On Turn-Level Best-of-N Sampling for Scaling LLM Agents

- What happened
- Researchers tested turn-level best-of-N sampling for LLM agents, where one model generates candidate actions and another selects the best one at each step.
- Why it matters
- Matters for engineers building long-horizon autonomous agents who want inference-time improvements without retraining models.
- Watch out
- Results show 5-10% accuracy gains on tested tasks, but generalization to other domains and the computational cost of running multiple models remains unclear.
