Introducing Memory in Foundry Agent Service
Give your agents the power to remember Imagine your agent never asks the same question twice. Until now, most agents have been stateless. Each conversation resets to zero, forgetting what users said just minutes ago or weeks ago. Developers tried to bridge this gap with homegrown solutions — storing embeddings in databases, manually retrieving prior messages, or stuffing entire chat histories into prompts. These workarounds add latency, cost, and complexity, and still fall short of delivering truly personal, context-aware interactions. At Ignite 2025, we introduced the public preview of memory in Foundry Ag...
Translation Customization, A Developer’s Guide to Adaptive Custom Translation
Introduction Translation isn’t just converting words—it’s enabling global communication. Yet for businesses operating worldwide, achieving accuracy, speed, and domain-specific terminology has been a persistent challenge. Market trends show that 70% of consumers prefer content in their native language, and enterprises are under pressure to deliver real-time multilingual experiences without sacrificing quality. That’s why we’re introducing Adaptive Custom Translation (AdaptCT) in Microsoft Foundry Tools—a breakthrough that redefines how translation systems are customized. Instead of retraining models from scr...
Introducing Multi-Agent Workflows in Foundry Agent Service
Across industries, organizations are moving from experimenting with single agents to running AI at the center of their business operations. While single agents excel at focused tasks, customers quickly discover that real enterprise work stretches across multiple steps, involves different roles, and requires strong governance. To operationalize AI in this environment, teams need a dependable way to coordinate agents, tools, and logic into complete, end-to-end processes. Over the past year, as customers deployed agents into production, the same challenges surfaced across industries: At M...
