Why local is different
Ollama removes the Groq cloud key from the inference path, but it still needs local storage, memory, a running service, and a downloaded model. 'Local' does not mean zero setup or guaranteed performance.
Connection checks
Start Ollama before Minecraft. If a log says localhost:11434 refused the connection, verify the process and local firewall. Do not expose the Ollama port to the internet to make a local mod work.
Model and performance
Use the exact model or compatibility advice from the maintainer tutorial. A larger model can increase latency or exhaust RAM; test a small disposable world before moving an existing save.
