OpenAI has finally released open-weight language models
The news: OpenAI has finally released its first open-weight large language models since 2019’s GPT-2. Unlike the models available through OpenAI’s web interface, these new open models can be freely downloaded, run, and even modified on laptops and other local devices.
Why it matters: These releases re-establish OpenAI as a presence for users of open models. That’s particularly notable at a time when Meta, which had previously dominated the American open-model landscape with its Llama models, may be reorienting toward closed releases—and when Chinese open models are becoming more popular than their American competitors.

MIT Technology Review Narrated: AI means the end of internet search as we’ve known it
The biggest change to the way search engines deliver information to us since the 1990s is happening right now. No more keyword searching. Instead, you can ask questions in natural language. And instead of links, you’ll increasingly be met with answers written by generative AI and based on live information from across the internet, delivered the same way.
Not everyone is excited for the change. Publishers are completely freaked out. And people are also worried about what these new LLM-powered results will mean for our fundamental shared reality.
This is our latest story to be turned into a MIT Technology Review Narrated podcast, which we publish each week on Spotify and Apple Podcasts. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released.

One more thing

Future space food could be made from astronaut breath
The future of space food could be as simple—and weird—as a protein shake made with astronaut breath or a burger made from fungus.
For decades, astronauts have relied mostly on pre-packaged food during their forays off our planet. With missions beyond Earth orbit in sight, a NASA-led competition is hoping to change all that and usher in a new era of sustainable space food.
To solve the problem of feeding astronauts on long-duration missions, NASA asked companies to propose novel ways to develop sustainable foods for future missions. Around 200 rose to the challenge—creating nutritious (and outlandish) culinary creations in the process. Read the full story.
