FAQ
Frequently asked questions
What is the best AI model for tool calling and function calling?
Rank 1 on this board is the conservative TrueSkill lead from LLM Stats with MCP Atlas as the named agent and tool-use eval. Use it when you care about calling tools and MCP-style agents, not when you only need LiveCodeBench code generation.
What is MCP Atlas on an LLM agent ranking?
MCP Atlas is the tool-calling and Model Context Protocol eval LLM Stats attaches to this board. It is closer to function calling and agent tool use than to GPQA or AIME. zerouter republishes the scores and does not run MCP Atlas.
How is a tool-calling leaderboard different from a coding leaderboard?
Coding here is LiveCodeBench program synthesis. Tool calling is whether the model selects and uses tools correctly. A coding lead can still miss tool schemas, so agent builders should read this board instead of copying the coding rank.
Why do agent rankings change faster than chat popularity lists?
Tool-calling evals move when labs ship new function-calling stacks. This table follows LLM Stats, which typically refreshes about hourly. Chat arena votes are a different signal and are not what this tool-calling board reports.
Where does the tool-calling LLM leaderboard data come from?
The tool calling ranking is republished from the public LLM Stats MCP Atlas board at llm-stats.com, including conservative TrueSkill where LLM Stats publishes it. zerouter does not run MCP Atlas or the other evals behind the board. Scores typically refresh about hourly.
