Microsoft launches Copilot Harness in Foundry Agent Service for multi-model orchestration
What happened.Microsoft made its Copilot harness generally available in Foundry Agent Service, allowing developers to orchestrate multi-model autonomous agents across OpenAI, Anthropic, and open-source models.
Why it matters.Building custom agent execution harnesses forces engineering teams to maintain fragile scaffolding around context windows, tool retries, and session memory. Adopting a standardized managed harness allows teams to upgrade underlying frontier models instantly as price and intelligence frontiers advance.
