PluginEval: leaderboard

PluginEval (2026) is a Chinese function-calling benchmark of 3,000 human-verified queries over 54 plugins, with gold calls validated by real API execution and 500 adversarial negatives on which no tool should be called. Query-level accuracy counts a positive query as correct only when every required tool is called with grounded arguments, and a negative query when the model abstains; percent, higher is better.

Metric: Query-level accuracy (%; correct tool calls with correct arguments on positive queries and abstention on negative queries; original difficulty distribution; 3,000 human-verified Chinese function-calling queries over 54 plugins and 63 tools with real API execution (2,500 positive queries requiring grounded calls, 500 adversarial negatives requiring abstention; easy/medium/hard 0.4/0.4/0.2); GPT-5.2 judge anchored to gold annotations). Source: arxiv.org. Saturation forecast: Around February 2027. 5 models tracked.
