Grok 4.2 is xAI’s latest large language model, built for strong reasoning, multimodal understanding, and enterprise use. It improves instruction following, honesty, and calibration over earlier Grok versions, while supporting both single‑agent and multi‑agxAI
xAIDirect from Azure
Version: 1
Direct from Azure models are a select portfolio curated for their market-differentiated capabilities:
- Secure and managed by Microsoft: Purchase and manage models directly through Azure with a single license, consistent support, and no third-party dependencies, backed by Azure's enterprise-grade infrastructure.
- Streamlined operations: Benefit from unified billing, governance, and seamless PTU portability across models hosted on Azure - all part of Microsoft Foundry.
- Future-ready flexibility: Access the latest models as they become available, and easily test, deploy, or switch between them within Microsoft Foundry; reducing integration effort.
- Cost control and optimization: Scale on demand with pay-as-you-go flexibility or reserve PTUs for predictable performance and savings.
About this model
Grok 4.2 is xAI’s latest large language model, built for strong reasoning, multimodal understanding, and enterprise use. It improves instruction following, honesty, and calibration over earlier Grok versions, while supporting both single‑agent and multi‑agent workflows. Designed as a general‑purpose, truth‑seeking assistant, Grok 4.2 is well suited for research, analysis, coding, and complex professional tasks when deployed with appropriate guardrails.

Safety techniques
Because models developed by xAI push the frontier of AI capabilities, xAI seeks to mitigate their risks through both evaluating model behaviors and implementing safeguards. Details about the evaluation and mitigation for top RAI risks are included in the xAI Grok 4.20 Reasoning model card.Safety evaluations
Microsoft's safety and responsible AI evaluations found Grok-4.20 Reasoning to be less safe than other models evaluated and offered through Azure Direct. In particular, the review found that the model brings (i) higher risks of producing potentially harmful content (e.g., content including hate and unfairness, sexual, violent, and glorification of self-harm) and (ii) higher risks of successful jailbreak attacks. Grok-4.20 Reasoning benchmarks and system evaluations are detailed in the xAI Grok 4.20 Reasoning model card. We have also made safety benchmarks available for this model in the model card benchmark tab and the tradeoff chart, which illustrates the significantly higher jailbreak success rates on Grok-4.20 Reasoning compared to other models.Known limitations and considerations
We require that customers use both system safety messages and Azure AI Content Safety (AACS) service to manage model behavior and comply with the Microsoft Enterprise AI Services Code of Conduct, but note that integration of these required safeguards will probably not mitigate all the risks. Given Microsoft's safety and responsible AI evaluation found Grok-4.20 Reasoning to be less safe than other models offered through Azure Direct (see "Safety evaluations" section above), there may be categories of harm this model can produce that are not covered by Azure AI Content Safety evaluation and mitigations. Therefore, customers should conduct their own evaluations according to their intended use cases and implement appropriate mitigations before deploying Grok-4.20 Reasoning in production systems.Acceptable use policy
Review the xAI model card for additional information on system evaluations, expected behavior, and safety systems. Customers are required to use both system safety messages and Azure AI Content Safety (AACS) service to manage model behavior and comply with the Microsoft Enterprise AI Services Code of Conduct. See the "Out of scope use cases" section for scenarios where we do not recommend deploying Grok-4.20 Reasoning.Key model capabilities
Grok 4.2 offers advanced reasoning and multimodal capabilities, supporting both text and image inputs for complex analytical, research, and coding tasks. It is designed to follow instructions more reliably, reason step‑by‑step, and operate in either single‑agent or multi‑agent configurations, enabling flexible workflows for professional and enterprise scenarios. As a general‑purpose, truth‑seeking model, Grok 4.2 is intended to handle a wide range of everyday and specialized tasks when deployed with appropriate oversight and safeguards.Quick facts
