An AI just 'gave birth' to itself by rewriting its own code from scratch based on nothing but a one-sentence bio.

The Takeaway
In a classic 'meta' move, researchers gave an AI a 926-word description of what it was and how it should work. The AI then successfully built a functional version of itself from that text alone, proving that AI models can now bootstrap their own existence without human-written code being the primary artifact.
From the abstract
A coding agent can bootstrap itself. Starting from a 926-word specification and a first implementation produced by an existing agent (Claude Code), a newly generated agent re-implements the same specification correctly from scratch. This reproduces, in the domain of AI coding agents, the classical bootstrap sequence known from compiler construction, and instantiates the meta-circular property known from Lisp. The result carries a practical implication: the specification, not the implementation,
