FT: Anthropic’s Fable 5 still holds only about 11% of enterprise spend more than two months after launch

The Financial Times, as cited by BlockTempo, reported that Anthropic’s flagship and most expensive model, Fable 5, has yet to become the default choice for enterprise buyers despite being on the market for more than two months. Data compiled by payments platform Ramp from more than 70,000 businesses showed that Fable 5 accounted for only around 11% of spending on Anthropic tools, with most budgets still going to older, cheaper models. On a token-usage basis, the share was even lower at 6%, while the lower-priced Opus 5, launched in late July, has already overtaken Fable 5 in business spending. The report argues that the pattern challenges the assumption that companies will always pay for the most advanced model available. It also raises questions about the economics behind Anthropic’s heavy investment strategy as the company prepares for a widely watched IPO that investors reportedly think could value it at more than $2 trillion. Even so, Anthropic’s business has continued to expand, with revenue up nearly sevenfold this year, adjusted operating profit turning positive in the second quarter, and 6,000 customers spending at least $100,000 annually.

Leaked Claude model IDs put Anthropic’s Fable 5 adoption problem back in focus

Two unreleased Anthropic model IDs — claude-mashmallow-eap and claude-melon-eap — have surfaced in third-party developer apps and Discord communities, prompting fresh discussion about the company’s product lineup just months after it rolled out Fable 5 as Claude’s top-tier flagship. Early tests circulating online suggest Marshmallow performs better than Melon and may even beat Opus 5 in conversational naturalness, though neither model appears to sit at the same capability tier as Fable 5. Anthropic has not publicly commented on the leak. The timing is drawing as much attention as the models themselves. Data cited in the report shows Fable 5 has struggled to win meaningful enterprise usage despite being Anthropic’s most powerful and most expensive offering. Ramp’s tracking found that one month after launch, Fable 5 accounted for 6% of enterprise token usage on Anthropic and 11.4% of spending. Updated figures obtained by the Financial Times put that spending share at roughly 11% more than two months after release. The report also points to pressure from inside and outside Anthropic’s lineup: Opus 5 reportedly delivers similar benchmark performance at half the price, while Vercel AI Gateway data shows open-source models climbed from 11% of token share in April to 62% in August, while taking less than 4% of enterprise spending.

Musk Says Anthropic Leads AI and Likely Holds a Stronger Unreleased Model

Elon Musk said Anthropic is currently the frontrunner in AI and argued that the company almost certainly has a model stronger than the versions it has already released, one that could be launched at any time. He made the remarks in a long-form interview with Economist editor-in-chief Zanny Minton Beddoes, recorded on July 20 at Tesla’s Texas Gigafactory and aired on July 23. Musk also laid out a concrete AI governance proposal that differs sharply from the framework recently advanced by Google DeepMind CEO Hassabis. His plan calls for top AI firms to hold regular calls every one to two weeks to discuss safety and cybersecurity, and to let rivals test clearly more powerful frontier models through APIs for one to two weeks before release. Government intervention, in his view, should come only if a company is warned about risks and refuses to address them. During the interview, Musk also revisited his criticism of OpenAI, praised Anthropic CEO Dario Amodei in personal terms, discussed the Mythos export-control episode, and repeated a series of long-range predictions on AI capability, work, money, and the broader economy.

Anthropic Unveils Opus 5 AI Model at Half the Price of Fable 5

Anthropic announced the launch of its Opus 5 AI model on July 25, according to BlockBeats. The brief said Opus 5 delivers performance close to Fable 5, which it described as operating at a frontier-intelligence level, while costing only half as much. No additional details were provided in the source about the model’s specifications, release format, target users, or benchmark data. The report was published by BlockBeats as a market analysis item, and the source text did not include further technical or commercial context beyond the pricing and performance comparison.

Leaked Claude Opus 5 sparks early tests as users compare its 3D output with Fable 5

Claude Opus 5 appears to have leaked ahead of launch, and early user tests are already circulating across X and developer tools. Much of the attention is on visual generation quality, especially 3D scenes, interface lighting, Minecraft-style reconstruction and SVG rendering. Users including @chetaslua, @birdabo and @xikhar posted examples that they said showed a visible jump in detail, with some comparisons placing Opus 5 ahead of the already released Fable 5 in scene richness. Separate signs of an upcoming rollout have surfaced since July 9, including a mysterious “Honeycomb EAP” entry in Cursor, an Opus 5 listing reported in Google Vertex AI, and an error dialog that showed the string “claude-opus-5-thinking-high.” A leaked screenshot also appeared to show traffic being routed to Opus 5 after a Fable 5 guardrail was triggered. Even so, no complete and independently verifiable benchmark has been published so far. The idea that Opus 5 could become a cheaper substitute for Fable 5 is gaining traction because Fable 5 is priced at $10 per million input tokens and $50 per million output tokens, which the report says is double Opus pricing. But at least one early tester said Opus 5 burned through tokens extremely quickly, which could erase any apparent pricing edge.
