Google Chrome’s desktop version now features a Memory Saver mode which aims to reduce memory usage. The feature is becoming even more advanced in determining which tabs can be utilized to minimize memory usage.

A report from Windows Report revealed that the Probabilistic Memory Saver Mode is currently being tested in Google Chrome Canary version 121. Although it’s not enabled by default, users can locate it by typing “about://flags” into the address bar.

Memory Saver mode essentially puts inactive tabs to sleep to free up RAM for active tabs. However, this may result in a delay when reopening these inactive tabs. The new Probabilistic Memory Saver Mode leverages probability distributions to estimate the likelihood of tab revisit, which is expected to strike a better balance between memory saving and tab snoozing.

While Google has not officially announced the new feature, it appears that all open tabs will receive a probability score indicating the likelihood of them being reopened. This score may be based on the tab’s content, frequency of revisiting the tab, and its period of inactivity.

It remains uncertain whether this feature will be rolled out to the stable version of Chrome for all users. Nevertheless, any improvement to the Memory Saver feature is anticipated to be beneficial, with the potential for further tweaking and optimization based on testing.

This upgrade follows the addition made by Google in June, allowing users to view the RAM usage of each tab, making it easier to identify and close down high-consuming tabs if necessary.
