Custom Roles

Allows to manage custom roles (apart from the base roles) for chat interactions with the models.

Particularly helpful when you would need to use different roles that the newer models support other than the base roles.

Base roles are SYSTEM, USER, ASSISTANT, TOOL.

Usage

Add new role

import io.github.ollama4j.Ollama;
import io.github.ollama4j.models.chat.OllamaChatMessageRole;

public class Main {

    public static void main(String[] args) {
        String host = "http://localhost:11434/";
        Ollama ollama = new Ollama(host);

        OllamaChatMessageRole customRole = ollama.addCustomRole("custom-role");
    }
}

List roles

import io.github.ollama4j.Ollama;
import io.github.ollama4j.models.chat.OllamaChatMessageRole;

public class Main {

    public static void main(String[] args) {
        String host = "http://localhost:11434/";
        Ollama ollama = new Ollama(host);

        List<OllamaChatMessageRole> roles = ollama.listRoles();
    }
}

Get role

import io.github.ollama4j.Ollama;
import io.github.ollama4j.models.chat.OllamaChatMessageRole;

public class Main {

    public static void main(String[] args) {
        String host = "http://localhost:11434/";
        Ollama ollama = new Ollama(host);

        List<OllamaChatMessageRole> roles = ollama.getRole("custom-role");
    }
}
