Grok 4.5 Released: xAI Merges Code, Agent, and Office Work into Flagship Model
xAI released Grok 4.5 in July 2026, available via API, Grok Build, Cursor, and Office plugins.
Grok 4.5 simultaneously enters coding agents, developer APIs, office documents, and third-party tools. Compared to single-model scores, this cross-entry deployment better indicates that xAI is building a unified execution layer.
Officially disclosed, the model is trained for software engineering and long-duration agent rollouts, offering configurable reasoning intensity, 500K context, and emphasizing token efficiency and fast inference serving.
Frontier model companies are further integrating training, models, agent runtime, and distribution products; the application layer needs to prove its proprietary processes, data, and complete delivery capabilities.
Enterprises should evaluate separately for coding, documentation, and research tasks, and should not omit permissions, data boundaries, and human review design due to a unified entry point.
Observe independent coding benchmarks, real success rates on Office tasks, EU availability, API stability, and total cost per completed task.
