Microsoft Developer (Build) · Jun 04, 2026 · Product Launches

Anthropic's Claude models, including newly released Opus 4.8, are available in Microsoft Foundry for agentic coding.

“We've pretty well solved coding when you look at it from this metric's perspective.”

Anthropic's Carolyn Matthews announced at Microsoft Build that Claude models—including the week-old Opus 4.8—are available in Microsoft Foundry for agentic coding, citing SWE-bench verified gains from 49 to 87.6 and agent sessions running up to 14.5 hours. This matters because it signals coding benchmark saturation and the shift toward long-running autonomous agents delivered through enterprise-governed Microsoft infrastructure.
