Inference-time Compute 缩放定律

🎯Core Definition

Inference-Time Compute Scaling Laws (underpinning OpenAI o1 and DeepSeek-R1) formalizes the second paradigm of scaling: trading test-time compute FLOPs for sustained logarithmic/power-law accuracy gains on complex reasoning benchmarks; unlike standard single-pass greedy decoding, Inference-Time Scaling expands compute along 3 primary dimensions: 1) Best-of-

N

Sampling with Outcome/Process Reward Verifiers (sampling

N

parallel rollouts and selecting the highest-scoring trajectory); 2) Sequential Tree Search & MCTS (expanding reasoning search trees over thought tokens with dynamic value pruning); 3) Autoregressive Long CoT Self-Correction (allowing the policy to generate recursive backtracking tokens to self-correct reasoning flaws before committing to final answers).

💡Use Cases

International Mathematical Olympiad (IMO) theorem proving, competitive programming synthesis, and scientific hypothesis deduction.

⚡Key Problems Solved

Complex multi-step reasoning collapses under System-1 instantaneous next-token prediction; Inference-Time compute unlocks deliberative System-2 planning, reflection, and algorithmic search.
