Grok 4.6 is now on Microsoft Foundry

xAI said on 26 August 2026 that Grok 4.6 is now available on Microsoft Foundry.

The company calls Grok 4.6 its latest flagship, built for long-running agents and interactive and visual work. The post lists a 500k context window and configurable reasoning efforts: low, medium, high, and xhigh.

xAI said Foundry lets organizations evaluate Grok 4.6 against other frontier models, run workload-specific tests, deploy managed endpoints, and use enterprise security and governance controls. It pointed coding agents, engineering copilots, research assistants, and enterprise automation at the Foundry model catalog, and linked Microsoft’s announcement plus an integration guide.
