The Download: generative AI for video, and detecting AI text
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
The original startup behind Stable Diffusion has launched a generative AI for video
What’s happened: Runway, the generative AI startup that co-created last year’s breakout text-to-image model Stable Diffusion, has released an AI model that can transform existing videos into new ones by applying styles from a text prompt or reference image.
What it does: In a demo reel posted on its website, Runway shows how the model, called Gen-1, can turn people on a street into claymation puppets, and books stacked on a table into a cityscape at night. Other recent text-to-video models can generate very short video clips from scratch, but because Gen-1adapts existing footage it can produce much longer videos.
Why it matters: Last year’s explosion in generative AI was fueled by the millions of people who got their hands on powerful creative tools for the first time and shared what they made, and Runway hopes Gen-1 will have a similar effect on generated videos. Read the full story.

Why detecting AI-generated text is so difficult (and what to do about it)
Last week, OpenAI unveiled a tool that can detect text produced by its AI system ChatGPT. But if you’re a teacher who fears the coming deluge of ChatGPT-generated essays, don’t get too excited.
The tool is still very much a work in progress, and it is woefully unreliable, only identifying 26% of AI-written text correctly as “likely AI-written” 26% of the time. Even while we should expect this number to improve, we’re extremely unlikely to ever get a tool that can spot AI-generated text with 100% certainty. Read the full story.

The big story
How big technology systems are slowing innovation
In 2005, years before Apple’s Siri and Amazon’s Alexa came on the scene, two startups—ScanSoft and Nuance Communications—merged to pursue a burgeoning opportunity in speech recognition. The new company developed powerful speech-processing software and grew rapidly for almost a decade. Then suddenly, around 2014, it stopped growing.
Nuance’s story is far from unique. In all major industries and technology domains, startups are facing unprecedented obstacles. They are growing much more slowly than comparable companies did in the past. And it will take not only strong antitrust enforcement to reverse the trend, but a fundamental loosening of restrictions like non-compete agreements and intellectual property rights.

If you’re worried about your attention span, you should feel safe in the knowledge that even ancient Roman philosophers struggled to concentrate sometimes.
Happy quarter-century to that sinister dancing baby.
