Andrej Karpathy: From Vibe Coding to Agentic Engineering — Summary & Key Points
TL;DR
Andrej Karpathy argues we are shifting from 'vibe coding' to 'agentic engineering' as AI evolves into Software 3.0, where prompting replaces explicit coding. He explains that current models are 'jagged'—excellent at verifiable tasks like code but failing at non-verifiable logic—requiring humans to act as directors with taste rather than coders.

The argument
The Software 3.0 Paradigm
Software 3.0 shifts programming from writing explicit code to prompting an LLM interpreter using the context window as a lever. This is evident in OpenCLAW installation, which now requires only a copy-paste of text for an agent to handle complex platform compatibility, and MenuGen, where a simple prompt to Gemini with Nanobanana overlays renders a menu image better than a custom app.
Jagged Intelligence and Verifiability
Current models exhibit 'jagged' capabilities, peaking in verifiable domains like math and code due to RL training but failing in non-verifiable domains like logic. An example is Opus 4.7 simultaneously refactoring a 100,000-line codebase and incorrectly telling a user to walk 50 meters to a car wash, indicating models are 'ghosts' shaped by data distribution rather than intrinsic intelligence.
From Vibe Coding to Agentic Engineering
Vibe coding raises the floor for everyone by allowing anyone to build, while agentic engineering preserves the quality bar of professional software by treating agents as interns that require oversight. The discipline involves designing specs and managing agents to go faster without introducing vulnerabilities, requiring humans to provide taste and judgment rather than syntax.
The Future of Infrastructure and Education
The world must move toward agent-native infrastructure where systems are described by sensors and actuators for LLMs to interact with. Regarding education, Karpathy notes that while AI can outsource thinking, it cannot replace understanding, making human oversight the bottleneck for directing agents.
