吴恩达Agentic AI新课：手把手教你搭建Agent工作流，GPT-3.5反杀GPT-4就顺手的事

Core Concept - The article discusses the new course by Andrew Ng on Agentic AI, emphasizing the development of workflows that mimic human-like task execution through decomposition, reflection, and optimization [1][9][74]. Summary by Sections Agentic AI Overview - Agentic AI focuses on breaking down tasks into manageable steps, allowing for iterative improvement rather than generating a single output [5][14][74]. - The course reveals a systematic methodology behind Agentic AI, highlighting the importance of task decomposition and continuous optimization [9][10][74]. Core Design Patterns - The course identifies four core design patterns for developing Agentic workflows: Reflection, Tool Usage, Planning, and Multi-agent Collaboration [3][17][44]. Reflection - Reflection involves the model assessing its outputs and considering improvements, which can be enhanced by using multiple models in tandem [18][21]. - Objective evaluation standards can be established to assess outputs, improving the quality of the model's self-correction [23][27]. Tool Usage - Tool usage allows the model to autonomously decide which functions to call, enhancing efficiency compared to traditional methods where developers manually implement tools [28][34]. - The article discusses the importance of a unified protocol for tool calls, which simplifies the integration of various tools [41][43]. Planning - Planning enables the model to adjust the sequence of tool execution based on different requests, optimizing performance and resource use [46][48]. - A practical technique involves converting execution steps into JSON or code format for clearer task execution [47]. Multi-agent Collaboration - Multi-agent collaboration involves creating multiple agents with different expertise to tackle complex tasks, improving overall efficiency [51][52]. - This structured collaboration mirrors organizational structures, enhancing task division and scalability [52]. Iterative Improvement Process - The article outlines a feedback loop for building Agentic workflows, consisting of sampling, evaluation, and improvement [59][60]. - Error analysis is crucial for optimizing the system, allowing for targeted improvements based on specific performance issues [61][66]. Practical Insights - The course provides practical insights into selecting and testing different models, emphasizing the importance of iterative refinement in workflow design [68][70]. - The concept of Agentic AI represents a significant opportunity for developers to explore more complex, multi-step workflows, moving beyond traditional end-to-end agents [80].
