xAI Launches Grok 4.5 With Deep Agentic and Code Execution Capabilities, Raising Enterprise Governance Stakes

xAI launched Grok 4.5 on July 8, 2026, positioning it as its most capable model for agentic tasks, software engineering, and long-horizon autonomous work. The model was co-trained with Cursor and runs reinforcement learning across hundreds of thousands of multi-step software engineering tasks, with agentic rollouts lasting many hours. Enterprises adopting Grok 4.5 for code generation or autonomous workflows face heightened obligations around agentic AI controls, AI-generated code license compliance, and third-party vendor governance.
