Why is Claude Code Anthropic’s testing ground for AI safety?

Many people regard Claude Code as a coding agent, but Boris Cherny gives a lower-level perspective: For Anthropic, coding is a natural scenario for studying AI safety.

Because code has feedback, constraints, and real-world interactions.

How the model will plan, call tools, fix errors, and deviate from the goal can only be seen when it is put into real tasks.

The meaning of Claude Code is not just to help programmers write code.

It is also a window into how the model enters the real world.
