Evaluate your LLM App

This is 5 main lines:

from ragas.metrics import AspectCritic

test_data = {
    "user_input": "summarise given text\nThe company reported an 8% rise in Q3 2024, driven by strong performance in the Asian market. Sales in this region have significantly contributed to the overall growth. Analysts attribute this success to strategic marketing and product localization.

    "response": "The company experienced an 8% increase in Q3 2024, largely due to effective marketing strategies and product adaptation, with expectations of continued growth in the coming quarter.",
}
evaluator_llm = LangchainLLMWrapper(ChatOpenAI(model="gpt-4o"))
metric = AspectCritic(name="summary_accuracy",llm=evaluator_llm, definition="Verify if the summary is accurate.")
await metric.single_turn_ascore(SingleTurnSample(**test_data))
