summary: "Corporate users are prioritizing cost efficiency over maximum model intelligence when selecting AI tools for enterprise deployment. Spending on Anthropic's top-tier model, Fable 5, has plateaued at 11% of overall outlay according to data from payments group Ramp. Concurrently, open-weight models captured 62% of tokens on Vercel AI Gateway in August, a significant increase from 28.4% in June. Fable 5 accounts for 6% of purchased tokens and costs twice as much as Claude Opus 5. A forced withdrawal of Fable 5 in June damaged its pricing power and encouraged customers to qualify alternative models to reduce switching costs. Anthropic reports that the newer Opus 5 is within 0.5% of Fable 5's performance on CursorBench 3.2 while costing half as much per task. Despite the shift toward cheaper models, Anthropic's annualised revenue rose to $65 billion in July from $47 billion in May."
