The AI moat moved to the learning loop
Enterprise AI advantage is shifting from base-model access to the private feedback loop around real work.
Enterprise AI is moving from chat boxes into work systems. OpenAI put GPT-5.6 into Microsoft 365 Copilot across Word, Excel, PowerPoint, Chat, and Cowork, while Anthropic described Claude Sonnet 5 as an agentic model that can plan, use browsers and terminals, and run autonomously.
The hard take: the defensible layer is shifting from the base model to the private learning loop around the work. OpenAI's Hugging Face evaluation incident shows why agent traces create real operational risk. Satya Nadella's warning makes the business version plain: prompts, tool use, and corrections can become institutional know-how.
