"1. **System Messages**: Use `SystemMessage` to set the model's behavior. This is similar to providing top-level instructions for tone, format, or specific behavior.\n",

"\u001b[36m> Response: A llama is a domesticated mammal native to South America, specifically the Andean region. It belongs to the camelid family, which also includes camels, alpacas, guanacos, and vicuñas.\n",
"\n",
"Here are some interesting facts about llamas:\n",
"\n",
"1. **Physical Characteristics**: Llamas are large, even-toed ungulates with a distinctive appearance. They have a long neck, a small head, and a soft, woolly coat that can be various colors, including white, brown, gray, and black.\n",
"2. **Size**: Llamas typically grow to be between 5 and 6 feet (1.5 to 1.8 meters) tall at the shoulder and weigh between 280 and 450 pounds (127 to 204 kilograms).\n",
"3. **Habitat**: Llamas are native to the Andean highlands, where they live in herds and roam freely. They are well adapted to the harsh, high-altitude climate of the Andes.\n",
"4. **Diet**: Llamas are herbivores and feed on a variety of plants, including grasses, leaves, and shrubs. They are known for their ability to digest plant material that other animals cannot.\n",
"5. **Behavior**: Llamas are social animals and live in herds. They are known for their intelligence, curiosity, and strong sense of self-preservation.\n",
"6. **Purpose**: Llamas have been domesticated for thousands of years and have been used for a variety of purposes, including:\n",
"\t* **Pack animals**: Llamas are often used as pack animals, carrying goods and supplies over long distances.\n",
"\t* **Fiber production**: Llama wool is highly valued for its softness, warmth, and durability.\n",
"\t* **Meat**: Llama meat is consumed in some parts of the world, particularly in South America.\n",
"\t* **Companionship**: Llamas are often kept as pets or companions, due to their gentle nature and intelligence.\n",
"\n",
"Overall, llamas are fascinating animals that have been an integral part of Andean culture for thousands of years.\u001b[0m\n"
