Today in AI: A look at OpenAI's PPO, social media platforms get 7-day deadline and more

Beyond Q-Star: PPO, the hidden gem in OpenAI's arsenal

Proximal Policy Optimization, or PPO, is helps train computer models to make decisions in complicated or simulated situations.

• PPO is like a personal trainer for computers, especially when they're learning by trial and error. Picture it as a helpful tool to teach machines how to produce text similar to human language.


• The term "Proximal" suggests sticking closely to the original style, and "Policy Optimization" is about finding better strategies. By maintaining proximity to the original style, the improvements made by the programme are steady and reliable.

Humanity needs an OpenAI board that will still say ‘No’

OpenAI’s leadership must think carefully about the remaining board members they add, and not just to look progressive. They need women, people of colour and other diverse voices for whom biased language models are most likely to cause harm, and who will speak up about those risks.

• When OpenAI’s leaders return to work on Monday they’ll have one thing at the top of their to-do list: figure out what to do about the nonprofit board that nearly killed them.


• They’ve already begun setting up a governance structure that will guide them in a more commercial direction, and though that’s great news for OpenAI’s investors, it does fly in the face of its founding principles of prioritizing humanity while building super-intelligent machines.
