What is Generative AI Architecture?

Generative AI is a subset of artificial intelligence which leverages advanced machine learning techniques that particularly comes with deep learning and enables models to produce original content. Generative AI comes with autonomous content creation, learning and mimicking patterns, and unleashing versatility. 

For instance, GAN (Generative Adversarial Network) is a generative AI architecture that comes with two neural networks called generator and discriminator which are trained through a competitive process. This network produces synthetic data samples which work similar to training data while discriminator is a network that helps to distinguish between real and synthetic data. Later these two networks produce realistic samples and offer convincing outputs. 

Few of the other examples include VAEs, transformers, and other autoregressive models that use the generative data. Make AI companion chatbot app like Replika to interact with users on your behalf by employing AI technology.

Layers of Generative AI Architecture

• Application layer

In this layer, the generative AI tech stack enables machines and humans to collaborate with each other seamlessly  by making AI models more accessible and easy to use. This can be classified into end-to-end applications using various models. Later, this end-to-end application uses generative AI models developed by companies based on domain expertise. While apps without proprietary models use open-source AI framework to build custom models using specific use cases. 

• Data platform and API management layer

To achieve better outcomes high-quality data is crucial in generative AI. While getting a proper state requires 80% of the development time which include data ingestion, quality check, cleaning, storage, and vectorization. Additionally, organizations follow strategies for both structured and unstructured data which is necessary to align with Gen AI strategy.

• LLMops and Prompt engineering layer

LLMops comes with technologies, tooling, and practices to adapt and deploy models with end-user applications. It comes with activities like choosing a functional model, adapting this model for specific use cases, elevating the model, deploying it, and monitoring its performance accordingly. Moreover, one can adapt to fine-tuning prompt engineering which requires data labeling, model training, and deployment to production. 

• Model layer and hub

In this layer the model includes machine learning foundation models, LLM foundation models, a model hub, and fine-tuned models. This model serves as a foundation model of generative AI which works as a backbone. Along with this, it comes with deep-learning models to create specific content types which can be adapted for carrying out various tasks. Later the foundation layer is used to train models for both public and private datasets. 

• Infrastructure layer

This is the model that includes cloud platforms and hardware which is responsible for training workloads. While the traditional computer hardware cannot handle the massive amount of data, generative AI comes in to handle large datasets and clusters of GPUs or TPUs using specialized accelerator chips. With this, most businesses prefer to build and run large AI models in the cloud which can easily access computational power along with managing the spending when required. 

Models of Generative AI Architecture

• Large language models

LLM works as mathematical models which represent patterns found in natural language use. It can generate text, answer questions, and hold conversation within a sentence. Essentially, this can build sentences which sound human. These large language models have a wide range of multidimensional word representation of how words can be used in context along with providing examples. Let’s say, GPT-3 does not work well with humans- like conversations while GPT-4 runs using the customized version as it has its own LLM model.  

• Text-to-image models

DALL-E 2 or Mid journey is a text-based model that creates images using a simple effective technique. This model is well-trained to generate labeled images, represented numerically projected into a latent space.
