The Deterministic Horizon: When Extended Reasoning Fails and Tool Delegation Becomes Necessary
Researchers establish fundamental information-theoretic limits on decoder-only transformer attention for state-tracking tasks, proving extended reasoning degrades performance beyond a 'Deterministic Horizon' of 19-31 steps. Tool delegation consistently outperforms neural chain-of-thought across 12 models (86-94% vs 24-42% accuracy), suggesting hybrid agentic systems require external tools rather than pure neural reasoning for complex deterministic tasks.
