Generative AI is no longer the stuff of science fiction—today, it’s fast becoming the building block on which digital transformation in the modern era is based. From content generation to art composition and from customer service to automation, generative models are opening up new frontiers. Two of the most impactful technologies spearheading this revolution are GPT (Generative Pre-trained Transformers) and Diffusion Models.
As the demand for real-time content generation and smart automation grows, companies are actively looking to hire generative AI developers to onboard and collaborate with a freelancer generative AI engineer to drive adoption and innovation.
What is Generative AI?
Essentially, Generative AI is machine learning technology that has the ability to generate new data like that of human-produced content. From generating natural language to image creation, music writing, or even code for software, generative AI is trained on vast datasets and then employs the data to generate new outputs.
By 2025, 30% of large organizations’ outbound marketing messages will be synthetically generated, up from less than 2% in 2022, according to Gartner. This rapid growth reflects both the maturity as well as the market hunger for scalable generative solutions.
GPT Models: The Transformer Technology Behind Intelligent Text
The GPT models are transformer-based, a deep learning innovation that enables machines to grasp context within long sequences. OpenAI created the GPT models, now ubiquitous, and the models use billions—and in most cases, trillions—of parameters to decide on the next word in a sentence.
These models are trained on enormous datasets. For example, GPT-4, supposedly with 1.76 trillion parameters, is trained on all types of internet content, e.g., books, codebases, papers, etc. With these enormous sets of materials, the model gets to see subtle nuances, intent, and context.
GPT’s strength is its self-attention mechanism by which the model is able to assign relative weights to the importance of various words within a sequence. This enables fine-grained and very coherent output—whether generating a business report, writing computer code, or simulating human-like conversation.
In the current market, businesses increasingly employ generative AI developers who are skilled with transformer models to develop applications from smart chatbots and virtual assistants to dynamic content engines.
Uses of GPT in the Real World
- Content Automation: Companies are employing GPT to automate emails, product descriptions, and blogs.
- Customer Service: Virtual agents powered by GPT can answer thousands of questions in just one second with minimal human intervention.
- Code Generation: GitHub Copilot uses transformer-based models to assist developers in real time.
Up to 70% of business operations, as estimated by McKinsey, may be half-automated by generative AI, highlighting the need to utilize individuals such as a freelancer generative AI engineer or internal experts in an attempt to remain competitive.
Diffusion Models: Noise to Art
In contrast to the GPT models, which are text-focused, vision generation is where diffusion models excel. The models begin with clean noise and progressively denoise the data in a manner that they output structured and quality images. In fact, they just reverse a noising process to reconstruct or create new data.
One of the best-known examples is Stable Diffusion, which can generate photorealistic images from text inputs in just seconds. Indeed, on top-of-the-range GPUs, Stable Diffusion can generate a 512×512 image in a few seconds, and it is therefore a favorite among developers and designers for real-time applications.
Reverse diffusion is driven by optimized deep convolutional neural networks (CNNs) that are used to predict the noise at every step, progressively reconstructing noisy data into functional images.
Real-World Applications of Diffusion Models
- Marketing and Design: Companies like Adobe and Canva are implementing diffusion to allow marketers to produce at scale.
- Film and Animation: Studios use diffusion models for concept art, storyboarding, and visual effects.
- Product Prototyping: Text descriptions are rapidly converted into prototypes and mockups by designers.
As the technical and creative demands of these applications increase, companies are vying to hire generative AI developers who have a dual skill set of experience with image processing and model optimization, and they prefer to hire a freelancer generative AI engineer to accelerate pilots and MVPs.
