News Summary

• 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 company at first provided little evidence for its claims beyond a handful of self-published test scores.
• A month on, the company has published more information about its model, including the results of additional independent tests run by third-party firm Appen.
• The results suggest that the company’s claims might be worth paying attention to.
