# Factual Accuracy

> Verifies if the provided output is factually correct based on the given information or the absence thereof. It ensures that the output maintains factual integrity and does not introduce inaccuracies.

<Warning>
  `factual_accuracy` is being deprecated. Avoid using it for new integrations.
  Use `groundedness` for new implementations.
</Warning>

### What to Do When Factual Accuracy Evaluation Gives a Low Score

When factual accuracy evaluation gives a low score, it is essential to reassess the evaluation criteria to ensure they are clearly defined and aligned with the evaluation's goals. If necessary, adjustments should be made to enhance the criteria's comprehensiveness and relevance. Additionally, the output should be thoroughly examined for factual inaccuracies, identifying any discrepancies and refining the content to improve factual correctness.

### Differentiating Factual Accuracy with [Groundedness](/future-agi/get-started/evaluation/builtin-evals/groundedness)

Factual accuracy focuses on verifying the correctness of the output based on the given input and context, ensuring that the information presented is factually sound. In contrast, groundedness ensures that the response strictly adheres to the provided context, preventing the inclusion of unsupported or external information.

While factual accuracy requires input, output, and context for evaluation, groundedness only requires a response and its context.
