An AI algorithm is capable of automatically generating realistic-looking images from bits of pixels.

Why it matters: The achievement is the latest evidence that AI is increasingly able to learn from and copy the real world in ways that may eventually allow algorithms to create fictional images that are indistinguishable from reality.

What's new: In a paper presented at this week's International Conference on Machine Learning, researchers from OpenAI showed they could train the organization's GPT-2 algorithm on images.

  • GPT-2 is best known as a text-generating algorithm, capable of absorbing the structure of language by training on billions of words off the internet and then "writing" passable text from a simple prompt.
  • After training on images, the OpenAI algorithm — now called iGPT — could be fed a visual prompt in the form of half an image and then fill in the rest of it.

How it works: Unlike algorithms that use supervised learning, which requires laborious amounts of labeled data, iGPT and GPT-2 use unsupervised learning on unlabeled data. That means much less human effort.

  • As Karen Hao points out in MIT Tech Review, the fact that both iGPT and GPT-2 use the same algorithm for different purposes is early evidence of more generalizable machine intelligence — which is, after all, OpenAI's aim.

What to watch: A few weeks ago OpenAI released GPT-3, as well as a new API for the tool, which is essentially "a robot that can write anything," as the journalist Alex Hern puts it.

The bottom line: A world where you can ask a robot to write, or create an image of, anything may be just around the corner, which is both exciting and terrifying.

President Trump told the New York Post on Thursday that he plans to deliver his Republican National Convention speech from the White House lawn, despite bipartisan criticism of the optics and legality of the location.

Why it matters: Previous presidents avoided blurring staged campaign-style events — like party conventions — with official business of governing on the White House premises, per Politico.

Fauci's guidance on pre-vaccine coronavirus treatments

Antibody drugs and various medicine cocktails against the coronavirus are progressing and may provide some relief before vaccines.

The big picture: Everyone wants to know how and when they can return to "normal" life, as vaccines are not expected to be ready for most Americans for at least a year. Two therapies are known to be helpful, and more could be announced by late September, NIAID Director Anthony Fauci tells Axios.
