We introduce NATURAL PLAN, a realistic planning benchmark in natural language containing 3 key tasks: Trip Planning, Meeting Planning, and Calendar Scheduling. We focus our evaluation on the planning capabilities of LLMs with full information on the task, by providing outputs from tools such as Google Flights, Google Maps, and Google Calendar as contexts to the models. This eliminates the need for a tool-use environment for evaluating LLMs on Planning. We observe that NATURAL PLAN is a challenging benchmark for state of the art models. For example, in Trip Planning, GPT-4 and Gemini 1.5 Pro could only achieve 31.1% and 34.8% solve rate respectively. We find that model performance drops drastically as the complexity of the problem increases: all models perform below 5% when there are 10 cities, highlighting a significant gap in planning in natural language for SoTA LLMs. We also conduct extensive ablation studies on NATURAL PLAN to further shed light on the (in)effectiveness of approaches such as self-correction, few-shot generalization, and in-context planning with long-contexts on improving LLM planning.

    cs.AI 2026-01 conditional novelty 6.0 of 10

    SCOPE separates query-specific reasoning from reusable solver code and reports state-of-the-art success rates on TravelPlanner and Natural Plan at lower token cost.

  7. ISO-Bench: Benchmarking Multimodal Causal Reasoning in Visual-Language Models through Procedural Plans

    cs.CL 2025-07 reject novelty 6.0 of 10

    ISO-Bench is presented as a benchmark for cross-modal causal reasoning, but its positive and negative examples are constructed from temporal position, allowing a non-causal image-text matching shortcut.

    cs.AI 2025-06 conditional novelty 6.0 of 10

    LogiPlan introduces a three-task benchmark with controllable graph complexity, showing that although reasoning models excel at plan generation, all models degrade sharply on cycle detection and deep comparison questions.

  9. Flex-TravelPlanner: A Benchmark for Flexible Planning with Language Agents

    cs.CL 2025-06 conditional novelty 6.0 of 10

    A new multi-turn benchmark shows LLMs struggle to keep global constraints satisfied when local constraints are added later, and often sacrifice budget to satisfy soft preferences.
