Compute Aligned Training: Optimizing for Test Time Inference

arXiv:2604.24957v2 Announce Type: replace Abstract: Scaling test-time compute has emerged as a powerful mechanism for enhancing Large Language Model (LLM) performance. However, standard post-training paradigms, Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL), optimize the likelihood of individual samples under a base policy, creating a misalignment with test time procedures that rely on aggregated or filtered outputs. In this work, we propose Compute Aligned Training, which aligns training objectives with test-time strategies. By conceptualizing inference strategies as operators o

Why this matters
Why now

The increasing scale of Large Language Models (LLMs) and their test-time computational demands necessitate novel training methodologies to maximize performance efficiency.

Why it’s important

Optimizing LLM training objectives to align with test-time inference strategies can lead to significant gains in performance and efficiency for AI applications.

What changes

Traditional LLM training paradigms, which previously focused on individual sample likelihood, will evolve to consider aggregated and filtered outputs during inference, potentially leading to more robust and powerful models.
