Editor's Synopsis
Andrej Karpathy shares his experience with Claude coding over the past few weeks, noting a dramatic shift in his development workflow. He describes moving from roughly 80% manual coding with autocomplete and 20% agent-assisted coding in November to an inverted ratio of 80% agent coding with only 20% manual edits and touchups by January 2026.
The post reflects a broader trend among developers rapidly adopting LLM-powered coding agents as their capabilities have improved significantly. Karpathy's firsthand account underscores how quickly AI-assisted development is becoming the dominant workflow for experienced programmers, signaling a major shift in software engineering practices.
