Cannot reach a local model server

Symptom

AIError.transport(...) mentioning a refused connection to localhost:11434.

Why it happens

OllamaModel defaults to http://localhost:11434/v1. The server is not running, is bound elsewhere, or the model was never pulled.

Fix

Start the server and pull a model:

ollama serve
ollama pull qwen3

For a non-default host, pass baseURL: explicitly. Note that a model Ollama has not pulled fails at request time, not at construction, so a typo in the model id looks like a server problem.
