The End of General Intelligence, The Start of Specialized Agents
After general large models like GPT-4 solved 80% of common sense tasks, the remaining 20%—tasks in the "deep water" of vertical domains such as law, medicine, and precision manufacturing—have become the true business explosion points for AaaS (Agent-as-a-Service).
The core of vertical domain AaaS is no longer pure computational competition but the deep integration of "industry-specific protocols."
Why Can’t General Agents Replace Vertical Agents?
- Compliance and Responsibility Constraints: In medical diagnosis or financial auditing, every operation by an Agent must comply with strict industry regulations. General models lack these "compliance neurons."
- Private Knowledge Barriers: Since the core Know-how in an industry is often hidden in non-public internal databases, vertical Agents can build extremely high competitive barriers through RAG (Retrieval-Augmented Generation) or proprietary fine-tuning.
- Long-process Automation: General Agents are good at conversation, while vertical Agents focus on "execution." For example, a legal Agent needs to be able to independently complete case filing, retrieval, document generation, and eventually interface with court APIs.
Blue Ocean Market: From Software Suppliers to "Outcome Suppliers"
Future vertical domain players will no longer sell management systems but "virtual employees." A business owner only needs to subscribe to a "senior tax Agent" in AIOS to dispense with an entire financial accounting team. This leap from SaaS to AaaS will completely reshape the labor structure of various industries.
