This simple change stops robot swarms from getting stuck

In crowded environments, more robots don’t always mean faster results—in fact, too many can bring everything to a standstill. Harvard researchers discovered a surprising fix: adding a bit of randomness to how robots move can actually prevent gridlock and boost efficiency. By allowing robots to “wiggle” slightly instead of marching in straight lines, they can slip past each other and keep tasks flowing smoothly.

OpenAI expands its cyber defense program with GPT-5.4-Cyber for vetted researchers

Defending critical software has long depended on the ability to find and fix vulnerabilities faster than attackers can exploit them. OpenAI is expanding a program designed to give professional defenders prioritized access to AI tools built for that purpose. The company is scaling its Trusted Access for Cyber (TAC) program to thousands of verified individual defenders and hundreds of teams responsible for defending critical software. Alongside that expansion, OpenAI is releasing GPT-5.4-Cyber, a version of … More → The post OpenAI expands its cyber defense program with GPT-5.4-Cyber for vetted researchers appeared first on Help Net Security.
