A startup claims it broke through a bottleneck that’s holding back LLMs
A decade-long bottleneck. Subquadratic just claimed it solved the math problem holding back LLM scaling.
Why it matters
If verified, this could reshape model training efficiency and reduce the compute barrier to entry for frontier labs. The startup's claims about solving a fundamental mathematical constraint would directly impact model development timelines and costs across the industry.

Publisher excerpt: Miami-based AI startup Subquadratic came out of stealth mode last month with a huge claim. It announced that it had solved a mathematical bottleneck that had been holding back large language models for almost a decade. The details were thin, and many people were unconvinced. But Subquadratic has…
