We use this at scite [1] to power some of our features, kudos to Jason, Heather and the rest of the team for their awesome work on maintaining this infrastructure (and the rest of their work on Unpaywall, etc.)
For context, many companies, including us, used Microsoft Academic Graph but it was shuttered last year [2]. So OpenAlex came in to replace, but they also made it backwards compatible with the MAG data, making it super easy for us to migrate.
Overall there are some problems with the data that we've found and reported / fixed (and continue to do so), but it feels well supported to use moving forward.
I believe the OpenAlex team put out a preprint about this recently [3].
