Algorithm Store

The artificial intelligence industry is undergoing a fundamental structural transformation. In 2023, the global AI market was valued at approximately $196 billion, with projections reaching $1.8 trillion by 2030 according to Grand View Research. However, the most significant shift is not in the size of the market, but in its architecture. We are witnessing the emergence of a two-tier AI economy: the foundation model layer, dominated by players like OpenAI, Anthropic, Google, and Meta with massive capital expenditures exceeding $100 billion combined; and the vertical application layer, where thousands of specialized models serve niche industry needs. This book is about the second tier—specifically, the infrastructure required to build, operate, and scale an algorithm marketplace. The "Algorithm Store" is not a hypothetical concept. It exists today in various forms: Hugging Face hosts over 500,000 models and serves as the de facto GitHub for machine learning; Replicate provides a marketplace of open-source models as API endpoints; CivitAI has built a thriving community around Stable Diffusion models with millions of monthly downloads; and Azure AI Studio, AWS SageMaker, and Google Vertex AI all offer model discovery and deployment capabilities.
