A verification loop 4x'd DeepSeek's intelligence, matching Opus at 1/7 the cost

From what I understood, the gist of it is that uses a bunch of skills in a loop to help LLMs solve the tasks better via browser-testing, debugging, visual-testing, etc..

The skills can be found here:

Question that was left unanswered:

How much longer does a 4x DeepSkeep loop took compared to Opus?

Seems interesting, but buried under a mountain of written slop.
