Abstract: We are currently in a “Cambrian explosion” period of rapid artificial intelligence (AI) advancement, characterized by continuous improvements in large model capabilities, parameter scale, context length, tool utilization, and multimodal understanding, with benchmark scores being constantly refreshed. However, technological breakthroughs are not automatically translated into product success. The impressive demonstrations, witnessed in laboratory settings and the outstanding rankings on leaderboards, remain distinct from whether AI can become a reliable, efficient, and indispensable partner in developers’ daily workflows. A powerful foundational code model does not equate to a successful intelligent development tool. Particularly, once model capabilities reach the usability threshold for specific scenarios, engineering considerations, scenario adaptation, workflow integration, and clear responsibility boundaries often emerge as equally critical constraints. Achieving product success requires an expedition that begins with technology, matures through engineering, and ultimately culminates in user experience.
