How AI‑Powered LoRA Techniques Supercharged a September Recruitment Campaign Design

Project Background

To meet the high demand of the September recruitment season, 58.com launched a special hiring event aimed at driving user conversion, increasing user value, and improving next‑day retention.

Design Strategy

Strengthen brand image with dual reinforcement of brand symbols and colors.

Visual concept focuses on a multi‑industry, job‑rich scene for the September hiring peak.

Technical exploration combines multiple LoRA applications and a custom LoRA model to boost design efficiency.

Implementation Details

Brand Reinforcement

Maintain the glass‑like brand texture and a transparent, positive emotional visual language, using an 8:2 color ratio.

Visual Concept

Background layer uses newspaper and message‑box elements to convey abundant job information; the character layer features multiple figures to represent diverse positions; the foreground adds flying gold coins to enhance the event atmosphere.

Technical Exploration

Multiple LoRA models (glass texture, character, newspaper background) are combined via the Additional Networks plugin, allowing weighted control of each model to generate high‑quality images directly from Stable Diffusion and then fine‑tune them.

Sketch & Composition

After clarifying the visual concept, reference images were collected and composited in Photoshop to build the layout.

Prompt Engineering

Reverse‑engineered prompts were crafted to guide the AI, covering aspects such as texture, subject, clothing, emotion, tone, and environment.

Pose Extraction

Four character poses were selected from extensive searches and extracted using OpenPose for accurate body and facial expression control.

Brand Symbol Control

Segmentation masks were used to position characters and apply the glass‑texture symbol precisely.

Multiple LoRA Application

The Additional Networks plugin sets different weight ratios for each LoRA; the character LoRA receives a higher weight, while the background LoRA is fine‑tuned for optimal effect.

Initial Draft Completion

AI‑generated images were reviewed, the best draft selected, and local re‑painting corrected facial and hand details; an upscaling script added final detail and consistency.

Photoshop Refinement

Final touches added gold‑coin elements and the main title to enhance the overall atmosphere.

Results

The September recruitment campaign met all performance expectations; the AI‑driven workflow not only boosted business metrics but also demonstrated promising potential for future operational applications.

Additional Networks Plugin Overview

The plugin enables mixing multiple LoRA models, provides download and installation instructions, and specifies that LoRA files must reside in extensions\sd-webui-additional-networks\models\lora for activation.
