fable5

On August 24, according to the Financial Times, Anthropic's U.S. corporate clients are reducing their use of its most powerful model, Fable5, opting instead for lower-priced alternative models, raising concerns about its high-investment business model. Anthropic is currently preparing for an IPO, with the market expecting its valuation to reach $2 trillion or more, potentially listing as early as September.Data from Ramp on spending by 70,000 companies shows that two months after the release of Fable5, corporate spending on this model accounted for only about 11% of Anthropic's total tool spending, and has recently stabilized. Analysts believe the main reason is that Fable5 is expensive, while older models can meet the needs of most companies; the Opus5 launched at the end of July is smaller and cheaper, with corporate spending already exceeding that of Fable5. Fable5 was withdrawn shortly after its release in early June due to intervention by the Trump administration on national security grounds, and was allowed to go back online on July 1, but demand and adoption rates remain lower than those of previous cutting-edge models.Anthropic's annualized revenue reached $65 billion last month, up from $47 billion in May, growing nearly sevenfold since the beginning of the year; the company achieved adjusted operating profit for the first time in the second quarter and has 6,000 clients with annual spending exceeding $100,000. Companies are controlling AI spending by choosing models with better cost-performance ratios, while OpenAI has seen a rebound, with annualized revenue growing 35% this quarter after the release of GPT5.6, exceeding $40 billion. The market is shifting from "chasing the strongest model" to placing greater emphasis on a comprehensive balance of model capability, price, and actual ROI.
