In this article, I'll share my thoughts on generative AI and how you can integrate state-of-the-art technology into your digital products.
What is Generative AI
Generative AI is a specific discipline in machine learning that allows computers to create new and exciting content automatically. With generative AI, the software can generate unique text, images, videos, or audio after being trained with relevant datasets. During the training, the AI algorithm learns specific patterns from the provided samples, remembers them, and uses the retained memories to create new outputs in a similar style.
At a glance, generative AI sounds simple, but it's not. Historically, works on generative AI date back to the 1950s, when researchers explored the foundational principles of artificial intelligence. Back then, they work with simple neural networks or rule-based models to mimic how humans think and make decisions.
Over the decades, data scientists have made tremendous progress, particularly in developing deep-learning neural networks. Some early models, Bayesian and Markov, are helpful in computer vision and robotics systems. But the birth of modern generative AI systems was rooted in 2014 when researchers unveiled the Generative Adversarial Network (GAN). And accelerated in 2017 with the introduction of Transformer architecture.
Today, generative AI tools like ChatGPT, Midjourney, Dall-E, and Bard harness the power of various neural networks, including diffusion networks, GAN, transformers, and variational autoencoders, to produce new, human-like content.
- A diffusion network trains with image samples by gradually adding noise to the source and backtracking the steps to generate realistic data representations.
- GAN is a deep-learning model that generates and checks its output to ensure they pass off as genuine data.
- Transformer is a neural network that allows a large language model to train with more input simultaneously. It introduces the attention concept, allowing the model to determine the importance of specific words in a sentence.
- Variational autoencoder derives and stores a probabilistic representation of the training samples, which it then uses as a reference to create original outputs.
A Glance at the Generative AI market
Financially, businesses have a huge incentive to embark on the generative AI train, whether as a provider or users. Studies revealed that the AI market is worth $11.3 billion globally. The figure is predicted to grow 35.6% over the next few years to $51.8 billion in 2028. Moreover, businesses that adopted AI in their workflow have demonstrated up to a 10% increase in revenue.
Even as I pen my thoughts, the generative AI space continues to evolve rapidly. New large language models are being released and trained with billions of parameters. Ordinary users are amazed by the capabilities of AI tools like MidJourney in generating vivid, realistic images. Likewise, marketers turn to linguistic models like GPT-4 to create engaging copies.
Here are some interesting insights on where the generative AI market is heading.
- The Covid pandemic has fueled the adoption of generative AI solutions, with major players like AWS, Google, and Microsoft taking the lead.
- Both diffusion and transformer neural networks continue to drive emerging AI systems.

Step-by-Step Guide to Building Generative AI Solution
Like it or not, generative AI is here to stay and will disrupt various industries in the near future. However, you can make the technology works in your favor by building your own AI solutions. At Uptech, we've helped companies develop AI capabilities from scratch, and here's how we do it.
Step 1: Understand the problem
As powerful as they are, generative AI models are only purposeful when solving the right problem. Therefore, we'll first need to determine the exact problems you're trying to solve. For example, a public speaking training company might need an AI system to turn ideas into speeches. This differs from a video upscaler, which uses a computer vision model to reproduce old videos in high-quality formats.
Pro tips: Create a realistic performance baseline, which helps benchmark the model's actual performance when deployed. It allows you to manage expectations and suggest further improvements down the line.
Step 2: Select the appropriate model, algorithms, and tools
Depending on the application's purpose, we must assemble the relevant software tools, foundational model, and tech stack. For example, OpenCV is a helpful framework if we're building an imaging system that extracts and classifies objects from camera feeds. Then, we use platforms like Jupyter Notebook to enable seamless collaborations amongst data scientists, machine learning engineers, and developers. It's also helpful to set up a pipeline that allows developers to train, fine-tune, test, and deploy the model collaboratively.
Step 3: Gather and process data for training
Downloadable AI models from sites like Hugging Face must be trained with business-specific datasets before they are helpful for your apps. Here, we'll need to collect training data from different sources and clean and label them to train the model. For example, we perform tokenization and part-of-speech tagging when preparing textual training datasets. At this stage, our annotators work closely with domain experts to produce high-quality training data.
Step 4: Create a proof of concept
Start with a proof of concept rather than integrating a fully-trained model into a solution. Use a simple model capable of demonstrating basic capabilities to get feedback from the target audience. Note that the model may not produce the desired performance, but it allows you to test the idea and gather feedback from real users.
Step 5: Train the model (optional)
Next, we thoroughly train the model. We feed the AI model with the annotated datasets to learn specific patterns, which it later uses to solve business problems. Generative AI models use self-supervised and semi-supervised learning methods to train. Human involvement is essential to fine-tune and align the model's scope, accuracy, and consistency with the business objective. For that, we evaluate the model's performance with recall, F1 score, and other metrics.
However, this is a very expensive step. If you can apply existing models with minimal fine-tuning — it's usually a preferable approach.
Step 6: Integrate it into the application
Once we're satisfied with the model's performance, we apply the AI model to the application. This involves hours of coding, integration, and testing various app functions in different environments. When building the application, we consider scalability, data security, and error handling. Understandably, generative AI systems require immense computing power, and we might recommend shifting to GPU or TPU-based machines.
Step 7: Testing & adjusting parameters
A deep learning model consists of many hyperparameters, which impact its performance. For example, the number of layers, hidden unit, and dropout rate may cause overfitting or underfitting issues when misconfigured. Therefore, we run rigorous tests to ensure the model performs optimally. If needed, we apply hyperparameters optimization techniques such as random search and grid search to obtain the best performance.
Step 8: Publish
We then deploy the AI application on the public cloud or on-premise infrastructure. We practice DevOps culture and have a robust CI/CD pipeline to ensure you always have a production-ready build.
Step 9: Monitor & improve
Our team continues to provide post-release support and evaluate the model's performance in real-life use cases. We look for bottlenecks and instances where the model fails to analyze or produce relevant outputs with real-world data. Then, we run further tests, refine the model and revise the application. At the same time, our team studies user feedback to ensure the app has a good product-market fit.
