Test-Time Compute Matters: From LLMs to Search
May 7, 2025
Test-time compute has recently been popularised with LLMs (e.g. o1/o3, DeepSeek-R1 and other reasoning models) as its application has allowed LLMs to perform significantly better on complex reasoning problems (e.g. mathematics, reasoning). This article explores why it works, why it’s not new, and how it’s been employed across different AI paradigms.
