How to Implement Tool Calling with Gemma 4 and Python

# Plain-English Summary Google released a new free AI model called Gemma 4 that can now follow instructions to use tools and software—meaning it can do things like look up information or complete tasks without needing constant human guidance. This matters because it makes open-source AI more practical for real-world business problems, giving companies more options beyond expensive proprietary models. If you're considering AI tools for your organization, this update means there's a more capable free alternative worth evaluating.
