Outsourced photo/retouch + manual catalogs
Goal
Faster sample communication

Pain Points

1

Costly photo and retouch

Outsourced sample photography and retouching is slow and expensive.

2

Slow catalog production

Manual layout means each catalog revision takes days.

3

Fast style turnover

New styles launch faster than assets can keep up.

How We Built It

01

AI image retouching

Auto cutout, background swap and style unification with multi-background images.

02

Auto catalog layout

Auto layout catalogs from templates.

03

Bulk new-style updates

Bulk-generate assets for new styles.

Not betting on one AI — combining the right few

For a real business scenario, we don't lock in a single technical path up front. We evaluate candidate paths on the same benchmark, then design a hybrid so each path does what it's best at.

General LLM API

Public-cloud models such as GPT-4o / Qwen / DeepSeek

  • ✓Out-of-the-box, minimal integration cost, cheap to start
  • ✕Limited generalization to vertical domains, unstable field-level accuracy, separate compliance design
Best for cold start and quick validation

Industry fine-tuned model

Domain fine-tuning of open-source models on industry data

  • ✓Grasps industry semantics, much higher accuracy, private deployment
  • ✕Needs labeled data plus ongoing training and upkeep
Best as the primary path for high-frequency traffic

RAG + rule engine

Retrieval-augmented knowledge plus business rule checks

  • ✓Highly targeted, explainable, best latency and cost
  • ✕Requires continuous data-loop investment
Best for fallback and high-certainty scenarios

Fusion, not selection

What we deliver is not a single model but a fused pipeline of primary path + semantic correction + graceful fallback: routine cases are handled by the industry model in seconds; low-confidence fields are re-understood by an LLM; on service anomalies the system degrades to a general API and flags manual review — achieving accuracy, cost, latency and controllability at once.

An explainable, degradable, evolvable AI pipeline

We treat AI engineering as a pipeline, not a black box: every step has clear responsibilities, inputs/outputs and fallbacks. The five-step pipeline plus four-layer architecture below is the technical skeleton.
