Client Profile

Industry
F&B · bakery chain
Scale
8 stores · 30k members
Current
Coarse members + manual holiday campaigns
Goal
More member value and holiday sales

Pain Points

1

Coarse member tags

No preference tags means outreach misses the mark.

2

Time-consuming holiday campaigns

Every holiday needs copy, posters and pushes from scratch.

3

Too many dormant members

Members take coupons and never return, dragging repeat rates.

How We Built It

01

Member segmentation

Tag members by frequency, category and ticket size.

02

Auto holiday campaigns

Auto-generate holiday copy, posters and pushes.

03

Dormant-member reactivation

Differentiated offers based on why members went dormant.

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.
