The Neural Network as Agent: How to Add Tools to Gemma 4
Gemma 4, Google's open model, can now work as an agent. A new tutorial shows how to teach the model to call tools on its own, such as searching the internet and performing calculations. The model decides for itself which tool to use. The tutorial is useful for ML engineers and data scientists who want to build smart agents without closed APIs.

Gemma 4, Google's open neural network, can now work as an autonomous agent, deciding on its own when a task calls for an information search and when it calls for calculations.
What is tool calling in neural networks?
Tool calling is a mechanism that lets neural networks go beyond text generation. Instead of simply writing an answer, the model can call a function, get the result and use it in its further reasoning.
How does Gemma 4 use tools as an agent?
For Gemma 4, this means it can choose on its own which tool to use, information search or calculations, depending on what the task requires.
