According to CoinMeta, well-known AI commentator and New York University professor Gary Marcus stated that Claude Code represents the largest single advancement in the AI field since the emergence of LLM, although it is not AGI. Its core technology combines classical AI rather than relying solely on pure LLM or deep learning. Based on leaked source code, the Claude Code's print.ts kernel file contains 3,167 lines of code, 486 branching points, and a 12-layer nested if-then structure. The creator of Arc-AGI, Fran, pointed out that current high-performance AI agent is a complete system composed of "model + program," where the model is responsible for understanding, and the program controls the process and tool calls. He believes that in the future, the competition in AI will not just be about the strength of the model, but about the coordination of the entire agent system.
