The original iPad Pro was introduced in September 2015, and ran iOS 9. It had an A9X chip, and came in two sizes: 9.7-inch and 12.9 inch; the 9.7 inch coming out in March 2016. The second-generation iPad Pro, unveiled in June 2017 at WWDC, had an upgraded A10X Fusion chip and swapped the 9.7-inch screen for a larger 10.5-inch display. The third-generation iPad Pro, announced in October 2018, was introduced with a new all screen design, eliminating the home button, and featured Face ID; it came in 11-inch and 12.9-inch models, the same screen sizes used by every subsequent model to date. The fourth-generation iPad Pro, introduced in March 2020, included the A12Z chip, and was introduced alongside a model of the Magic Keyboard for iPad. The fifth-generation iPad Pro, announced in April 2021, incorporated a desktop-class M1 chip, making it the first iPad model to not use an A-series processor. The sixth-, introduced in October 2022 alongside the 10th-generation iPad, includes the M2 chip, Apple Pencil Hover, and ProRes video. The seventh- and current-generation iPad Pro, introduced in May 2024 alongside the 6th-generation iPad Air, launched the M4 chip, Apple Pencil Pro, a new Magic Keyboard with function keys and is the first iPad with an OLED display.
