Grok 4.6 — SpaceXAI’s latest frontier model — just landed in public preview in Microsoft Foundry as an Azure Direct Model. The headline isn’t “another big model dropped.” It’s that Grok 4.6 is built specifically for long-horizon, agentic work: planning across many steps, calling tools reliably, recovering when something goes wrong, and handing you a finished work product instead of a half-baked fragment you have to stitch together yourself.
That’s a meaningfully different design target than “answer this one prompt well.” And it’s exactly the kind of thing that matters once you move past demos and start building agents that actually have to survive contact with real workloads.
As always: no Python required, no notebook required. Just Microsoft.Extensions.AI and dotnet run.
