Anthropic warns AI could soon help build its own successors

AI development is moving so rapidly that soon it will be able to advance itself without human involvement, per a new blog post from Anthropic.

Why it matters: "Recursive self-improvement," a process in which AI systems build, test and improve themselves, is a phenomenon which may come sooner than expected, Anthropic says its research shows.

Driving the news: Anthropic warns that AI is no longer just changing how people work, it's also beginning to change how AI itself gets built.

• New data from the company suggests that frontier models have accelerated coding, debugging and research.
• That is likely to create a feedback loop in which AI systems create even more sophisticated successors.

What they're saying: "We've always found that the best thing to do is to socialize the concept and basically give people a sense of what's coming," Anthropic's Jack Clark said in an interview with Axios.

• "The big story here is what we see are indications that, contrary to some popular opinion, AI progress is going to speed up in coming years rather than stay the same, or diminish."
• Clark said that it is especially promising for progress in science and medicine, but requires planning for its impact on AI itself and how it fits into existing work in those industries.

The company wants lawmakers in the loop on the topic before they start hearing about "recursive self improvement" in earnest, Clark said.

• "As organizations, and eventually probably as societies, we need to figure out the tools to validate and verify that the stuff being done by these AI systems is correct and is aligned with human intentions aligned with a thriving society," he said.

The big picture: Improvements in the Claude chatbot have turned into improvements in AI coding agents, which have turned into improvement in autonomous agents.

• Recursive self improvement is the likely next step, Clark argues in the post: "In the near future, AI systems could become capable enough to autonomously design, build and train more capable successors on their own."
• "If that happens, each new version of Claude could be built by the version before it, without human involvement."

OpenAI has published its own concerns and findings about "recursive self-improvement" as well. In a December 2025 blog it described it as a potentially dangerous phenomenon if researchers don't share information about it.

What we're watching: Anthropic plans to engage lawmakers about recursive self-improvement in the coming months.

The bottom line: AI that builds itself is on the horizon, and AI labs are saying they're not sure what the impact on the world will be — but they feel a need to warn everyone about it.
