langchain

Opik integrates with Langchain to allow you to log your Langchain calls to the Opik platform, simply wrap the Langchain client with OpikTracer to start logging:

from langchain.chains import LLMChain
from langchain_openai import OpenAI
from langchain.prompts import PromptTemplate
from opik.integrations.langchain import OpikTracer

# Initialize the tracer
opik_tracer = OpikTracer()

# Create the LLM Chain using LangChain
llm = OpenAI(temperature=0)

prompt_template = PromptTemplate(
   input_variables=["input"],
   template="Translate the following text to French: {input}"
)

llm_chain = LLMChain(llm=llm, prompt=prompt_template)

# Generate the translations
translation = llm_chain.run("Hello, how are you?", callbacks=[opik_tracer])
print(translation)
