E-Bench-Code - Pass^3: leaderboard
E-Bench (Tencent Hunyuan, 2026) builds synthetic product environments modelled on Honor of Kings, QQ Music and Tencent Meeting with 323 state-changing tasks that require discovering hidden data and composing several tool calls, graded by exact database-state diff over three trials per task. In E-Bench-Code the agent also has an exec_code tool; this board is Pass^3, the share of tasks solved in all three trials, in percent, higher is better.
Metric: Pass^3 (%; tasks solved in all three trials; domain MCP tools plus an exec_code tool) on 323 synthetic state-changing tasks in three product environments (Honor of Kings, QQ Music, Tencent Meeting), graded by exact database-state diff; three trials per task, each model at its highest available thinking effort in a shared MCP harness. Source: arxiv.org. Saturation forecast: Around February 2027. 11 models tracked.
