It’s high time for more AI transparency

In less than a week since Meta launched its open source AI model, LLaMA 2, startups and researchers have already used it to develop a chatbot and an AI assistant. It will be only a matter of time until companies start launching products built with it.

LLaMA 2 makes a lot of sense. A nimble, transparent, and customizable model that is free to use could help companies create AI products and services faster than they could with a big, sophisticated proprietary model like OpenAI’s GPT-4.

By allowing the wider AI community to download the model and tweak it, Meta could help to make it safer and more efficient. And crucially, it could demonstrate the benefits of transparency over secrecy when it comes to the inner workings of AI models—at a point when that could not be more timely, or more important.

The big story

This company is about to grow new organs in a person for the first time

August 2022

In the coming weeks, a volunteer in Boston, Massachusetts, will be the first to trial a new treatment that could end up creating a second liver in their body. And that’s just the beginning—in the months that follow, other volunteers will test doses that could leave them with up to six livers in their bodies.

The company behind the treatment, LyGenesis, hopes to save people with devastating liver diseases who are not eligible for transplants. Their approach is to inject liver cells from a donor into the lymph nodes of sick recipients, which can give rise to entirely new miniature organs. 

These mini livers should help compensate for an existing diseased one. The approach appears to work in mice, pigs, and dogs. Now we’ll find out if it works in people. Read the full story.
