New payment data from Ramp suggests that Anthropic’s most advanced AI model, Fable 5, has had a slow start among enterprise customers, [the Financial Times](https://www.ft.com/content/5ee49718-c258-4f01-aa32-7e5b76ae5245) reports.

Two months after launch, Fable 5 accounts for about 11% of total enterprise spending on Anthropic models, breaking the previous trend of customers quickly moving to the most powerful model.

According to analysts and investors, the development is mainly due to Fable 5’s high price and the fact that cheaper models are good enough for most tasks.

For example, Anthropic’s smaller, cheaper Opus 5 model has surpassed Fable 5 in enterprise spending since its launch in late July. Anthropic itself has declined to comment on the data.
