The Google Prediction AI provides access to Google's AI tools that it uses internally for  a range of classification and prediction tasks.

It basically is a REST style API to a general purpose pattern recognition engine. You can upload some data, which can be unstructured text or numeric, to Google Storage for Developers. You then perform a supervised learning stage and finally you can use the trained model to classify new data.

Until recently it has been in a closed beta and essentially getting to use it was by invitation only. Now it looks as if a paid for service is the next step. It currently still isn't clear if Google are going to throw the service open to all - at the moment you still have to apply for access.

After the free period Google will charge:

• $10 monthly fee per project. A project is defined by a unique key on the Google APIs console.
• The monthly fee covers 10,000 additional predictions per month. Beyond that, predictions cost $0.50 per 1,000 predictions. If you intend to make more than 40,000 predictions per day, please contact us. Google Prediction has an absolute limit of 60,000 predictions per day.
• $0.002 per MB trained (maximum size of each dataset: 100MB)

You can monitor your use of the service and configure it via the Google API console.

The bottom line seems to be that there is a profit to be made from AI - well there is at least for Google.
