xAI has launched Grok 4.5, its newest frontier AI model designed primarily for coding, software engineering, and long-running agentic workflows. The company says the model delivers improved reasoning, stronger performance on engineering and knowledge work, and competitive speed and pricing for enterprise deployments.
Grok 4.5 is positioned as a business-focused model rather than a consumer chatbot and was trained with additional coding data following xAI's acquisition of Cursor.
Elon Musk described the model as "Opus-class" while emphasizing its efficiency and cost advantages. Grok 4.5 is available through the xAI API and is aimed at production AI applications.
