You've moved goalposts from "they haven't open-sourced the process" to "these are marketing materials by Anthropic".

I think you're right to be skeptical, but they _have_ talked about the process publicly.

And I don't think there's anything there that is not reproducible by outsiders? They have access to the same Opus 4.6 that you and I do; though not having to pay for the tokens certainly helps.

I'm pretty sure if you wanted to burn a couple thousand bucks, you'd reproduce at least some of these findings.

The goal post is the same, reproducible. Talking about a process isn’t reproducible. This entire discussion is why I feel developers are so gullible. You are defending a process that’s entirely opaque and you can’t even use. It’s crazy.
