The 15 most important things happening in AI today, sourced from blogs, Substacks, and researchers who matter.
1. Claude Fable 5: Anthropic’s Most Powerful Model Comes With Controversial Restrictions
Anthropic released Claude Fable 5, its first Mythos-class model, which dominates benchmarks (95% on SWE-bench) but costs 2x more than Opus and aggressively filters ~9% of requests with new mandatory data retention policies. This signals a major shift toward power and safety trade-offs that will reshape how enterprises build with frontier models.
