Wait, doesn’t the blog post say the price is the same as 4.7?

> Claude Opus 4.8 is available everywhere today. Pricing for regular usage is unchanged from Opus 4.7: $5 per million input tokens and $25 per million output tokens. Pricing for fast mode is $10 per million input tokens and $50 per million output tokens.

Where do you see the 2x cost?

The total cost of running my benchmarks, was 1.6x higher compared to Opus 4.7, mostly because of 2x output tokens:

If it spends 2x tokens to achieve the same result, that's effective 2x cost in a manner of speaking
