Flux Kontext Guide: Edit, Restyle & Preserve Identity

Kontext models do something that standard generation models cannot: they edit existing images while preserving the identity of the subject. Upload a photo of a person, describe how you want it changed, and Kontext transforms the image while keeping the person recognizable.

How Kontext Differs from Standard Generation

Standard models like Flux Dev or Seedream generate images from scratch based on a text prompt. If you want a specific person, you cannot reliably get the same face twice.

Kontext takes an existing image as context. It understands who or what is in the image and modifies it according to your instructions while maintaining identity continuity.

What You Can Do with Kontext

Change Outfits

Upload a headshot and describe a different outfit: "wearing a navy blue suit and red tie" or "in a casual white t-shirt and denim jacket."

Change Backgrounds

Keep the subject identical but transform the setting: "on a tropical beach at sunset" or "in a modern office with floor-to-ceiling windows."

Restyle the Image

Transform the artistic style while keeping the subject: "as an oil painting in the style of classical portraiture" or "as a comic book illustration."

Adjust Lighting and Mood

"With dramatic studio lighting and dark background" or "in warm golden hour sunlight."

Prompting Tips for Kontext

Describe the Change, Not the Whole Scene

Kontext already has the image context. Your prompt should describe what you want different, not re-describe the entire scene.

Good: "Change the background to a mountain landscape at sunset" Less effective: "A person standing in front of mountains with a sunset, wearing the same clothes" (re-describing what Kontext already sees)

Be Specific About What to Preserve

If you want everything except the background to stay the same, say so: "Keep the person and their outfit exactly the same, only change the background to..."

Start Simple

Begin with single changes — just the background, just the outfit, just the style. Multiple simultaneous changes are harder for the model to handle consistently.

Choosing a Kontext Model

• ●Dev-Fast (4 credits) — Good for quick iterations and testing edits
• ●Dev (5 credits) — Better quality, slightly slower
• ●Pro (8 credits) — Recommended for important edits. Strong identity preservation.
• ●Max (15 credits) — Maximum fidelity for critical work

Common Use Cases

• ●LinkedIn headshots — Change background or outfit without a new photo shoot
• ●Marketing variations — Same model, different settings or outfits
• ●Product photography — Same product, different environments
• ●Creative portfolios — Restyle photos in different artistic styles

Kontext opens up editing possibilities that were previously only available through expensive photo shoots or complex manual editing.
