Flux 2 Lora Gallery Face To Full Portrait is BFL's intelligent image editing model. Transform, retouch, and reimagine existing images using text prompts - from background replacement to artistic style conversion.

Input
The prompt describing the full portrait to generate from the face.

PNG, JPEG, WebP, or GIF · 20 MiB maximum each

The URL of the cropped face image.
020
The CFG (Classifier Free Guidance) scale. Controls how closely the model follows the prompt. Range: 0 to 20.
450
The number of inference steps to perform. Range: 4 to 50.
The format of the output image Allowed values: png, jpeg.
02
The strength of the face to full portrait effect. Range: 0 to 2.
The aspect ratio of the generated image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.
Random seed for reproducibility. Same seed with same prompt will produce same result.

API README

Flux 2 Lora Gallery

Flux 2 Lora Gallery is a specialized FLUX.2 LoRA workflow for face to full portrait. It combines the selected adaptation with FLUX.2’s strong prompt understanding and photorealistic scene construction, concentrating the model on a repeatable production task instead of asking a general image endpoint to infer the workflow from a broad prompt.

Use this route when the input assets and final deliverable match face to full portrait exactly. Explain the desired composition and presentation, then state the visual facts that must stay consistent—such as architecture, identity, geometry, branding, or material appearance. The specialization supplies task knowledge, while the brief controls the specific creative result.

Highlights

  • Portrait extension. Builds a complete portrait composition from a supplied facial reference.
  • Identity continuity. Retains recognizable facial structure while generating body, clothing, pose, and setting.
  • Anatomically coherent completion. Extends beyond the crop with plausible proportions and spatial relationships.
  • Art-directed presentation. Adapts wardrobe, lighting, background, and camera treatment to the requested portrait style.

When to Use

✅ Good fit❌ Consider alternatives
The project needs this exact generation or editing routeThe intended task belongs to video, audio, or 3D media
Available references match every required local fieldRequired source assets or rights are unavailable
The brief can specify composition, color, and finishOutput must be deterministic at pixel level
Supported dimensions and formats fit final placementDelivery requires unsupported canvas specifications
An asynchronous generated image fits productionA live frame-synchronous response is mandatory

Prompt Guide

Write a complete visual brief: identify the subject and references, define composition and viewpoint, describe lighting, palette, materials, typography, and finish, then list exact preservation constraints. FLUX.2 Klein does not rely on prompt upsampling, so use clear descriptive sentences rather than sparse keywords.
