Três. Ou quatro incluindo o beta pré-Matrix

After the Machine war ended, the remaining surviving humans were taken to be studied and plugged into an initial first power plant matrix without their awareness of being plugged into that matrix.
O que foi seguido pela Paradise Matrix :
The Paradise Matrix was the first prototype Matrix, which was designed by The Architect to control humanity by putting their minds into a constructed virtual reality. Unlike later versions, it simulated a perfect world with no suffering to try to pacify their minds, but the human minds did not accept this version. Many of those connected died, and a Nightmare Matrix was designed in its place that tried to correct its flaws.
O que foi seguido pela Matriz do pesadelo :
The Nightmare Matrix was the second prototype Matrix, designed by The Architect after the massive failure of the Paradise Matrix in the hope that human minds would more readily accept an imperfect world with suffering. Unlike the first version, this Matrix instituted a basic cause-and-effect programming and forcibly made those connected to it accept the program.
E finalmente a Modern Matrix , que é a que vemos nos filmes:
The solution was ultimately stumbled upon by an intuitive program, originally intended to study aspects of the human psyche: The Oracle. She discovered that if humans were given a choice, even at a subconscious level, to accept the reality of the world around them, ninety-nine percent of humans would accept the virtual world.
