PlanningBench: Generating Scalable and Verifiable Planning Data for Evaluating and Training Large Language Models
PlanningBench is a new framework designed to generate scalable and verifiable planning data for evaluating and training large language models. It addresses limitations in existing benchmarks by allowing for controllable generation of planning scenarios based on a structured taxonomy. The framework has shown to improve performance in planning tasks and instruction-following tasks through reinforcement learning on verified data.
- ▪PlanningBench abstracts practical workflows into a structured taxonomy of over 30 task types and difficulty factors.
- ▪The framework enables adaptive difficulty control and quality filtering for planning problems.
- ▪Current large language models struggle to produce complete solutions under coupled constraints, as revealed by evaluations using PlanningBench.
