introduction

 

In the process of developing AI Agent, I deeply realized that many ways of thinking are different from traditional development. That is to say, with the breakthrough of big model technology, the AI ​​application development paradigm is undergoing a paradigm shift from rule-driven to data-driven .

As a paradigm shift, its process and impact are far-reaching. This article analyzes the essence of the change from four dimensions : technical architecture, development process, product form, and business logic , and compares the differences in traditional software engineering to provide practitioners with a systematic upgrade path reference.

I hope that the software engineers, product managers, and business leaders who read this article can carefully understand the differences and embrace the commercialization of application development driven by AI big models as early as possible.

This is not a multiple-choice question, but a required question.


01


Technical architecture innovation: from deterministic logic to probabilistic reasoning

Traditional software engineering builds deterministic systems based on Boolean logic, while AI applications rely on probabilistic models to implement non-deterministic reasoning. The difference between the two is reflected in:

Dimensions

Traditional applications

AI Applications

Core Components

Functional module + database

Data + Big Models + Feedback Loops

Failure Handling

Exception Capture

Confidence Threshold Filtering

Iteration Mechanism

Version Control

Continuous training

Technology stack migration example :

  • Traditional three-piece set : Java + MySQL + REST API

  • New AI infrastructure : PyTorch + feature library + model service

Typical architecture comparison :

Refactoring the development process: Data engineering becomes the critical path

The waterfall model of traditional software development is evolving towards the data flywheel model of AI development:

Development stage comparison

life cycle

Traditional Development

AI Development

Demand Analysis

Functional Specifications

Data feasibility verification

Implementation Phase

Writing business logic code

Build feature engineering

Test verification

Unit testing/integration testing

Model Validation + Bias Detection

Maintenance phase

Bug fixes + feature extensions

Data drift monitoring

Key Challenges:

  • Data-model decoupling dilemma : Traditional monolithic architecture is difficult to support hot model updates.

  • Risk of technical debt multiplication : Incorrect data labeling strategies may cause the cost of subsequent iterations to increase exponentially.


03


Product form evolution: from functional solidification to capability growth

Traditional software functional boundaries are predefined by code, while AI applications have dynamic capability expansion features:

Product Capabilities Matrix

index

Traditional software

AI Applications

Functional determinism

Strict mapping of input and output

The output has probability distribution characteristics

User Interaction

Form/Button Driver

Natural language dialogue + multimodal input

Value Curve

Function superposition linear growth

Data accumulation brings performance index improvement

Typical cases :

  • Traditional CRM : Sales funnel rules need to be manually configured

  • AI-driven CRM : AI automatically identifies high-intent customers and generates follow-up strategies


04


Subversion of business logic: from license sales to value sharing

The big model drives the software business model from product delivery to service operation . The core differences are as follows:

Business Model Comparison

Dimensions

Traditional Model

AI Mode

Value carrier

Software Features

Data assets + model intelligence

Charging Model

license

Billed by call volume

Customer Relationship

Version upgrade sales

Continuous Proof of Value

A systematic summary of the differences between AI and traditional applications

Based on the previous discussion, AI applications show essential differences in four major aspects:

1. Design phase

  • Requirements definition : moving from functional rule description to learnable pattern definition

  • Core Objects : From Database ER Diagram Design to Data Pipeline Architecture Design

  • Verification logic : From flowchart verification to minimum viable model (MVP Model) verification

2. Development phase

  • Technology stack : From traditional frameworks to PyTorch/TensorFlow ecosystem

  • Code characteristics : moving from deterministic logic to probabilistic output management

  • Iteration mechanism : shift from version release to data closed-loop driven continuous iteration

3. Deployment phase

  • Resource requirements : shifting from CPU optimization to GPU/TPU acceleration architecture

  • Operation and maintenance focus : shifting from service status monitoring to model performance monitoring

  • Security compliance : Extending from code vulnerability protection to model robustness assurance

4. User Use

  • Interaction mode : From form filling to natural language dialogue

  • Expectation Management : Moving from Functional Certainty to Probabilistic Outcome Education

  • Feedback value : From defect reports to data sources for model training

Technology Evolution Suggestions

1. Architecture transformation:

  • Build an enterprise-level feature library to realize data assetization

  • Using model service grid to support multi-model collaborative reasoning

2. Organizational upgrade:

  • Establishing MLOps engineer positions to connect data science and software engineering

  • Establish a model ethics review committee to prevent the risk of algorithmic bias

3. Business Innovation:

  • Designing a value-based API billing model

  • Developing the Model Monitoring as a Service (MMaaS) platform to create a second growth curve

Conclusion

The paradigm shift caused by big models is reshaping the foundation of the software industry. Enterprises need to face up to the differences in the design, development, deployment, and use of AI applications, and make systematic layouts from the three aspects of technical architecture, organizational process, and business model. Those enterprises that first complete the closed loop of data assetization-model service-business sustainability will occupy the commanding heights of the value chain in the intelligent era.
