Training Diffusion Models with Reinforcement Learning We deployed 100 reinforcement learning (RL)-controlled cars into rush-hour highway traffic to smooth congestion and reduce fuel consumption for everyone. Our goal is to tackle “stop-and-go” waves, those frustrating slowdowns and speedups that usually have no clear cause but lead to congestion and significant energy waste. To train efficient…
AI agents have set the tech industry abuzz. Unlike chatbots, these groundbreaking new systems operate outside of a chat window, navigating multiple applications to execute complex tasks, like scheduling meetings or shopping online, in response to simple user commands. As agents are developed to become more capable, a crucial question emerges: How much control are…
OpenAI says over 400 million people use ChatGPT every week. But how does interacting with it affect us? Does it make us more or less lonely? These are some of the questions OpenAI set out to investigate, in partnership with the MIT Media Lab, in a pair of new studies. They found that only a…
The ability to generate high-quality images quickly is crucial for producing realistic simulated environments that can be used to train self-driving cars to avoid unpredictable hazards, making them safer on real streets. But the generative artificial intelligence techniques increasingly being used to produce such images have drawbacks. One popular type of model, called a diffusion…
As director of the MIT BioMicro Center (BMC), Stuart Levine ’97 wholeheartedly embraces the variety of challenges he tackles each day. One of over 50 core facilities providing shared resources across the Institute, the BMC supplies integrated high-throughput genomics, single-cell and spatial transcriptomic analysis, bioinformatics support, and data management to researchers across MIT. “Every day…
There has never been a more pressing time for food producers to harness technology to tackle the sector’s tough mission. To produce ever more healthy and appealing food for a growing global population in a way that is resilient and affordable, all while minimizing waste and reducing the sector’s environmental impact. From farm to factory,…
Ben Vinson III, president of Howard University, made a compelling call for artificial intelligence to be “developed with wisdom,” as he delivered MIT’s annual Karl Taylor Compton Lecture on campus Monday. The broad-ranging talk posed a series of searching questions about our human ideals and practices, and was anchored in the view that, as Vinson…
Last Wednesday, Google made a somewhat surprising announcement. It launched a version of its AI model, Gemini, that can do things not just in the digital realm of chatbots and internet search but out here in the physical world, via robots. Gemini Robotics fuses the power of large language models with spatial reasoning, allowing you…

I’ve been mulling over something that Will Heaven, our senior editor for AI, pointed out not too long ago: that all the big players…
In 2022, Randall Pietersen, a civil engineer in the U.S. Air Force, set out on a training mission to assess damage at an airfield runway, practicing “base recovery” protocol after a simulated attack. For hours, his team walked over the area in chemical protection gear, radioing in geocoordinates as they documented damage and looked for…
