Core Viewpoint - The article emphasizes the importance of "Context Engineering" as a systematic approach to optimize the input provided to Large Language Models (LLMs) for better output generation [3][11]. Summary by Sections Introduction to Context Engineering - The article highlights the recent popularity of "Context Engineering," with notable endorsements from figures like Andrej Karpathy and its trending status on platforms like Hacker News and Zhihu [1][2]. Understanding LLMs - LLMs should not be anthropomorphized; they are intelligent text generators without beliefs or intentions [4]. - LLMs function as general, uncertain functions that generate new text based on provided context [5][6][7]. - They are stateless, requiring all relevant background information with each input to maintain context [8]. Focus of Context Engineering - The focus is on optimizing input rather than altering the model itself, aiming to construct the most effective input text to guide the model's output [9]. Context Engineering vs. Prompt Engineering - Context Engineering is a more systematic approach compared to the previously popular "Prompt Engineering," which relied on finding a perfect command [10][11]. - The goal is to create an automated system that prepares comprehensive input for the model, rather than issuing isolated commands [13][17]. Core Elements of Context Engineering - Context Engineering involves building a "super input" toolbox, utilizing various techniques like Retrieval-Augmented Generation (RAG) and intelligent agents [15][19]. - The primary objective is to deliver the most effective information in the appropriate format at the right time to the model [16]. Practical Methodology - The process of using LLMs is likened to scientific experimentation, requiring systematic testing rather than guesswork [23]. - The methodology consists of two main steps: planning from the end goal backward and constructing from the beginning forward [24][25]. - The final output should be clearly defined, and the necessary input information must be identified to create a "raw material package" for the system [26]. Implementation Steps - The article outlines a rigorous process for building and testing the system, ensuring each component functions correctly before final assembly [30]. - Specific testing phases include verifying data interfaces, search functionality, and the assembly of final inputs [30]. Additional Resources - For more detailed practices, the article references Langchain's latest blog and video, which cover the mainstream methods of Context Engineering [29].
