01IntelligenceLab /Long-Horizon-Terminal-Bench Long-Horizon Terminal-Bench (LHTB) LHTB is a 46-task benchmark for measuring how well LLM agents sustain useful work in a containerized terminal over hundreds of steps. Unlike short-horizon coding benchmarks where an agent writes one artifact and stops, LHTB drops the agent into a stateful environment and grades it with hidden, rebuild-from-artifact verifiers — self-reported progress does not count. 📝 Blog: https://zli12321.github.io/LHTB/ 🏆 Leaderboard:… See the full description on the dataset page: https://huggingface.co/datasets/IntelligenceLab/Long-Horizon-Terminal-Bench.documenttext-generationn<1K136 likes13k downloads9d agoHugging Face02arvindh75 /Long-Horizon-Execution Long Horizon Execution This project contains the dataset accompanying the paper "The Illusion of Diminishing Returns: Measuring Long Horizon Execution in LLMs" Abstract Does continued scaling of large language models (LLMs) yield diminishing returns? Real-world value often stems from the length of task an agent can complete. We start this work by observing the simple but counterintuitive fact that marginal gains in single-step accuracy can compound into exponential… See the full description on the dataset page: https://huggingface.co/datasets/arvindh75/Long-Horizon-Execution.texttext-generationn<1K16 likes293 downloads1y agoHugging Face03ToolGym /long-horizon-traj long-horizon-traj Long-horizon agent trajectories with multi-step planning and constraints Dataset Description This dataset contains agent trajectories for multi-turn tool use tasks, including reasoning traces, tool calls, and responses.
