1. PlayStation 4 (Fat): The original PS4, often referred to as the "Fat" model, was the first iteration of the console. It features a large, angular design with a black finish and a 500GB or 1TB hard drive. The PS4 supports 1080p gaming, streaming, and multimedia features. It is powered by a custom AMD processor and has a robust library of exclusive games like Uncharted and The Last of Us Remastered.
2. PlayStation 4 Slim: Released in 2016, the PS4 Slim is a more compact and lightweight version of the original PS4. It has the same performance as the original model but in a smaller and more energy-efficient design. The PS4 Slim features a 500GB or 1TB hard drive and maintains the same powerful gaming capabilities but is quieter and more affordable than the original.
3. PlayStation 4 Pro: The PS4 Pro, launched in 2016, is an upgraded version with enhanced hardware, including a more powerful GPU and CPU for 4K gaming support. This version is designed for gamers who want improved graphics, better frame rates, and an overall more immersive experience. It comes with a 1TB hard drive and is slightly larger than the Slim version.

All PS4 models come in a sleek black finish, with the console providing access to a vast library of games, entertainment apps, and online services through PlayStation Network (PSN). The DualShock 4 controller, with its touchpad and improved ergonomics, is also a key part of the PS4 experience.
