Intrinsic Stability Limits of Autoregressive Reasoning: Structural Consequences for Long-Horizon Execution
#LLM #Autoregressive Reasoning #arXiv #Long-horizon tasks #AI stability #Deep Learning #Structural Breakdown
📌 Key Takeaways
- LLMs face a systematic breakdown in performance during long-duration or 'long-horizon' reasoning tasks.
- The research suggests that reasoning failure is an intrinsic structural issue rather than just a result of task complexity.
- Performance deterioration occurs even in linear, non-branching tasks, challenging existing theories of AI failure.
- Current autoregressive architectures may have mathematical stability limits that prevent reliable long-form execution.

arXiv:2602.06413v1 Announce Type: new Abstract: Large language models (LLMs) demonstrate remarkable reasoning capabilities, yet their performance often deteriorates sharply in long-horizon tasks, exhibiting systematic breakdown beyond certain scales. Conventional explanations primarily attribute this phenomenon to task complexity, such as combinatorial search explosion or long-term credit assignment challenges. In this work, we argue that these explanations are incomplete: even in linear, unbra
