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

Anthropic's most advanced AI model is facing adoption challenges as cheaper alternatives gain traction in the market. While Anthropic's revenue grew significantly to $65 billion annualized by July 2026, data from the Ramp AI index (which tracks AI model spending across 70,000 companies) shows that users are gravitating toward older, less expensive Anthropic models like Opus 4.8 rather than the newest Opus 5 released in July.
