Anthropic's Fable 5, touted as the most powerful AI model, is seeing slow adoption among U.S. companies, accounting for only six percent of Anthropic's token sales. This suggests that corporate willingness to pay for frontier AI may have hit a ceiling, as performance gains do not translate into measurable everyday value for businesses.

Anthropic's most powerful model, Fable 5, is being adopted by enterprises at a rate far below expectations, with data suggesting that the willingness of companies to pay for frontier AI may have hit a ceiling.
According to spending data from fintech company Ramp, Anthropic's flagship model Fable 5 accounted for only 6% of Anthropic's token sales and 11.4% of its total spend in its first month. In contrast, OpenAI's GPT-5.6 Sol accounted for 25% of its token volume and 23% of spend. Despite Fable 5's higher unit price, it generated only about 75% of the revenue of GPT-5.6 Sol.
Ramp notes that its data comes from a proprietary token spend management product, with a sample skewed toward tech companies, and that Fable 5 is primarily used for coding, so actual adoption may be even lower.
This report primarily relies on Ramp's proprietary spending data, which is skewed toward tech companies and is a second-hand source. Actual adoption of Fable 5 may be lower than estimated. All data points are from THE DECODER's report and have not been independently verified.
