[Anthropic's High-Priced AI Model Fable5 Faces Demand Stagnation, Affordable Models Disrupt Industry Norms] According to Deep Tide TechFlow on August 24, citing Sina Finance, demand for Anthropic's flagship high-priced AI model Fable5 has stagnated. Lamp's analysis of AI expenditure data from 70,000 companies shows that in the two months since Fable5's release, corporate spending on this model accounted for only 11% of Anthropic's total model revenue. The *Financial Times* noted that this disruptive shift breaks the industry norm of corporate users prioritizing the most powerful performance models. Analysts and investors believe the core reasons are: Fable5's high pricing and the fact that most business needs can already be met by existing models. If this trend continues, the business model of AI companies investing billions of dollars in training large-parameter, high-complexity models may undergo a fundamental change. Miles Clements, a partner at venture capital firm Accel, which invested $1 billion in Anthropic, stated that the vast majority of users do not need cutting-edge large models, and the era of customers blindly chasing top-tier models is unsustainable. He predicts that achieving high-difficulty goals such as curing diseases will still require breakthrough advancements in AI performance, but high-end large models will increasingly become mere "showcase samples" for demonstrating technical prowess. Lamp's data shows that Anthropic's small-parameter yet high-performance model Opus5, launched at the end of July, has already surpassed Fable5 in corporate spending. Industry insiders revealed that OpenAI's release of ChatGPT 5.6 in July, priced far below Fable5, has gained significant market traction and played a key role in reversing its sluggish performance earlier this year.
