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

Financial data regarding major artificial intelligence companies shows significant revenue growth alongside shifting user preferences for specific AI models. Anthropic reached an annualized revenue of sixty-five billion dollars in July, an increase from forty-seven billion dollars in May. The company also reported to investors that it maintained six thousand customers spending one hundred thousand dollars or more annually, and it projected third-quarter profitability following a profitable second quarter. Meanwhile, rival company OpenAI reached an annualized revenue of over forty billion dollars, driven by a thirty-five percent quarterly jump following the July launch of its GPT 5.6 model.

Billing data from seventy thousand companies using Ramp credit cards provides insight into how customers spend money across different Anthropic AI models. The resulting Ramp AI index shows that older and less expensive models retain strong user spending, while newer models face slower adoption. For July, the model Opus 4.8 accounted for twenty-eight percent of Anthropic model spend, while Sonnet 4.6 captured 8.3 percent and Fable 5 drew eight percent. Newer releases like Opus 5 accounted for just 3.5 percent of spending, partly because it was released late in the month, while the high cost of models like Fable 5 contributed to lower overall popularity among users.
