Covers installation, pulling models, calling Ollama from Python via its native SDK, the OpenAI-compatible SDK, and LangChain integration. Demonstrates a provider-agnostic factory pattern for switching between cloud and local models, and shows how to build a LangGraph ReAct agent backed by a local model. Uses FinanceGPT (a personal finance app processing bank statements and tax forms) as a real-world example. Also discusses tradeoffs including response quality, inference speed, hardware requirements, and function calling reliability. ## Full article daily.dev links to this article rather than hosting it.
