On January 19, 2026, ByteDance's AI Agent platform, 'Kouzi,' officially declared its 2.0 brand upgrade. This upgrade encompasses the integration of four pivotal capabilities: Agent Skill, Agent Plan, Agent Coding, and Agent Office.

Agent Skills are a collection of top-tier practices and tools tailored for specific scenarios. They offer specialized skill modules that can be seamlessly applied to address particular needs. For instance, in a customer service scenario, an Agent Skill module could provide pre-defined responses and strategies for handling common customer inquiries, enhancing efficiency and consistency.

Agent Plan, on the other hand, excels in complex goal decomposition. It breaks down large, intricate objectives into smaller, manageable steps and continuously tracks the progress towards achieving these goals. Imagine planning a large-scale marketing campaign; Agent Plan can dissect the campaign into tasks like market research, content creation, and promotion scheduling, and then monitor the completion of each task.

Agent Office demonstrates a profound understanding of workplace scenarios. It is adept at handling a wide range of office tasks, from scheduling meetings and managing emails to organizing documents. It can act as a virtual assistant, streamlining daily office operations and boosting productivity.

Agent Coding plays a crucial role in supporting the development of agents and workflows. It enables the creation and customization of agents and workflows through coding. Moreover, it allows for self-iteration through multi-round dialogues. For example, developers can use Agent Coding to build an agent that learns from user feedback in each interaction and improves its performance over time.
