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

It does work out to be a similar cost per task though
5.5 is higher for max effort, slightly higher for xhigh and lower for high, medium and low effort.
The biggest proportional difference seems to be at max (5.5 is 38% more) and at high (5.5 is 21% less).
I think most people run at high and xhigh. At xhigh it is close enough to be task dependent and I don't think most people will notice. At high effort I think it looks like it will be an improvement for most people.
5.5 Max should probably be compared to Fable - it performs a lot better than 5 Max.
