A startup claims it broke through a bottleneck that\u2019s holding back LLMs<\/strong><\/h3>\n

AI startup Subquadratic came out of stealth last month with a huge claim: it had solved a mathematical bottleneck that had held back large language models for almost a decade.<\/p>\n

The purported breakthrough comes from slashing the number of computations transformers need to carry out to generate answers. The result is a faster and cheaper LLM that uses far less energy than any other model on the market.<\/p>\n

Many experts remained skeptical\u2014but Subquadratic has started to share the receipts. They suggest that their approach might be worth paying attention to.<\/p>\n

Here\u2019s how the system works\u2014and why some researchers still aren\u2019t convinced<\/a>.<\/p>\n

This week, I covered the story of Casey Harrell<\/a>\u2014a man with ALS who is \u201cthe first power user\u201d of a brain implant. The device has enabled him to maintain an income, reconnect with friends and family, and read to his daughter. He told me that it\u2019s \u201cnothing short of revolutionary.\u201d\u00a0<\/p>\n

Over the past couple of years, the number of BCI trial volunteers has soared. This year, China became the first country to approve a BCI for medical use. Advances in technology are allowing engineers to provide more features than ever. BCI research is properly taking off.<\/p>\n

Powerful technologies like genetic modification can create stronger local agriculture and a healthier food system\u2014but they normally aren\u2019t. The challenge is ensuring they serve food security and human well-being, rather than simply maximizing profits.<\/p>\n
