Data / the numbers behind AI

We watch the numbers behind AI every day and show you the pictures.

Four charts today. More land every week — each one says when. Once a month we put the pictures in one book; when we work something out, we give you the sheet.

How we gather it / and what it costs

Why so few today

We only show a number once our own job has fetched it and written it down with the date. We do not copy anyone's table to fill the page. Every week this page fills up a little more, and it never goes back.

we measured it
We ran it ourselves and wrote down what happened.
we gathered it
Someone else published it and our job fetched it, with the date.
we worked it out
We did the arithmetic on numbers we already had, and show the working.
