Introduction: The Shift Toward Private, On-Premise AI For the past two years, the software engineering world has been obsessed with cloud-based large language models (LLMs) like GPT-4, Claude, and Gemini. However, a quiet revolution is taking place in enterprise Java departments. Concerns over data privacy, latency, and API costs are driving developers to run LLMs locally. Enter Ollama – the tool that makes running models like Llama 3, Mistral, and Phi-3 as easy as ollama run llama3 . But Java developers face a critical question: How do we bridge the gap between Ollama’s Go/Echo HTTP server and a production-grade JVM application?
