Voyage

Milvus поддерживает модель реранкера Voyage с помощью класса VoyageRerankFunction. Эта функциональность позволяет эффективно оценивать релевантность пар запрос-документ.

Чтобы воспользоваться этой функцией, установите необходимые зависимости:

pip install --upgrade pymilvus
pip install "pymilvus[model]"

Затем инстанцируйте класс VoyageRerankFunction:

from pymilvus.model.reranker import VoyageRerankFunction

# Define the rerank function
voyage_rf = VoyageRerankFunction(
    model_name="rerank-lite-1",  # Specify the model name. Defaults to `rerank-lite-1`.
    api_key=VOYAGE_API_KEY # Replace with your Voyage API key
)

Параметры:

• model_name (string)

  Имя модели Voyage, которую следует использовать для кодирования. Если оставить этот параметр неуказанным, будет использована модель rerank-lite-1. Список доступных моделей см. в разделе Реранкеры.

• api_key (строка)

  API-ключ для доступа к API Voyage. Информацию о том, как создать API-ключ, см. в разделе API-ключ и Python-клиент.

Затем используйте следующий код для ранжирования документов на основе запроса:

query = "What event in 1956 marked the official birth of artificial intelligence as a discipline?"

documents = [
    "In 1950, Alan Turing published his seminal paper, 'Computing Machinery and Intelligence,' proposing the Turing Test as a criterion of intelligence, a foundational concept in the philosophy and development of artificial intelligence.",
    "The Dartmouth Conference in 1956 is considered the birthplace of artificial intelligence as a field; here, John McCarthy and others coined the term 'artificial intelligence' and laid out its basic goals.",
    "In 1951, British mathematician and computer scientist Alan Turing also developed the first program designed to play chess, demonstrating an early example of AI in game strategy.",
    "The invention of the Logic Theorist by Allen Newell, Herbert A. Simon, and Cliff Shaw in 1955 marked the creation of the first true AI program, which was capable of solving logic problems, akin to proving mathematical theorems."
]

results = voyage_rf(
    query=query,
    documents=documents,
    top_k=3,
)

for result in results:
    print(f"Index: {result.index}")
    print(f"Score: {result.score:.6f}")
    print(f"Text: {result.text}\n")

Ожидаемый результат будет похож на следующий:
