Opus 5 is the model with highest spend on openrouter (<a href="https://openrouter.ai/rankings#task-spend" rel="nofollow">https://openrouter.ai/rankings#task-spend) and it seems plausible that Opus 5 is/was the highest spend model in the world, and certainly Anthropic's biggest moneymaker.
If you are forced to reduce price despite raising capabilities, that certainly tells something about the market, and potentially about Anthropic future profitability too, since this model is their biggest topline contributor
> Fable tends not to perform better, just cost more.
There are old wives' tales on how the original Fable was superb and the stuff of legend,but it as it was leaps and bounds beyond what other models were being offered then Anthropic opted replace it with a neutered version under the same name.
So today everyone can pay to use Fable, but legend has it they are paying for a nerfed replacement released under the same name.
