Ollama is an open-source platform that enables developers to run AI models securely on their own machine without sharing data with external providers, providing a more secure and cheaper alternative to public model providers. It allows users to download and install the necessary software, navigate to the models section, select tools that support tool calling, and use visual IDEs like Langflow to build generative and agentic AI flows in a low-code or no-code environment. With Ollama, developers can confidently run models on their hardware, knowing that their data is safe and secure, without exposing it to public model providers. The platform supports local tool calling and agent interactions, making it suitable for running smaller machines. Users can experiment with their inputs, adjust the model's temperature settings, and integrate their Ollama agents into applications via API to enable full agentic capability.
