LAS VEGAS — Welcome to the age of supercomputing for everyone.

On Thursday IBM will announce that Watson, the computing system that beat all the humans on “Jeopardy!” two years ago, will be available in a form more than twice as powerful via the Internet.

Companies, academics and individual software developers will be able to use it at a small fraction of the previous cost, drawing on IBM’s specialists in fields like computational linguistics to build machines that can interpret complex data and better interact with humans.

IBM’s move to make its marquee technology more widely available is the latest effort among big technology companies to make the world’s most powerful computers as accessible as the Angry Birds video game.

It is also an indication of how quickly the technology industry is changing, from complex systems that cost millions to install to pay-as-you-go deals that provide small companies and even individuals access to technology that just a few years ago only the largest companies could afford.
