AI Models with Tool Calling Support
Compare AI models that support tool calling / function calling for agents and automation.
這是什麼？
- Tool calling (also called function calling) lets an LLM emit a structured JSON request to invoke an external function — search, code execution, database queries, anything you expose.
- The model returns the function name and arguments as JSON; your runtime executes it and feeds the result back as a tool message.
為什麼重要
- Without tool calling, building agents requires brittle regex parsing of free-form text.
- Tool calling is what makes RAG, ReAct loops and multi-step assistants reliable in production.

Frequently asked questions
How many AI models support 工具呼叫?
660 canonical models in our database currently support 工具呼叫. The list is regenerated on every data refresh, so it always reflects the latest model releases from models.dev.
What is the cheapest model with 工具呼叫?
Voxtral Small 24B 2507 from Mistral is currently the lowest-priced option, at $0.002 per 1M input tokens and $0.002 per 1M output tokens. The full table above is sorted price-ascending.
Which model with 工具呼叫 has the largest context window?
Qwen Long (Alibaba (Qwen)) leads on context at 10M tokens. This may matter if you also need long-document understanding alongside 工具呼叫.
Which models are available on the most providers?
Production-readiness usually correlates with how many independent providers host the same weights. The top three by provider count are: Kimi K2.5 (45), MiniMax-M2.5 (40), GLM-5 (38).
How is 工具呼叫 different from a regular LLM?
Tool calling lets the model emit a structured JSON request to invoke an external function (search, code execution, DB query) instead of replying with prose. Without it, agents must parse freeform text — fragile and slow.
How often is this list updated?
Daily. Our data pipeline pulls models.dev once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
