Anthropic’s top AI model Fable 5 struggles with corporate adoption: What we know

Anthropic’s flagship AI model Fable 5 has captured only about 11% of the company’s enterprise revenue, according to data from Ramp, as businesses favor cheaper, older models. Analysts attribute the slow adoption to high pricing and sufficient performance of existing alternatives, rather than the political controversy that derailed its launch.

A Tepid Reception for a Flagship Model

Anthropic’s most advanced AI model, Fable 5, is struggling to gain traction among corporate clients, with spending on the model accounting for just 11% of the company’s enterprise revenue, according to data published by fintech firm Ramp and previously reported by the Financial Times. The data, collected from 70,000 businesses, indicates that the older and cheaper Opus 4.8 continues to dominate Anthropic’s commercial sales.

Fable 5 was released in June and marketed by Anthropic as a “declawed” version of Mythos, a highly capable system that had sparked widespread concern in the tech sector. Its public debut was short-lived: within days, the Trump administration, citing an obscure export law, ordered the model blocked to all “foreign persons.” Anthropic was forced to take Fable 5 offline for all customers, and it was only re-released to the public on July 1.

Pricing and Practicality Over Performance

According to a report by the Financial Times, the plateau in adoption is not primarily due to political intrigue or technical shortcomings, but rather economics. Fable 5 is one of the most expensive models on the market, priced at $10 per million input tokens and $50 per million output tokens. Many businesses find that less expensive or free models can handle most of their day-to-day tasks effectively, making the premium for Fable 5 hard to justify.

Analysts and investors said the trend is fueled by Fable’s high price and the fact that older models are functional and efficient enough for the majority of commercial requests. They also noted that breakthroughs in intelligence remain crucial for Anthropic to meet ambitious commitments—such as curing disease—and to attract top researchers, but so far these capabilities have not translated into widespread corporate adoption.

Early Criticism and Legal Challenges

Within hours of its initial release, early users voiced complaints about Fable 5, describing its hyper-sensitive safeguards as making the model “close to unusable” and expressing concern that its steep price pointed toward a future with a permanent underclass of users. On June 15, a class action lawsuit was filed alleging that Anthropic misled customers about token limits on the Claude Max 5x and 20x plans.

Competitive Pressures

The challenges for Fable 5 come as Chinese labs such as Moonshot and Z.ai offer more affordable alternatives, intensifying competition in the AI market. Political uncertainty has become a minor factor in shaping users’ technology choices, according to the Financial Times, with price and performance taking precedence.

Financial Outlook

Despite the rocky start, Anthropic’s overall revenue growth has since recovered from the dip experienced in June following the government’s restriction on Fable 5’s rollout. The company remains on track for what is expected to be the biggest IPO of all time, though questions persist about the sustainability of its capital-intensive model.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
