Running Local AI Models in .NET with Ollama (Step-by-Step Guide)

Short summary

Ollama enables .NET developers to run large language models locally via a simple HTTP API, eliminating cloud dependencies and per-request pricing entirely. The tutorial demonstrates installing Ollama, downloading models (Llama3, Mistral, CodeLlama, Gemma), integrating them into ASP.NET Core with dependency injection and HTTP clients, and exposing a generated endpoint. Local AI suits privacy-critical work and cost-conscious teams; hybrid approaches work best in practice.

• •Ollama simplifies local AI deployment in .NET applications via HTTP APIs
• •Eliminates cloud dependency, API costs, and rate limits for cost-critical applications
• •Trade-offs: local models vs cloud providers; hybrid approaches often optimal
