IF you havent written your own harness - you would not understand what you can do when you're writing your own harness . the current set of harnesses - all of them are crap tier. The only clue i can give you - it's not in the model providers interest to have token efficiency - but when you are coding the harness yourself you can shoot for that .
In today's world - and idea stated stated is an idea stolen .
What you're saying is sus. If you have a harness that's a tier above frontier labs' offerings, link to it.
I think it is very much in the first party providers' interest to chase token efficiency, considering that they are offering fixed price monthly plans, and users may go to a competitor when they hit limits.
the only clue you can give... why? because it's just words? plenty of opensource harnesses there that invalidate the conspiracy in your only clue that you can give.
Would you please share some blog posts (non-AI written) where people have tried writing their own harness as a learning path and maybe practically as well? I know I can ask an agent and start, but I want to start that outside an llm really and maybe make them do the heavy lifting once I am ready (have a bit of understanding).
