    Class Ollama

    Class that represents the Ollama language model. It extends the base LLM class and implements the OllamaInput interface.

    const ollama = new Ollama({
      baseUrl: "http://api.example.com",
      model: "llama3",
    });

    // Streaming translation from English to German
    const stream = await ollama.stream(
      `Translate "I love programming" into German.`
    );

    const chunks = [];
    for await (const chunk of stream) {
      chunks.push(chunk);
    }

    console.log(chunks.join(""));
