# How can I log a metric that doesn't change over time such as a final evaluation accuracy?

To record a single, unchanging value such as a final evaluation accuracy, log it once with `run.log`. For example, `run.log({'final_accuracy': 0.9})` records the final accuracy. By default, `run.log({'final_accuracy': <value>})` updates `run.settings['final_accuracy']`, which reflects the value in the runs table.
