Why the Future of AI Is Not One Giant Model But Millions of Specialized Ones

The trend is shifting from monolithic general-purpose models to specialized small models for specific tasks. Smaller models are cheaper, faster, more private, and often better at their specific task than general models. Examples: medical diagnosis models, legal research models, code review models, customer support models. The infrastructure layer (fine-tuning, deployment, orchestration) for managing millions of specialized models is emerging as a major opportunity. This is the 'long tail' of AI — not every use case needs GPT-4; most need a 7B parameter model fine-tuned for their specific domain.
