Generative AI is revolutionizing the way we create content, from writing and art to music and code. With models like GPT, DALL·E, Stable Diffusion, and MusicGen, AI can now produce human-like text, generate stunning visuals, compose music, and even write functioning code. But how do you get started?
The easiest way to begin experimenting is by using Google Colab, a free cloud-based Jupyter notebook environment. It offers access to Python, GPUs, and an intuitive interface that makes it ideal for running AI models without installing anything locally.
In this article, we’ll explore generative AI projects you can run in Google Colab, with step-by-step instructions, useful code snippets, and real-world applications.
Why Use Google Colab for Generative AI?
- Free compute (GPU/TPU) access
- No installation required
- Built-in libraries and support for PyTorch, TensorFlow, Transformers
- Easy file I/O with Google Drive
- Sharable and collaborative notebooks
Getting Started: Setup in Google Colab
Before diving into projects, here are the basic steps:
- Go to https://colab.research.google.com
- Click “New Notebook”
- Rename the file (e.g.,
generative_ai_projects.ipynb) - Go to
Runtime > Change runtime typeand select GPU - Install dependencies using
pip installin code cells
Example:
!pip install transformers diffusers torch torchvision
Now you’re ready to begin your first project!
Project 1: Text Generation with GPT-2
Goal
Generate coherent paragraphs of text based on a prompt using OpenAI’s GPT-2.
Why It’s Useful
Text generation models can assist with:
- Creative storytelling
- Content idea brainstorming
- Writing code comments or documentation
- Simulating chatbot responses
Steps
Install the required libraries:
!pip install transformers
Then use the following code:
from transformers import pipeline
generator = pipeline("text-generation", model="gpt2")
prompt = "In a distant future, humans and AI coexist peacefully."
output = generator(prompt, max_length=100, num_return_sequences=1)
print(output[0]['generated_text'])
Tips
- Use
gpt2-mediumorgpt2-largefor better quality (but they consume more RAM) - You can add custom prompt templates to control the story tone or structure
- Consider adding randomness using
temperature=0.7
Applications
- Story generation
- Blog post drafting
- Conversational agents
Project 2: Image Generation with Stable Diffusion
Goal
Generate photorealistic or artistic images from natural language prompts using Stable Diffusion.
Why It’s Useful
Text-to-image generation enables:
- AI-driven art
- Visual prototypes for designers
- Rapid content creation for marketing
Setup
Install dependencies:
!pip install diffusers transformers accelerate scipy safetensors
Then run the image generation code:
from diffusers import StableDiffusionPipeline
import torch
pipe = StableDiffusionPipeline.from_pretrained(
"CompVis/stable-diffusion-v1-4",
torch_dtype=torch.float16
)
pipe = pipe.to("cuda")
prompt = "a futuristic city at sunset, digital art"
image = pipe(prompt).images[0]
image.show()
Tips
- Use highly descriptive prompts for better results
- Combine style keywords (e.g., “in the style of Studio Ghibli”)
- Save outputs using
image.save('filename.png')
Applications
- AI art
- Concept design
- Book or game illustration
Project 3: AI-Powered Music Composition
Goal
Generate original music tracks from text prompts using MusicGen.
Why It’s Useful
Music generation is great for:
- YouTube intros
- Podcast background music
- Indie game soundtracks
Setup
!pip install git+https://github.com/facebookresearch/audiocraft.git
Then run:
from audiocraft.models import MusicGen
model = MusicGen.get_pretrained('facebook/musicgen-small')
model.set_generation_params(duration=10)
output = model.generate(["a cheerful lo-fi beat with guitar"])
Note: Output is a waveform array. Use scipy.io.wavfile.write() to save to a .wav file.
Tips
- Choose genre-specific prompts: “orchestral symphony”, “trap beat”
- Limit duration to 10–30 seconds on free Colab tier
- Consider upgrading to
musicgen-mediumfor richer results
Applications
- Background music for videos
- Jingle generation
- Audio branding
Project 4: Image Captioning
Goal
Automatically describe an image in human-like text.
Why It’s Useful
Image captioning is essential for:
- Improving accessibility (e.g., alt text for screen readers)
- Metadata generation for media libraries
- Automated content tagging
Setup
!pip install transformers
Code Example
from transformers import BlipProcessor, BlipForConditionalGeneration
from PIL import Image
import requests
url = "https://huggingface.co/datasets/nateraw/image-captioning-demo/resolve/main/example.jpg"
image = Image.open(requests.get(url, stream=True).raw)
processor = BlipProcessor.from_pretrained("Salesforce/blip-image-captioning-base")
model = BlipForConditionalGeneration.from_pretrained("Salesforce/blip-image-captioning-base")
inputs = processor(images=image, return_tensors="pt")
out = model.generate(**inputs)
print(processor.decode(out[0], skip_special_tokens=True))
Applications
- Accessibility
- Content tagging
- Social media automation
Project 5: Code Generation
Goal
Use generative models to create functioning code snippets based on natural language prompts.
Why It’s Useful
Code generation models help:
- Accelerate development
- Generate boilerplate code
- Learn programming syntax and logic
Setup
!pip install transformers
Example
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("replit/code-v1-3b")
model = AutoModelForCausalLM.from_pretrained("replit/code-v1-3b")
prompt = """# Python function to check if a number is prime"""
inputs = tokenizer(prompt, return_tensors="pt")
