New Theory Maps When Extra Test-Time Reasoning Actually Helps LLMs
A sampling-complexity analysis of generate-critique-revise loops formalizes the conditions under which in-context search improves answers rather than only consuming inference compute.
A theoretical paper, When Does In-Context Search Help?, takes on a question that the test-time-compute era has mostly answered by experiment. Extended reasoning, in which a model repeatedly generates, critiques, and revises its own attempts…

Test-Time Compute Becomes a Managed Budget
As reasoning models make inference-time search a primary capability lever, allocating test-time compute per task rather than uniformly becomes a recurring axis of both capability and cost optimization.
