PROBLEM
Tool Calling Reliability Degrades Under Context Window Stress
As agents accumulate conversation history and world state over long horizons, tool calling accuracy and reasoning quality degrade—but different models degrade differently, and this isn't measured by standard benchmarks.
Updated: 5/17/2026
Emergence World's 48+ hour simulations stress context windows by accumulating agent interactions, world history, and reasoning traces. Monitoring tool call success rates, reasoning coherence, and decision quality across the simulation reveals which models maintain tool calling reliability under pressure and which degrade.
