OpenAI launches GPT-Red as US heat pump adoption surges
▼ Summary
– OpenAI gave MIT Technology Review an exclusive look at a system that automates red-teaming, a safety evaluation that typically requires human testers to find ways to break a system.
– The article discusses the rising popularity of heat pumps in the US, with sales doubling over the past 15 years and outpacing natural-gas furnaces by 32% in early 2026.
– Heat pumps use electricity for heating, are highly efficient, and their sales growth continues despite the expiration of a key tax credit.

OpenAI has unveiled GPT-Red, a new system designed to automate red-teaming, a critical safety evaluation process for software. Traditionally, human testers manually probe a system to uncover every possible way to break or hijack it. This new tool aims to streamline that process, potentially keeping the company ahead of malicious actors. MIT Technology Review received an exclusive first look at the technology.
Meanwhile, despite scorching summer temperatures, heat pump adoption in the US remains surprisingly strong. These electric appliances, known for their exceptional efficiency, have seen their sales double over the past 15 years, according to a recent report. More impressively, they are outpacing traditional natural-gas furnaces by 32% in sales during the first quarter of 2026. This growth is particularly noteworthy because a key federal tax credit for heat pumps has just expired. So, what is driving this sustained popularity? The full story explores the factors behind the continued surge.
