AI Pioneer Wants Europe to Forge Its Own Nimbler Way Forward

▤ Summary

Sepp Hochreiter advocates a lighter, more energy-efficient approach to AI with xLSTM, a model family that emphasizes selective forgetting instead of processing entire datasets. He argues these nimbler models better fit European firms seeking technological sovereignty and lower compute costs. His lab has spun out two companies—NXAI (where he serves as chief scientist) and Emmi AI—with NXAI raising about €20 million and courting industry partners for vertical AI deployments. Researchers applaud the efficiency focus but raise questions about whether xLSTM can scale to match the performance of much larger generative models on bigger datasets.
