马斯克的好兄弟，卡帕西又双叒出新指南，GPT-5 Pro是AI编程最后防线

Core Insights - The article discusses the evolving landscape of AI-assisted programming, emphasizing the shift in value from writing code to deleting it in a low-cost code generation environment [1][19] - Andrej Karpathy shares his experiences and methods for maximizing AI's assistance in programming, highlighting the importance of integrating multiple tools for different tasks [2][3] Tool Usage Philosophy - The philosophy of using tools is centered around the idea that tools should serve people, advocating for a combination of various workflows rather than relying on a single "perfect" tool [3] - Different tools excel at different levels of tasks, with tools like Claude Code and Codex being suitable for larger, less complex tasks, while Tab completion requires initial human input [3] Cursor (Tab Auto-Completion) - Karpathy indicates that Tab auto-completion is the primary method used in daily work, accounting for approximately 75% of his coding activities [4] - Writing code blocks or comments in the correct position can effectively communicate task specifications to AI [6] Auxiliary Tools (Claude Code / Codex) - Karpathy notes that while tools like Claude Code and Codex can generate code, they often lack "taste" in coding style, producing overly defensive or complex code [9] - These tools are particularly useful for tasks in unfamiliar areas, such as Rust or SQL, where they can generate extensive code quickly for debugging purposes [9][14] - The concept of the "post-scarcity era" of code is introduced, where the ability to create and discard vast amounts of customized code diminishes the perceived value of code itself [9][19] GPT-5 Pro: The Final Line of Defense - GPT-5 Pro is described as the ultimate tool for addressing the most challenging bugs that other tools cannot resolve, demonstrating its capability to identify subtle issues [14] - It can also assist in optimizing code abstraction and providing high-quality resources for specific topics [14] Characteristics of the Post-Scarcity Era of Code - The programming field is seen as being radically transformed by various paradigms and tools, leading to a sense of urgency to keep up with technological advancements [15] - The article highlights the potential for exploratory and experimental programming due to the lowered barriers to writing code [19]
