Agentic-Ai

A model can only generate text. The harness is the loop around it that calls tools, manages context, gates actions, and decides when to stop.

Satya Nadella just named something every architect should pin to the wall. Kenneth Arrow’s old information paradox said a seller can’t prove information’s worth without revealing it: disclose, and you’ve given it away. AI inverts it: now the buyer leaks. To get real value from a model you feed it your proprietary context, and the vendor learns more about you than you learn from it.

Microsoft’s Build 2026 announcement, Frontier models and production agents advancing Microsoft Foundry for the agentic era, reframes Foundry from a model catalog into a place you run production agents. The headline that makes it real: hosted agents in Foundry Agent Service are now generally available, and the catalog spans both OpenAI and Anthropic frontier models (1,900+ on Microsoft Learn, not the “11,000” some coverage repeats).

Every vendor selling software right now claims their product is “agentic.” I’ve seen chatbots with a system prompt called an agent. I’ve seen a scheduled Python script described as autonomous AI. I’ve also shipped actual agents to production, at an insurance company, handling FNOL triage, policy lookup, and claims routing. The gap between what gets marketed as an agent and what you’d actually build in production is wide, and it’s expensive to get wrong.
