Anthropic’s best AI model struggles to attract users as cheaper tools thrive

This article discusses Anthropic's latest AI model, Fable 5, which struggles to attract users despite being their best model, as cheaper alternatives thrive. It cites FT data showing Anthropic's annualized revenue reached $65bn in July 2026, up from $47bn in May, with Q3 projected profitable. OpenAI's revenue jumped 35% to over $40bn, boosted by GPT 5.6. The article introduces the Ramp AI index, tracking model adoption via billing data from 70,000 companies, revealing Fable 5 holds only 8% of Anthropic's model spend, while older, cheaper Opus 4.8 dominates at 28%. This highlights cost sensitivity in AI adoption.
