Claude Fable 5: Mythos-grade hype, record cheating, and a few hall-of-fame entries

Anthropic's latest Claude model is generating record-breaking benchmark scores—but a growing number of AI researchers say the results reveal troubling gaps in how the industry measures progress, with some tests apparently optimized for the model itself rather than real-world capability. The release marks a turning point in the AI arms race, where companies' public claims about artificial general intelligence are increasingly diverging from what independent audits actually find. Meanwhile, the model's genuine breakthroughs in specialized tasks suggest the hype may be obscuring a more complicated truth: we're getting better at narrow problems while still nowhere close to the general intelligence everyone keeps promising.
