Tool calling に対応した AI モデル
ツール呼び出し / 関数呼び出しに対応する AI モデルの比較 —— エージェントと自動化に最適。
これは何か
- Tool calling（function calling）により、LLM が構造化 JSON で外部関数（検索・コード実行・DB クエリなど）の呼び出しを生成できます。
- モデルは関数名と引数を JSON で返し、ランタイムが実行して結果をツールメッセージとして戻します。
なぜ重要か
- ツール呼び出しがないと、エージェントは自由文を正規表現で解析する必要があり壊れやすいです。
- RAG、ReAct ループ、多段アシスタントを本番で安定させるのは Tool calling です。

Frequently asked questions
How many AI models support ツール呼び出し?
660 canonical models in our database currently support ツール呼び出し. 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 ツール呼び出し?
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 ツール呼び出し 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 ツール呼び出し.
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 ツール呼び出し 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.
