Categories of Inference-Time Scaling for Improved LLM Reasoning
Ahead of AI Sebastian Raschka, PhD
Inference-time scaling techniques allow language models to produce better answers by spending additional compute and time during inference rather than training, with approaches including chain-of-thought prompting, self-consistency, and search over solution paths. The author's experimental work with these methods improved a base model from 15 percent to 52 percent accuracy, demonstrating practical impact when hyperparameter tuning was applied across thousands of runs. These training-free techniques are now widely adopted by major LLM providers and represent a distinct alternative to improving models through additional training resources.
