Microsoft Foundry's Production-Agent Release: A Solution Architect's Read
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). So it’s GA — but GA of what, exactly, and what should an enterprise architect actually do with it? This is the take, not a feature recap: the pro, the con, and where I’d draw the line.
