Minimize accessToken calls to Okta from Salesforce

We use the accessToken for the logged-in user when making API calls for user session validation.

When we do an Auth.AuthToken.getAccessToken() call, does Salesforce save the token locally, or does it go to the Okta every time we call Auth.AuthToken.getAccessToken()?

I’m trying to minimize the number of accessToken calls to Okta as we are hitting the rate limit.

Thanks in advance for your comments/answers.
