Not to get hyperbolic, but the Edge could be the MacBook Air of smartphones (or, perhaps, the Samsung Galaxy Book Edge is a more fitting comparison).
The two rear cameras (versus three and four on the S25 and S25 Ultra, respectively) might have helped Samsung to reduce its weight.
As its name implies, the Edge is part of the Galaxy S25 range of flagship phones.
If the Edge has the same Snapdragon 8 Elite chip as the S25 Ultra, it should easily handle a top-notch display, buttery smooth resolution, and effortless multitasking.
The S25 Edge reportedly measures a mere 5.844mm in thickness, making it one of the slimmest flat phones on the market.
