Nearly a couple of years back - as I saw ChatGPT - just like everyone else who had been in the AI industry for the last decade, it was super clear that it was a turning point.

To be sure, from within the industry, from GPT-2 onward, it was clear that something massive was happening, as for the first time (even if at the time the AI still generated a lot of non-sense), the paradigm was changing, as the output wasn’t any longer stitching together of existing phrases, from a text the AI had somehow found.

But it generated it independently, unsupervised, by “making sense” of the underlying text. That was mind-blowing!

When ChatGPT came out, it was only the confirmation that the underlying model (GPT-3) with a new technique (InstructGPT) could be a game changer.

It's nearly two years after the fact, and we've reached a point where tools like NotebookLM are so impressive that it’s hard to imagine what’s coming next!

Indeed, the AI-generated this whole podcast episode after feeding it into our book AI Business Models!

Summary of the AI Theory Based on Layers, Hardware, Software, and Business Models

The AI Business Models book offers a glimpse into the evolving landscape of Artificial Intelligence (AI), highlighting key layers, technological advancements, and shifting business paradigms.

Layers of the AI Ecosystem:

These can be broadly categorized as:

• Infrastructure Layer: This encompasses the hardware and software foundations, with AI Supercomputers and GPUs playing a pivotal role in providing the computational power needed for training Large Language Models (LLMs).
• Model Layer: This layer focuses on the development and training of AI models like LLMs, utilizing techniques like pre-training on massive datasets and fine-tuning for specific tasks. Generative AI models, capable of creating new content, represent a significant advancement in this layer.
• Applications Layer: This layer comprises AI-powered applications and services that leverage the capabilities of underlying models. The AI Business Models book mentions various business models for companies operating in this layer, including ad-based, subscription-based, and consumption-based models.

New Hardware and Software:

• Hardware: The AI Business Models book emphasizes the critical role of GPUs in accelerating AI workloads. Unlike CPUs designed for sequential processing, GPUs excel at parallel processing, making them ideal for handling the massive datasets and complex computations involved in AI training. AI Supercomputers, equipped with numerous GPUs, provide the necessary computational power to develop and train LLMs.
• Software: The AI Business Models book highlights advancements in AI model architectures, particularly the Transformer Architecture. This architecture, leveraging "attention mechanisms," has revolutionized Natural Language Processing (NLP) tasks, enabling significant improvements in language understanding and generation.

New Business Model Paradigm:

The AI Business Models book touches upon the evolution of AI business models, though they don't provide a comprehensive historical analysis. However, they do highlight the "Reverse Kronos Effect", where startups leverage new technologies and agile practices to disrupt established industries. This effect is exemplified by Google's dominance in the search and advertising market, surpassing previous giants like AOL.

The AI Business Models book also mentions various business models for AI-powered applications, including ad-based, subscription-based, and consumption-based models. This suggests a shift towards more diverse monetization strategies in the AI Applications Layer.

Expected Developments:

The AI Business Models book hints at potential future directions:

• Multimodality: "Multimodality" is a key development in AI, enabling models to process and integrate diverse data types like text, images, audio, and video. This suggests a future where AI applications offer richer and more versatile experiences beyond text-based interactions.
• Emergence: The concept of "emergence" is mentioned in the context of AI. The phenomenon where complex behaviors and capabilities arise unexpectedly from the interaction of simpler components in AI systems. This suggests that future AI models might exhibit capabilities that go beyond their initial design, potentially leading to unforeseen breakthroughs and challenges.
