The Overture Maps Foundation (OMF) is a collaborative effort by Amazon Web Services (AWS), Meta, Microsoft, and TomTom "to enable current and next-generation interoperable open map products". This is their first open map dataset.
I add it through their web interface. I signed up several years ago, but I spent 2020 and 2021 updating OSM for my city to be as good as Google Maps for major places, posting their open and close times, better pin placement and such.
OSM is very strict about verifiability of data. It is speculated that Overture is (because it also uses OSM data) meant to contain a lot more data that isn't as strictly verifiable. Think AI generated building footprints.
Ah, that's actually pretty cool if it's sufficiently open. OSM is pretty lacking where I am, and I know, I can contribute to it, but I really don't have the capacity to figure that all out right now.
