The Illusion of Diminishing Returns: Measuring Long Horizon Execution in LLMs
arXivresearchpositiveSep 21, 2025

Short-task benchmarks create an illusion of diminishing returns in LLM scaling; marginal gains in single-step accuracy compound into exponential improvements in long-horizon task execution, with larger models demonstrating significantly better execution capability across extended task sequences.

Researchers from Cambridge and team show small models succeed briefly but fail quickly on extended multi-step tasks
arXivresearchneutralSep 15, 2025

Small language models appear to succeed on short tasks but fail rapidly on extended multi-step tasks due to execution errors and self-conditioning degradation, while scaling and sequential test-time compute significantly improve long-horizon task completion.
