Flux AI Image Generation: Settings, LoRA and Perfect Prompt Tips

Akos — $1,510 in first-month Fanvue revenue from zero, founder of the AI OFM community (387+ members)

Realistic image generated with the Flux AI model using optimized settings — AI-generated image — in the style of the settings covered in this article.

Why Flux?

In 2026, Flux is the best open-source image generator for photorealistic content. All 1995 AI OFM prompts are optimized for it — and for good reason.

Flux model variants

Flux.1 Dev — the core model, the best balance of quality and speed
Flux.1 Pro — higher quality, slower, available via API
Flux.1 Schnell — fast (4 steps), lower quality, great for testing

For OFM content, Flux.1 Dev is the best pick — fast enough, with excellent quality.

An AI character's images in one gallery, all with the same face — One character, many images, the same face — from the video course.

LoRA — custom styles and faces

A LoRA (Low-Rank Adaptation) lets you train a custom style or face into the model. It's the key to a consistent AI persona.

Face LoRA: trained on 15-30 reference images, it then generates the same face every time — the alternative is AI face swap technology
Style LoRA: a defined visual style (e.g. "editorial photoshoot")
Outfit/pose LoRA: trains a specific outfit or body position

Prompt structure for Flux

Flux understands natural language best (no need for tag lists like with SDXL):

Subject: "A candid photo of a young woman in a white tank top..."
Setting: "...in a modern minimalist apartment, morning light through windows"
Camera: "...shot on Sony A7III, 85mm f/1.8, shallow depth of field"
Quality: "...photorealistic, 8k, sharp focus, natural skin texture"
