Anthropic's Best Model Is 11% of Its Own Bill
The Financial Times ran the number that should worry Anthropic. Ramp, which watches AI spending across roughly 70,000 companies, says that more than two months after launch, Claude Fable 5, Anthropic's flagship, accounts for only about 11 percent of what those companies spend on Anthropic tools. Not 11 percent of the market. 11 percent of Anthropic's own customers' Anthropic spend. The rest goes to cheaper, older Claude models that do most business tasks fine.
The reason is not mysterious. Fable runs $10 to $50 per million tokens in and out. DeepSeek's comparable models sit under $1. That is a 10x to 50x gap for output a lot of people judge close enough. When the difference is that big, the smart move stops being pick the best model and becomes route the task, cheap models for the easy 90 percent, the expensive one only when it actually earns its keep. Enterprises have figured this out, and every routing layer we have covered for the last month, Ramp Router, Stripe buying OpenRouter, HarnessRouter, exists to make that arbitrage automatic.
Here is the uncomfortable part for the labs. The better routing gets, the less traffic the flagship sees, and the flagship is the product they spent the most to build. Anthropic's answer has been the free Fable offer, which critics are already calling a token lock-in trap. The frontier is still moving. It is just that fewer and fewer jobs actually need the frontier, and the market has started voting with its bill. FT has the full report.
