In this article, you will learn how Gemma 4, Llama 3, and Mistral implement tool calling locally, and what trade-offs each model family presents for real-world deployment.

Topics we will cover include:

What tool calling is and why it matters for locally deployed language models.

How each of the three model families — Gemma 4, Llama 3, and Mistral — implements tool calling, including architectural and versioning differences.

The practical strengths and trade-offs of each family for different hardware constraints and deployment contexts.
