Ramp data shows Fable 5 spending plateau as customers use cheaper Anthropic models

Ramp billing data cited by the Financial Times indicates that Fable 5, launched in June, has plateaued at about 11% of spending on Anthropic tools as U.S. corporate customers shift to cheaper alternatives. The summary says Opus 5 has surpassed Fable 5 in the spending data. The figures describe spending estimates from Ramp data rather than Anthropic's reported revenue or independently audited usage.
