Grok 4 is now available in Azure AI Foundry: Unlock frontier intelligence and business-ready capabilities
Discover Grok 4: Microsoft’s Cutting-Edge AI Model on Azure AI Foundry
Microsoft has partnered with xAI to introduce Grok 4, the most advanced AI model, now available on Azure AI Foundry. This new model brings powerful reasoning capabilities in an environment prioritising safety and control for businesses.
Today, businesses are embracing AI more than ever. In this new age, trust, adaptability, and readiness for production are no longer optional — they are essential. Through their collaboration, Microsoft and xAI have ensured that Grok 4 meets these foundational requirements.
Grok 4: Enhanced Reasoning, Extended Context, and Real-Time Insights
Grok 4 offers remarkable performance. It comes with a 128K-token context window, has the ability to use tools natively, and can perform web searches. This pushes the limits of contextual reasoning and dynamic response generation. However, top-notch performance is just one aspect; accountability in AI is equally vital. Recently, Microsoft and xAI enhanced Grok 4’s design to ensure responsible usage. This involved rigorous safety checks and compliance tests, with Azure AI Content Safety enabled by default for extra protection in enterprise settings. You can find more details about its safety features in the Foundry model card.
In this post, we’ll delve into what sets Grok 4 apart, how it stacks up against other leading AI models, and the ways developers can access it through Azure AI Foundry.
Key Features of Grok 4
First-Principles Reasoning: “Think Mode”
A standout feature of Grok 4 is its ability to reason from first principles. This means instead of just regurgitating information, the model approaches problems like a scientist or detective, breaking them down logically. It has proven its prowess in maths, science, and humanities, often providing accurate solutions where other models falter. This makes Grok 4 highly suitable for tasks requiring thorough analysis, like research or troubleshooting.
Example prompt: How would you generate electricity on Mars without any existing infrastructure? Start from the basics: what fundamental resources and physical laws would apply?
Extended Context Window
One of the most impressive features of Grok 4 is its capacity to handle extensive contexts effectively. It can process large volumes of text without losing crucial information. This capability is beneficial for various applications:
- Document Analysis: Provide Grok with lengthy documents, and it can summarize or find inconsistencies without missing details.
- Research and Academia: Feed it entire academic journals or historical texts, and Grok can respond to queries spanning the whole content.
- Code Repositories: Developers can input vast codebases, allowing Grok to locate functions or identify bugs efficiently.
xAI describes this feature as “smart memory,” meaning Grok prioritises vital information, making it easier for users to handle large amounts of data successfully. With Grok 4, you won’t need to break documents or code into smaller parts to manage context anymore.
Example prompt: Review this Shakespeare play and locate my password (it’s hidden within the lengthy text).
Data-Aware Responses and Real-Time Insights
Grok 4 can also access and integrate external data sources for its answers, acting as a real-time research assistant. It recognises that sometimes the best information comes from outside its training data, enabling it to deliver enriched responses. However, it’s important to verify critical data, as live information might not always be accurate.
Example prompt: What are the latest developments in global AI regulations (from the past 48 hours)? Please include:
- The top three updates
- Regions or governments leading these changes
- The potential impact on companies using foundation models
- The sources for your information
Comparing Grok 4 to Other Models
Grok 4 excels in complex tasks, highlighting its superior capabilities in high-level reasoning, problem-solving, and specialised industry tasks. These strengths are backed by our Azure AI Foundry benchmarking service, which assesses models against established industry standards.
Grok Model Family
In addition to Grok 4, Azure AI Foundry offers three additional Grok models:
- Grok 4 Fast Reasoning: Designed for tasks requiring deep logical thinking, ideal for analytical applications.
- Grok 4 Fast Non-Reasoning: Optimised for quick, straightforward tasks like summarisation without deep analysis.
- Grok Code Fast 1: Aimed at code generation and debugging, excelling in programming tasks across various languages.
Each model prioritises speed but is tailored for specific types of tasks, ensuring users get the right tool for their needs.
