Grok 4 launches on Azure with advanced reasoning features
Azure has integrated safety features and compliance checks into Grok 4’s deployment.
Microsoft has announced that Grok 4, the latest large language model from Elon Musk’s xAI, is now available in Azure AI Foundry. The collaboration aims to deliver frontier-level reasoning capabilities with enterprise-grade safety and control.
Grok 4 features a 128,000-token context window, integrated web search, and native tool use. According to Microsoft, it excels at first-principles reasoning, handling complex tasks in science, maths, and logic. The model was trained on xAI’s Colossus supercomputer.
Azure says the model can analyse long documents, code repositories, and academic texts simultaneously, reducing the need to split inputs. It also incorporates external data for real-time responses, though Microsoft cautions that outputs should be verified against reliable sources.
The platform includes Azure AI Content Safety by default, and Microsoft stresses responsible use with ongoing monitoring. Pricing starts at $5.5 per million input tokens and $27.5 per million output tokens.
