Grok 4 Now Available in Azure AI Foundry: Advanced Reasoning and Business-Ready AI

Microsoft, in collaboration with xAI, has introduced Grok 4—their most advanced AI model—to Azure AI Foundry. This enables organizations to leverage powerful, business-ready AI with strong focus on safety, reasoning, and enterprise requirements.

Key Features of Grok 4

  • First-Principles Reasoning: Grok 4 is built for step-by-step logical problem solving, making it ideal for research, tutoring, and troubleshooting workflows where logical consistency is critical.
  • 128K-token Context Window: Capable of ingesting and reasoning over large documents, codebases, or research papers without losing track of details, making it suitable for document analysis, academic research, and large-scale code reviews.
  • Data-Aware and Real-Time Insights: Integrates external data sources and trending information, so responses can reflect current data and dynamic research, useful for up-to-date analyses and reporting.
  • Architecture: Grok 4 uses reinforcement learning (RL), multi-agent approaches, and a focus on reasoning over rote memorization. Trained on xAI’s Colossus supercomputer, it marks a substantial shift in model capability and scale from Grok 3.

Safety and Enterprise Readiness

  • Enterprise Controls: Azure AI Foundry emphasizes business-grade safety. Azure AI Content Safety is enabled by default for responsible deployment, with Grok 4 undergoing comprehensive safety tests and compliance checks.
  • Responsible Deployment: The article emphasizes pairing Azure’s guardrails with custom domain checks, ongoing output monitoring, and transparent safety score disclosures.

Model Variants in Azure AI Foundry

  1. Grok 4: Full-featured for advanced reasoning and intelligence tasks.
  2. Grok 4 Fast Reasoning: Optimized for high-speed logical inference and analytics.
  3. Grok 4 Fast Non-Reasoning: Focused on efficiency for summarization and classification tasks.
  4. Grok Code Fast 1: Built for code generation, debugging, and developer workflows across multiple languages.

Pricing Overview

  • Grok 4 Global Standard: Input – $5.5/1M tokens, Output – $27.5/1M tokens (includes Content Safety)

Developer Use Cases

  • Complex research and analysis – stepwise logical answers for scientific, business, or academic problems
  • Large-scale document or code analysis – ingest and summarize or interrogate entire books, research articles, or code repositories
  • Real-time data synthesis – drawing on up-to-date external information within model responses
  • Enterprise deployment – safe, controllable AI integrations suitable for business workflows
