I wouldn't exactly call it a teaser. The formulas they published stand on their own, and putting them out there in the wake of all the press of the AlphaTensor paper, is just a good idea.
Of course, these formulas are not super interesting on their own, and so the forthcoming paper on HOW they developed these formulas is in some sense the "real" paper.
