Fable 5 Plateaus at 11% of Anthropic Spend as Opus 5 Overtakes It

Spending data from Ramp covering 70,000 businesses shows Anthropic's Fable 5 has captured 11.4% of Anthropic's enterprise dollar spend and about 6% of tokens, more than two months after its launch. Claude Opus 5, launched in late July at a lower price point, has surpassed Fable 5 in enterprise spending within that period. Fable 5 costs approximately $10 per million input tokens and $50 per million output tokens, roughly twice the price of GPT-5.6 Sol and roughly twice that of Opus 5. Ramp economist Ara Kharazian interprets the low uptake as enterprises not finding the extra performance worth the extra cost. A 30-day data-retention requirement has also been cited alongside pricing as an adoption drag. OpenAI's GPT-5.6 Sol, by comparison, captured 25% of OpenAI tokens and 23% of OpenAI spending; Fable 5 brought in roughly 75% of the model-related revenue GPT-5.6 Sol generated despite costing more per token. Vercel's AI Gateway data puts Fable at roughly 13.2% of model spend across providers in a developer-heavy sample, consistent in direction with the Ramp figures. Finance teams imposing per-employee monthly spend caps are reported to be pushing automated routing toward cheaper models, with more expensive ones reserved for escalations.
