는 Stable Diffusion 모델을 기반으로 하는 생성 이미지 AI를 빠르고 편리하게 사용 할 수 있도록 도와주는 **플러그인 관리 시스템**이다. 이러한 확장 가능한 플러긍린 기능을 이용해서 Flux.1 같은 모델도 쉽게 사용 할 수 있다.

생성 이미지 모델은 매우 큰 크기를 가지고 있다. aria2를 이용하면 좀 더 빠르게 모델을 다운로드 할 수 있다.
```
sudo apt-get update
sudo apt-get upgrade -y
```

```
sudo apt-get install -y aria2
```

**Stable diffusion webui forge 저장소**를 clone 한다.
```
git clone https://github.com/lllyasviel/stable-diffusion-webui-forge
cd stable-diffusion-webui-forge
```

## flux1-dev 설치 및 실행
aria2c는 wget과 같은 파일 다운로드 프로그램이다. HTTP, HTTPS, FTP 프로토콜 뿐만 아니라 BitTorrent, Metalink와 같은 추가 프로토콜도 지원한다. 또한 여러 소스에서 동시에 파일을 받아 분할 다운로드 할 수 있는 기능이 있어서 다운로드 속도를 높이는데 유리하다.

aria2c로 
```
aria2c -c -x 16 -s 16 -k 1M https://huggingface.co/lllyasviel/flux1-dev-bnb-nf4/resolve/main/flux1-dev-bnb-nf4-v2.safetensors -d models/Stable-diffusion -o flux1-dev-bnb-nf4-v2.safetensors

Design a hyper-realistic scene of ['Penempatan Usang Ditebing Pergunungan,'] showcasing [a weathered wooden house teetering on the edge of a rugged cliff], viewed from a low angle. The house features a small balcony with laundry hanging out to dry, casting sharp shadows under the bright midday sun. Lush greenery envelops the base of the cliff, while the expansive landscape is mostly hidden by dense foliage. Although the day is clear, the scene evokes an eerie and isolated atmosphere, with sharp, high-contrast details amplifying the sense of desolation and solitude.

Capture a street food vendor in Tokyo at night, shot with a wide-angle lens (24mm) at f/1.8. Use a shallow depth of field to focus on the vendor’s hands preparing takoyaki, with the glowing street signs and bustling crowd blurred in the background. High ISO setting to capture the ambient light, giving the image a slight grain for a cinematic feel.

Depict a cozy, warmly lit bookstore cafe on a rainy evening. The atmosphere should be inviting and nostalgic, with soft yellow lighting from vintage lamps illuminating rows of well-worn books. Show patrons reading in comfortable armchairs, steam rising from their coffee cups. The large front window should reveal a glistening wet street outside, with blurred lights from passing cars. Emphasize the contrast between the warm interior and the cool, rainy exterior.
```

Layer 1 (Background): Depict a city of interconnected floating islands suspended in a pastel sky. The islands should have a mix of whimsical architecture styles, from towering spires to quaint cottages. Show distant airships and flying creatures in the background.

Layer 2 (Middle ground): Focus on the main marketplace area. Illustrate a wide plaza with colorful stalls and shops selling exotic goods. Include floating platforms that serve as walkways between different sections of the market.

Layer 3 (Foreground): Populate the scene with a diverse array of fantasy creatures and humanoids. Show vendors calling out to customers, children chasing magical floating bubbles, and a street performer juggling balls of light. In the immediate foreground, depict a detailed stall selling glowing potions and mystical artifacts.

Atmosphere: The overall mood should be vibrant and magical, with soft, ethereal lighting that emphasizes the fantastical nature of the scene.

Create an image that fuses the precision of M.C. Escher’s impossible geometries with the bold colors and shapes of Wassily Kandinsky’s abstract compositions. The subject should be a surreal cityscape where buildings seamlessly transform into musical instruments. Use Escher’s techniques to create paradoxical perspectives and interconnected structures, but render them in Kandinsky’s vibrant, non-representational style. Incorporate musical notations and abstract shapes that flow through the scene, connecting the architectural elements. The color palette should be rich and varied, with particular emphasis on deep blues, vibrant reds, and golden yellows.
```

```
Create a surreal advertisement poster for a fictional time travel agency. The background should depict a swirling vortex of clock faces and historical landmarks from different eras. In the foreground, place large, bold text that reads “CHRONO TOURS: YOUR PAST IS OUR FUTURE” in a retro-futuristic font. The text should appear to be partially disintegrating into particles that are being sucked into the time vortex. Include smaller text at the bottom with fictional pricing and the slogan “History is just a ticket away!”

Create an image in the style of Vincent van Gogh’s “Starry Night,” but replace the village with a futuristic cityscape. Maintain the swirling, expressive brushstrokes and vibrant color palette of the original, emphasizing deep blues and bright yellows. The city should have tall, glowing skyscrapers that blend seamlessly with the swirling sky.
