ChatClovaX

This notebook provides a quick overview for getting started with Naver’s HyperCLOVA X chat models via CLOVA Studio. For detailed documentation of all ChatClovaX features and configurations head to the API reference.

CLOVA Studio has several chat models. You can find information about latest models and their costs, context windows, and supported input types in the CLOVA Studio Guide documentation.

Setup​

Before using the chat model, you must go through the four steps below.

  1. Creating NAVER Cloud Platform account
  2. Apply to use CLOVA Studio
  3. Create a CLOVA Studio Test App or Service App of a model to use (See here.)
  4. Issue a Test or Service API key (See here.)

Credentials​

Set the CLOVASTUDIO_API_KEY environment variable with your API key.

You can add them to your environment variables as below:

export CLOVASTUDIO_API_KEY="your-api-key-here"
import getpass
import os

if not os.getenv("CLOVASTUDIO_API_KEY"):
    os.environ["CLOVASTUDIO_API_KEY"] = getpass.getpass(
        "Enter your CLOVA Studio API Key: "
    )

To enable automated tracing of your model calls, set your LangSmith API key:

# os.environ["LANGSMITH_TRACING"] = "true"
# os.environ["LANGSMITH_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")

Installation​

The LangChain Naver integration lives in the langchain-naver package:

# install package
%pip install -qU langchain-naver

Instantiation​

Now we can instantiate our model object and generate chat completions:

from langchain_naver import ChatClovaX

chat = ChatClovaX(
    model="HCX-005",
    temperature=0.5,
    max_tokens=None,
    timeout=None,
    max_retries=2,
    # other params...
)

Invocation​

In addition to invoke, ChatClovaX also support batch and stream functionalities.

messages = [
    (
        "system",
        "You are a helpful assistant that translates English to Korean. Translate the user sentence.",
    ),
    ("human", "I love using NAVER AI."),
]

ai_msg = chat.invoke(messages)
ai_msg
AIMessage(content='네이버 인공지능을 사용하는 것을 정말 좋아합니다.', additional_kwargs={'refusal': None}, response_metadata={'token_usage': {'completion_tokens': 11, 'prompt_tokens': 28, 'total_tokens': 39, 'completion_tokens_details': None, 'prompt_tokens_details': None}, 'model_name': 'HCX-005', 'system_fingerprint': None, 'id': 'b70c26671cd247a0864115bacfb5fc12', 'finish_reason': 'stop', 'logprobs': None}, id='run-3faf6a8d-d5da-49ad-9fbb-7b56ed23b484-0', usage_metadata={'input_tokens': 28, 'output_tokens': 11, 'total_tokens': 39, 'input_token_details': {}, 'output_token_details': {}})
print(ai_msg.content)
네이버 인공지능을 사용하는 것을 정말 좋아합니다.

Chaining​

We can chain our model with a prompt template like so:

from langchain_core.prompts import ChatPromptTemplate

prompt = ChatPromptTemplate.from_messages(
    [
        (
            "system",
            "You are a helpful assistant that translates {input_language} to {output_language}. Translate the user sentence.",
        ),
        ("human", "{input}"),
    ]
)

chain = prompt | chat
chain.invoke(
    {
        "input_language": "English",
        "output_language": "Korean",
        "input": "I love using NAVER AI.",
    }
)
API Reference:ChatPromptTemplate
AIMessage(content='저는 네이버 인공지능을 사용하는 것을 좋아합니다.', additional_kwargs={'refusal': None}, response_metadata={'token_usage': {'completion_tokens': 10, 'prompt_tokens': 28, 'total_tokens': 38, 'completion_tokens_details': None, 'prompt_tokens_details': None}, 'model_name': 'HCX-005', 'system_fingerprint': None, 'id': 'b7a826d17fcf4fee8386fca2ebc63284', 'finish_reason': 'stop', 'logprobs': None}, id='run-35957816-3325-4d9c-9441-e40704912be6-0', usage_metadata={'input_tokens': 28, 'output_tokens': 10, 'total_tokens': 38, 'input_token_details': {}, 'output_token_details': {}})

Streaming​

system = "You are a helpful assistant that can teach Korean pronunciation."
human = "Could you let me know how to say '{phrase}' in Korean?"
prompt = ChatPromptTemplate.from_messages([("system", system), ("human", human)])

chain = prompt | chat

for chunk in chain.stream({"phrase": "Hi"}):
    print(chunk.content, end="", flush=True)
In Korean, the informal way of saying 'hi' is "안녕" (annyeong). If you're addressing someone older or showing more respect, you would use "안녕하세요" (annjeonghaseyo). Both phrases are used as greetings similar to 'hello'. Remember, pronunciation is key so make sure to pronounce each syllable clearly: 안-녀-엉 (an-nyeo-eong) and 안-녕-하-세-요 (an-nyeong-ha-se-yo).

Additional functionalities​

Using fine-tuned models​

You can call fine-tuned models by passing the task_id to the model parameter as: ft:{task_id}.

You can check task_id from corresponding Test App or Service App details.

fine_tuned_model = ChatClovaX(
    model="ft:a1b2c3d4",  # set as `ft:{task_id}` with your fine-tuned model's task id
    # other params...
)

fine_tuned_model.invoke(messages)
AIMessage(content='네이버 인공지능을 사용하는 것을 정말 좋아합니다.', additional_kwargs={'refusal': None}, response_metadata={'token_usage': {'completion_tokens': 11, 'prompt_tokens': 28, 'total_tokens': 39, 'completion_tokens_details': None, 'prompt_tokens_details': None}, 'model_name': 'HCX-005', 'system_fingerprint': None, 'id': '2222d6d411a948c883aac1e03ca6cebe', 'finish_reason': 'stop', 'logprobs': None}, id='run-9696d7e2-7afa-4bb4-9c03-b95fcf678ab8-0', usage_metadata={'input_tokens': 28, 'output_tokens': 11, 'total_tokens': 39, 'input_token_details': {}, 'output_token_details': {}})
