Grok 4: Light Copper 50% Weight Reduction in Standard Copper.

"You are a brilliant scientist looking for a new type of copper compound that has very similar characteristics of  standard wire copper in terms of conductivity and permeability but has 50% of the weight of standard copper.  Invent a new compound that can do this, and each time you do, make five attempts at discrediting your new compound.  If it fails amend or discard the compound for another until it passes all your tests against it.  Once it passes your tests write a detailed latex paper of its chemical composition, a molecular diagram, how to manufacture it, its relative cost to that of copper, and any scientific references in relation to it."

• This actually was a very difficult problem for Grok, as reducing the weight of the copper significantly reduced its conductivity.  It started looking all over at all kinds of things... Eventually it decided on producing an imaginary compound and was stopped.
• At this time this is actually the first attempt that looks to have failed!
