Finally that price drop
```
   Prices per 1M tokens     Claude Opus 5.5    Claude Opus 5
   Cache reads              $0.20              $0.50
   Input tokens             $4                 $5
   Output tokens            $20                $25
   Cache writes             $5                 $6.25
```
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 is only a price drop if price * tokens used is less

    Happened to be testing a "review patches on a mailing list" harness I was developing; here are a sample of the latest results, testing 12 patches containing a total of 14 issues:
    Opus 5.5: Found 8/14 issues. Total cost: $15.40
    Fable 5.1: Found 7/14 issues. Total cost: $66.34
    Opus 5: Found 6/14 issues. Total cost: $15.19
    Sonnet 5: Found 2/14 issues. Total cost: $19.15
    This is a relatively small sample size, but it was both the best and the cheapest.
    ETA: NB this is "Equivalent API" cost as reported by claude's CLI; I was using my subscription.

    Good data and goes to show that Fable is melting the GPUs and is priced accordingly. I'd guess that cost to serve for Opus 5.5 is meaningfully lower through architecture advances
