FLUX Schnell
FLUX.1 [schnell] by Black Forest Labs is an advanced text-to-image tool that transforms descriptions into amazing visuals. Schnell is the quickest version, optimized for local development and personal projects.
Overview
Black Forest Labs, founded by former Stability AI team members, designed FLUX to push AI image generation forward. Using a hybrid system with multimodal and parallel diffusion transformer blocks and 12 billion parameters, FLUX creates images with great detail and accuracy.
FLUX Versions:
- FLUX1.1 [pro]: The premium version, offering ultra-fast image creation with excellent quality and precision—perfect for big projects where speed and efficiency matter.
- FLUX1 [dev]: A free, guidance-distilled model for non-commercial use. It’s efficient and delivers nearly the same quality as the pro version, making it great for developers and researchers.
- FLUX1 [schnell]: The quickest version, optimized for local development and personal projects. Released under the Apache 2.0 license, it’s a great pick for solo creators.
FLUX Schnell is a 12B param rectified flow transformer distilled from FLUX.1 [pro] for 4 step generation. It can be run locally in ComfyUI. There are quantized (GGUF) versions available for lower hardware requirements.
FLUX Schnell provides lesser realism than more powerful versions, but still very good for the job, and particularly nice with flat vector style illustrations.
Like many others, it currently does well with short texts (like, one word, up to 10 letters) and gets confused mixing up, omitting or repeating letters when you're trying full sentences.

Here’s the gist of what Redditors are saying:
Strengths of Each Model:
- Flux Dev: Great at creating realistic scenes, especially people and nature. But the results can feel too uniform or stiff.
- Flux Schnell: Shines with creative, inorganic designs—think robotic insects or abstract art. It’s a go-to for concept artists.
Prompt Adherence:
- Schnell isn’t strict about following prompts but delivers visually stunning work.
- Dev sticks to the prompt better but misses the artistic flair Schnell brings.
Commercial Viability:
- Schnell: Fully open with an Apache 2.0 license—commercial use and fine-tuning are a go.
- Dev: Restrictive license blocks commercial derivatives like LoRAs, limiting its appeal.
User Sentiments:
- Schnell wins for artistic projects and adaptability.
- Dev is better for precise, technical tasks, making it more niche.
Comparisons to Other Models:
- MidJourney v6.1: Artsy but struggles with strict prompts.
- SD3 Large: Realistic but less creative than Schnell.
- Stable Image Ultra: Overdoes colors and feels like SD3’s twin.
Community Insights:
- Guidance scale settings matter a lot—lowering them can boost Schnell’s output.
- Schnell’s open license makes it a favorite for hybrid models and experiments.
Takeaway:
Flux Schnell is the top pick for artists and commercial use, while Flux Dev fits precision-focused, non-commercial tasks. Most users favor Schnell for its flexibility and creativity.
A young woman sitting at a rustic wooden table in a cozy, softly lit café. Her head rests on her hand, elbow propped on the table, her expression distant and bored. Strands of her wavy chestnut hair frame her face, catching the golden glow of the late afternoon sun streaming through a large window beside her. The table is scattered with a cup of steaming coffee, a half-read book, and a notebook with scribbled notes. Behind her, the blurred bustle of the café contrasts sharply with her stillness, creating a sense of detachment. Cinematic framing focuses on her from a slight angle, emphasizing the slant of her gaze and the wistfulness in her eyes. The warm ambiance is accented by bokeh light effects, with muted tones of beige, cream, and soft green dominating the background, adding a dreamy, introspective mood.Generated on January 12, 2025:
Medium shot, fish-eye lens. Shallow depth of field creates a focus on the robots taking selfies while at the top of the mountain. All robots huddled together while taking a group selfie picture. Goldy is a red 1950s retro robot monster, slightly rusty. Dolbus is a sleek futuristic humanoid robot with rounded features, black and steel look and taller than the rest. Bingus is a copper steampunk robot with big eyes and a stylish hat posing with crossed arms, chin up, projecting attitude. All robots appear happy, smiling directly at the camera. The mood is jolly and humorous.Generated on January 12, 2025:
