Anthropic's Fable 5 Struggles as Businesses Choose Cheaper AI Models

Anthropic's most powerful artificial intelligence model, Fable 5, is failing to gain expected traction among corporate customers, with businesses largely rejecting the expensive flagship system in favor of cheaper, more efficient alternatives. According to spending data from 70,000 U.S. companies analyzed by payments firm Ramp, spending on Fable 5 constitutes approximately 11% of Anthropics total model revenue, a figure that has plateaued more than two months after its launch. This represents a significant shift from previous market behavior, where enterprise customers typically adopted the most advanced models made available by AI labs.
