Anthropic’s best AI model struggles to attract users as cheaper tools thrive
According to an FT story cited by Simon Willison, Anthropic's annualized revenue for July reached $65bn, up from $47bn in May. The company told investors it expects Q3 to be profitable, using the same model that declared Q2 profitable, and reported 6,000 customers spending $100,000 or more annually. Meanwhile, OpenAI's annualized revenue has jumped 35% in the quarter to date, now over $40bn, with the launch of GPT 5.6 in July boosting performance after a sluggish start to the year. The article also introduces the Ramp AI index, which uses billing data from 70,000 companies to estimate model adoption. Ramp's breakdown of Anthropic model spend for July 2026 shows Opus 4.8 leading at 28.0%, followed by Sonnet 4.6 at 8.3%, Fable 5 at 8.0%, Opus 4.6 at 6.9%, Sonnet 5 at 3.6%, and Opus 5 at just 3.5%. This suggests that Opus 5, released on July 24th, has not yet gained significant traction, possibly due to its cost.
Anthropic's newest model, Opus 5, holds only 3.5% of model spend, indicating developers favor cheaper alternatives.
