The Download: OpenAI’s caste bias problem, and how AI videos are made

Caste bias is rampant in OpenAI’s products, including ChatGPT, according to an MIT Technology Review investigation.

But AI models continue to reproduce socioeconomic and occupational stereotypes that render Dalits as dirty, poor, and performing only menial jobs. Read the full story.

MIT Technology Review Narrated: how do AI models generate videos?

It’s been a big year for video generation. The downside is that creators are competing with AI slop, and social media feeds are filling up with faked news footage. Video generation also uses up a huge amount of energy, many times more than text or image generation.

With AI-generated videos everywhere, let's take a moment to talk about the tech that makes them work.
