Scaling LLM Test-Time Compute Optimally Can Be More Effective than Scaling Model Parameters

This paper explores an alternative to the conventional approach of scaling large language models (LLMs) by increasing the number of parameters. Instead, the authors demonstrate that optimizing the compute resources allocated during test time can yield superior results in certain contexts. By intelligently allocating computational power, the study shows that performance can be enhanced without the exponential increase in resources typically required for larger models.

Key Findings:

• Research Question: Can optimizing test-time computation be more effective than simply increasing model parameters?
• Methodology: The study employs a variety of test-time compute optimization techniques, comparing their effectiveness across different tasks.
• Significant Findings: Targeted compute optimization can outperform traditional model scaling, particularly in tasks requiring real-time processing.
• Implications: This approach offers a cost-effective alternative for deploying high-performance LLMs, especially in environments with limited computational resources.
