Generative AI is a branch of artificial intelligence designed to create new content, such as text, images, music, or, in this case, code. Unlike traditional AI, which focuses on analysing existing data and providing insights, generative AI models are trained to produce original outputs based on patterns they’ve learned from vast datasets. In the context of software development, generative AI takes input prompts—like a few lines of code, a function name, or even a problem description—and generates relevant, usable code snippets, documentation, or even debugging suggestions.
Generative AI is transforming software development by enhancing and augmenting traditional coding practices. It's becoming an essential skill for software engineers, with courses and specialisations now available to help developers leverage their power in real-world software development.
At its core, generative AI relies on advanced models like transformers, which process large-scale data to understand the context and intent behind a prompt. These models leverage millions of lines of code from publicly available sources to provide developers with meaningful and context-aware suggestions.
Generative AI transforms software development by addressing common pain points that engineers and students face daily. Here’s why it matters:
The SDLC is the framework that guides developers through every stage of a software project, from planning to deployment. Generative AI has become a game-changer, improving productivity and accuracy across crucial phases. Let’s explore how generative AI tools make a tangible impact at each stage of the SDLC:
The planning phase sets the foundation for the entire project, and generative AI can speed up and make this step more precise.
By automating these steps, teams can save significant time and ensure every essential requirement is noticed.
The development phase is where generative AI tools truly shine, delivering efficiency gains and reducing the cognitive load on developers.
getUserData(), these tools can generate the entire function with parameters and logic.
Testing is a critical phase in the SDLC, and generative AI simplifies it by automating tedious and repetitive tasks.
Deployment is the final stage of the SDLC, where the software is delivered to end users or integrated into production. Generative AI enhances this phase by ensuring smoother and more reliable deployments.
Generative AI tools are efficient for improving productivity and simplifying everyday coding tasks. These tools can help you generate code faster, debug smarter, create documentation effortlessly, and build test cases efficiently. Let’s explore some actionable tips to maximise generative AI in your coding workflow.
Writing repetitive code can be time-consuming, but generative AI tools like GitHub Copilot are built to help you avoid this chore.
# Define a function to calculate the factorial of a number
def factorial(n):
Copilot might complete the code as follows:
if n == 0 or n == 1:
return 1
else:
return n * factorial(n - 1)
Debugging is one of software development's most challenging and time-consuming aspects, but tools like Snyk can make it significantly easier.
def divide(a, b):
return a / b
If you input this code into Snyk, it might flag the function and suggest adding error handling for cases where b = 0. The suggested correction could look like:
def divide(a, b):
if b == 0:
raise ValueError("Cannot divide by zero.")
return a / b
Creating detailed documentation for your code can be tedious but is essential for collaboration and future maintenance. Generative AI tools, such as OpenAI Codex, automate this process, enabling you to generate documentation alongside your code.
def validate_email(email):
# Logic to validate an email address
Using Codex, you can generate documentation like:
Function: validate_email(email)
Purpose: Validates an email address to ensure it matches standard email formatting.
Parameters:
- email (str): The email address to validate.
Returns:
- bool: True if the email is valid, False otherwise.
Writing unit tests and integration tests is vital but often repetitive. Generative AI tools speed up this process by automatically creating comprehensive test cases tailored to your code.
@app.route('/user/<int:id>', methods=['GET'])
def get_user(id):
# Logic to retrieve user by ID
By prompting a tool like Codex or ChatGPT with:
“Write unit test cases for a REST API endpoint that retrieves a user by ID,” it might generate the following test cases in Python:
def test_get_user_valid_id():
response = client.get('/user/1')
assert response.status_code == 200
assert response.json['id'] == 1
def test_get_user_invalid_id():
response = client.get('/user/999')
assert response.status_code == 404
def test_get_user_no_id():
response = client.get('/user/')
assert response.status_code == 400

Generative AI is a versatile tool that addresses common challenges in software development. From cleaning up messy code to quickly building prototypes, generative AI offers practical solutions that developers can integrate into their daily workflows. Here are some of the most impactful applications of generative AI in software development.
Over time, codebases can become cluttered with outdated structures, inconsistencies, and inefficiencies, resulting in technical debt. Generative AI tools can automate code refactoring to improve readability, simplify logic, and align code with modern standards.
How It Helps:
Example in Action:
Imagine a Python script with redundant nested loops:
for i in range(len(array)):
for j in range(i+1, len(array)):
if array[i] > array[j]:
array[i], array[j] = array[j], array[i]
A tool like GitHub Copilot might suggest replacing it with a more efficient and readable sorting algorithm, such as:
array.sort()
Why It Matters: Reducing technical debt and improving readability make the codebase easier to maintain and reduce the risk of bugs in the future.
Legacy codebases often pose significant challenges due to outdated syntax, deprecated libraries, or inefficient practices. Generative AI can assist in modernising such codebases by translating legacy code into contemporary programming languages or updating it to adhere to current standards.
How It Helps:
Example in Action:
A legacy JavaScript file using var for variable declarations might be updated to the modern let and const conventions:
// Original code
var count = 0;
var items = [];
AI tools can modernise it to:
let count = 0;
const items = [];
Why It Matters: Modernising legacy code ensures compatibility with newer systems, improves performance and facilitates integration with modern frameworks and tools.
Generative AI tools can identify performance bottlenecks in your code and offer optimisations to improve runtime efficiency. This is particularly useful for resource-intensive applications where even small optimisations can significantly impact.
How It Helps:
Example in Action:
Suppose you have a function that calculates Fibonacci numbers recursively:
def fibonacci(n):
if n <= 1:
return n
return fibonacci(n - 1) + fibonacci(n - 2)
An AI tool might suggest using an iterative approach or memoisation to improve runtime efficiency:
def fibonacci(n, memo={}):
if n in memo:
return memo[n]
if n <= 1:
return n
memo[n] = fibonacci(n - 1, memo) + fibonacci(n - 2, memo)
return memo[n]
Why It Matters: Performance optimisations can reduce resource consumption, improve scalability, and enhance the user experience.
Prototyping is a crucial phase in software development, allowing teams to test and validate ideas before full implementation. Generative AI accelerates this process by quickly generating working prototypes based on high-level descriptions.
How It Helps:
Example in Action:
Let’s say you want to prototype a chatbot using Python. By prompting a generative AI tool with:“Create a basic chatbot using Python and Flask,” the tool might generate:
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/chat', methods=['POST'])
def chat():
user_input = request.json.get('message')
response = "You said: " + user_input
return jsonify({'response': response})
if __name__ == '__main__':
app.run(debug=True)
This basic chatbot can be expanded or refined into a full-fledged feature.
Why It Matters: Rapid prototyping helps teams experiment with ideas, get early feedback, and iterate more effectively, leading to more innovative and user-centric solutions.
