'Think Again or Think Longer?' Frames Test-Time Compute as an Explicit Budget Decision

arXiv·low signal

'Think Again or Think Longer?' (arXiv 2606.19808, June 18) studies budget-aware reasoning — when an agent should retry/rethink versus extend a single chain of thought — under cost constraints. It reframes test-time compute allocation as an explicit budget decision rather than a fixed setting. Practical for anyone optimizing inference spend across a multi-step pipeline where reasoning cost compounds per stage.
