Try use this

var provider = new OllamaProvider(
            "http://localhost:11434",
            options: new RequestOptions
            {
                Temperature = 0,
                Stop = new[] { "Observation", "[END]" }, // add injection word `Observation` and `[END]` to stop the model(just as additional safety feature)
            });
        var model = new OllamaChatModel(provider, id: "llama3").UseConsoleForDebug();

look like the wiki page is outdate and need to be update

Yes, it's best to use these tests as an example, we are in the process of migrating documentation from wiki to mkdocs
