Anthropic revealed that Claude writes 90% of the company's code

Anthropic revealed that its AI Claude writes over 90% of the code used in the company. Financial director Krishna Rao announced this, emphasizing the depth of the AI assistant's integration across all development stages. This is not just a figure — it's a signal of how a technology leader is reformatting processes around artificial intelligence.

Record-Breaking Integration Indicator

This result means that Claude is now not an auxiliary tool, but the primary code developer at the company. This is not about one-off helpers like autocomplete — the AI writes functions, tests, documentation, refactors existing code, suggests architectural improvements. Anthropic developers work in code review and architecture mode, not line-by-line coding mode.

This transition happened gradually, through years of experiments and optimization. At first, Claude helped with simple tasks; then it was trained on the company's style through examples; then it was integrated into CI/CD so that the AI generates code automatically based on tickets. Now developers create a ticket, outline the requirement in two sentences — and Claude generates the first draft of a PR. A person reviews, fixes moments that only humans notice (context, edge cases, performance), and merges. The process is accelerated 2-3 times.

Tech Race Declared

Google, Meta, Microsoft are also implementing AI in development. But they rarely disclose real metrics. Anthropic was the first to dare name a specific percentage — 90% — which automatically made it a leader in the hidden competition for automation. Other companies are either falling behind or afraid to disclose figures. For investors, this is a signal: Anthropic is not just talking about AI in programming, but has implemented it at scales that seemed unattainable a year ago.

An additional bonus is PR and talent attraction. Developers prefer companies where they can learn from AI rather than compete with it.

The advantages of this approach are obvious:

• Iteration speed increases — less time on mechanics, more time solving complex problems
• Code review focuses on logic and architecture, not syntax
• New developers adapt faster — Claude writes in the company's style
• Fewer bugs from copy-paste and carelessness — the AI is consistent

What This Means

AI programming has moved out of the experimental stage and entered a mode of industry reformatting. For developers, this means requalification: from syntax writer to system architect, API designer, code reviewer. The developer of the future is not one who writes more lines, but one who can formulate a task, verify a solution, and notice what the AI missed. For Anthropic, such dependence on Claude creates a risk — but they considered it worth the price for speed and the current advantage.
