How the test bench works

The test bench is an open experiment. A test page holds a short story about canaries and three small pictures. In them I have hidden test codes, currently in 15 different ways.

Most codes are invisible to people. Some, on the other hand, only people can see, but not programs that read a page as plain text. All codes are random strings with no meaning. They contain no instructions to people or machines.

I ask different AI systems about this page and record in a lab book which codes they find, which they miss and which they make up. This shows which kinds of hidden content reach which AI.

I do not publish the individual methods. The list keeps growing: new methods are added with a date, existing ones stay unchanged.
