No, Opus cannot be 10x larger than the chinese models.
replyIf Opus was 10x larger than the chinese models, then Google Vertex/Amazon Bedrock would serve it 10x slower than Deepseek/Kimi/etc.
That's not the case. They're in the same order of magnitude of speed.
They serve it about 2x slower. So it must have about 2x the active parameters.
replyIt could still be 10x larger overall, though that would not make it 10x more expensive.
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.
replyAccording 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.
GPT-4 was likely much larger than any of the SOTA models we have today, at least in terms of active parameters. Sparse models are the new standard, and the price drop that came with Opus 4.5 made it fairly obvious that Anthropic are not an exception.
