I agree that Opus almost definitely isn't anywhere near that big, but AWS throughput might not be a great way to measure model size.

According to OpenRouter, AWS serves the latest Opus and Sonnet at roughly the same speed. It's likely that they simply allocate hardware differently per model.

The numbers look about right. Opus 4.5 is about 1.5x the size of Sonnet 4.6, and Opus 4/4.1 is about 5x the size of Sonnet 4.5/4.6.

Note that Opus 4.5 is about 1/3 the size of Opus 4/4.1 (and 1/3 the price in the API)
