## About DeepPlanning

- Year: 2026
- Tasks: Travel planning and constrained shopping
- Format: Long-horizon planning benchmark
- Difficulty: Constrained agent planning
- Paper: [DeepPlanning: Benchmarking Long-Horizon Agentic Planning with Verifiable Constraints](https://arxiv.org/abs/2601.18137)

DeepPlanning focuses on global constrained optimization rather than local next-step reasoning. It is useful because many agents can execute short actions but still fail when they must gather information and plan coherently over a long horizon under hard constraints.

DeepPlanning is currently displayed on BenchLM for reference, but it is excluded from the weighted scoring formula.
