Microsoft Azure launches Anthropic Claude models powered by NVIDIA GB300 chips

NVIDIA and Microsoft team up to bring Anthropic's Claude models to Microsoft Foundry, powered by GB300 Blackwell Ultra superchips. The service runs on Azure cloud, starting with Claude Opus 4.8 and Claude Haiku 4.5.

It uses NVIDIA GB300 NVL72 racks with Quantum-X800 InfiniBand connections, supporting features like prompt caching and extended thinking. This works for coding, agent tasks, and complex reasoning. The models are fully integrated into Azure, and NVIDIA adds agent skills and a secure agent workspace design.
