ToolMaze - Perturbed Task Success: leaderboard

ToolMaze (2026) tests tool-using LLM agents on 400 DAG-structured tasks over 270 tools, each also run with injected tool failures that are explicit or implicit and transient or permanent. This board is the task success rate in percent averaged over the four failure modes, under the standard tool-use prompt; higher is better.

Metric: Task success rate (%) averaged over the four tool-failure modes, macro-averaged over the four topology levels; 400 DAG-structured tool-use tasks (four topology levels) over 270 tools, each also run under four injected tool-failure modes (explicit or implicit, transient or permanent); sandboxed, 25 agent steps, temperature 1, the standard tool-use prompt; higher is better.
