In the ever-evolving landscape of artificial intelligence, one name has stood out prominently in recent years: transformers. These powerful models have transformed the way we approach generative tasks in AI, pushing the boundaries of what machines can create and imagine. In this article, we will delve into the advanced applications of transformers in generative AI, exploring their inner workings, real-world use cases, and the groundbreaking impact they have had on the field.
This article was published as a part of the Data Science Blogathon.
Before we dive into the things that are advanced, let’s take a moment to understand what transformers are and how they’ve become a driving force in AI.
Transformers, at their core, are deep learning models designed for the data, which is sequential. They were introduced in a landmark paper titled “Attention Is All You Need” by Vaswani et al. in 2017. What sets transformers apart is their attention mechanism, which allows them to find or recognize the entire context of a sequence when making predictions.
This innovation helps in the revolution of natural language processing (NLP) and generative tasks. Instead of relying on fixed window sizes, transformers could dynamically focus on different parts of a sequence, making them perfect at capturing context and relationships in data.
Transformers have found their greatest fame in the realm of natural language generation. Let’s explore some of their advanced applications in this domain.
Generative Pre-trained Transformers 3 (GPT-3) needs no introduction. With its 175 billion parameters, it’s one of the largest language models ever created. GPT-3 can generate human-like text, answer questions, write essays, and even code in multiple programming languages. Beyond GPT-3, research continues into even more massive models, promising even greater language understanding and generation capabilities.
Code Snippet: Using GPT-3 for Text Generation
import openai
# Set up your API key
api_key = "YOUR_API_KEY"
openai.api_key = api_key
# Provide a prompt for text generation
prompt = "Translate the following English text to French: 'Hello, how are you?'"
# Use GPT-3 to generate the translation
response = openai.Completion.create(
engine="text-davinci-002",
prompt=prompt,
max_tokens=50
)
# Print the generated translation
print(response.choices[0].text)
This code sets up your API key for OpenAI’s GPT-3 and sends a prompt for translation from English to French. GPT-3 generates the translation, and the result is printed.
Transformers have powered the next generation of chatbots and virtual assistants. These AI-powered entities can engage in human-like conversations, understand context, and provide accurate responses. They are not limited to scripted interactions; instead, they adapt to user inputs, making them invaluable for customer support, information retrieval, and even companionship.
Code Snippet: Building a Chatbot with Transformers
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
# Load the pre-trained GPT-3 model for chatbots
model_name = "gpt-3.5-turbo"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
# Create a chatbot pipeline
chatbot = pipeline("text-davinci-002", model=model, tokenizer=tokenizer)
# Start a conversation with the chatbot
conversation = chatbot("Hello, how can I assist you today?")
# Display the chatbot's response
print(conversation[0]['message']['content'])
This code demonstrates how to build a chatbot using transformers, specifically the GPT-3.5 Turbo model. It sets up the model and tokenizer, creates a chatbot pipeline, starts a conversation with a greeting, and prints the chatbot’s response.
Transformers are used extensively in content generation. Whether it’s creating marketing copy, writing news articles, or composing poetry, these models have demonstrated the ability to generate coherent and contextually relevant text, reducing the burden on human writers.
Code Snippet: Generating Marketing Copy with Transformers
from transformers import pipeline
# Create a text generation pipeline
text_generator = pipeline("text-generation", model="EleutherAI/gpt-neo-1.3B")
# Provide a prompt for marketing copy
prompt = "Create marketing copy for a new smartphone that emphasizes its camera features."
marketing_copy = text_generator(prompt, num_return_sequences=1)
# Print the generated marketing copy
print(marketing_copy[0]['generated_text'])
This code showcases content generation using transformers. It sets up a text generation pipeline with the GPT-Neo 1.3B model, provides a prompt for generating marketing copy about a smartphone camera, and prints the generated marketing copy.
With architectures like DALL-E, transformers can generate images from textual descriptions. You can describe a surreal concept, and DALL-E will generate an image that matches your description. This has implications for art, design, and visual content generation.
Code Snippet: Generating Images with DALL-E
# Example using OpenAI's DALL-E API (Please note: You would need valid API credentials)
import openai
# Set up your API key
api_key = "YOUR_API_KEY_HERE"
# Initialize the OpenAI API client
client = openai.Api(api_key)
# Describe the image you want to generate
description = "A surreal landscape with floating houses in the clouds."
# Generate the image using DALL-E
response = client.images.create(description=description)
# Access the generated image URL
image_url = response.data.url
# You can now download or display the image using the provided URL
print("Generated Image URL:", image_url)
This code uses OpenAI’s DALL-E to generate an image based on a textual description. You provide a description of the image you want, and DALL-E creates an image that matches it. The generated image is saved to a file.
Transformers can help create music. Like MuseNet from OpenAI; they can make new songs in different styles. This is exciting for music and art, giving new ideas and chances for creativity in the music world.
Code Snippet: Composing Music with MuseNet
# Example using OpenAI's MuseNet API (Please note: You would need valid API credentials)
import openai
# Set up your API key
api_key = "YOUR_API_KEY_HERE"
# Initialize the OpenAI API client
client = openai.Api(api_key)
# Describe the type of music you want to generate
description = "Compose a classical piano piece in the style of Chopin."
# Generate music using MuseNet
response = client.musenet.compose(
prompt=description,
temperature=0.7,
max_tokens=500 # Adjust this for the desired length of the composition
)
# Access the generated music
music_c = response.choices[0].text
print("Generated Music Composition:")
print(music_c)
This Python code demonstrates how to use OpenAI’s MuseNet API to generate music compositions. It starts by setting up your API key, describing the type of music you want to create (e.g., classical piano in the style of Chopin), and then calls the API to generate the music. The resulting composition can be accessed and saved or played as desired.
Note: Please replace “YOUR_API_KEY_HERE” with your actual OpenAI API key.
In the fast-changing world of AI, advanced transformers are leading the way in exciting developments in creative AI. Models like MUSE-NET and DALL-E are going beyond just understanding language and are now getting creative, coming up with new ideas, and generating different kinds of content.
MUSE-NET is a fantastic example of what advanced transformers can do. Created by OpenAI, this model goes beyond the usual AI capabilities by making its own music. It can create music in different styles, like classical or pop, and it does a good job of making it sound like it was made by a human.

from muse_net import MuseNet
# Initialize the MUSE-NET model
muse_net = MuseNet()
compose_l = muse_net.compose(style="jazz", length=120)
compose_l.play()
DALL-E, made by OpenAI, is a groundbreaking creation that brings transformers into the world of visuals. Unlike regular language models, DALL-E can make pictures from written words. It’s like a real artist turning text into colorful and creative images.
Here’s an example of how DALL-E can bring the text to life:
from dalle_pytorch import DALLE
# Initialize the DALL-E model
dall_e = DALLE()
# Generate an image from a textual description
image = dall_e.generate_image("a surreal landscape with floating islands")
display(image)
CLIP by OpenAI combines vision and language understanding. It can comprehend images and text together, enabling tasks like zero-shot image classification with text prompts.
import torch
import clip
# Load the CLIP model
device = "cuda" if torch.cuda.is_available() else "cpu"
model, transform = clip.load("ViT-B/32", device)
# Prepare image and text inputs
image = transform(Image.open("image.jpg")).unsqueeze(0).to(device)
text_inputs = torch.tensor(["a photo of a cat", "a picture of a dog"]).to(device)
# Get image and text features
image_features = model.encode_image(image)
text_features = model.encode_text(text_inputs)
CLIP combines vision and language understanding. This code loads the CLIP model, prepares image and text inputs, and encodes them into feature vectors, allowing you to perform tasks like zero-shot image classification with text prompts.
T5 models treat all NLP tasks as text-to-text problems, simplifying the model architecture and achieving state-of-the-art performance across various tasks.

model = T5ForConditionalGeneration.from_pretrained("t5-small")
tokenizer = T5Tokenizer.from_pretrained("t5-small")
# Prepare input text
input_text = "Translate English to French: 'Hello, how are you?'"
# Tokenize and generate translation
input_ids = tokenizer.encode(input_text, return_tensors="pt")
translation = model.generate(input_ids)
output_text = tokenizer.decode(translation[0], skip_special_tokens=True)
print("Translation:", output_text)
The model treats all NLP tasks as text-to-text problems. This code loads a T5 model, tokenizes an input text, and generates a translation from English to French.

from transformers import ViTFeatureExtractor, ViTForImageClassification
# Load a pre-trained Vision Transformer (ViT) model
model_name = "google/vit-base-patch16-224-in21k"
feature_extractor = ViTFeatureExtractor(model_name)
model = ViTForImageClassification.from_pretrained(model_name)
# Load and preprocess a medical image
from PIL import Image
image = Image.open("image.jpg")
inputs = feature_extractor(images=image, return_tensors="pt")
# Get predictions from the model
outputs = model(**inputs)
logits_per_image = outputs.logits
This code loads a ViT model, processes an image, and obtains predictions from the model, demonstrating its use in computer vision.
