Self-Reference in Large Language Models: The Introspection Threshold for Recursive Self-Improvement

arXiv:2607.04277v1 Announce Type: cross Abstract: The pursuit of self-evolving AI raises a critical question: when is autonomous self-improvement sustainable rather than degenerative? Drawing an analogy to von Neumann's complexity threshold for self-reproducing automata, we argue that sustainable recursive self-improvement in Large Language Models (LLMs) requires a functional analogue: introspection -- the system's capacity to simulate its own operations and target modifications. Grounded in Kleene's Second Recursion Theorem, we demonstrate the theoretical existence of such introspective progr

Why this matters
Why now

The paper provides a theoretical framework for self-improving AI at a time when LLM capabilities are rapidly advancing, raising practical questions about autonomous evolution.

Why it’s important

This research outlines a critical threshold for sustainable AI self-improvement, moving the discussion beyond speculative dangers and towards defining necessary conditions for safe and beneficial recursive development.

What changes

The concept of an 'introspection threshold' provides a new lens for evaluating AI development paths, distinguishing between sustainable and degenerative self-improvement cycles.
