Quick Codexometer Bench run, ranking with bias towards lower cost (actually, prioritising for speed doesn’t change the ranking!)

Looks like a win guys! 
(but mainly because of that 50% reduction, though it appears GPT-6-Sol can be faster too)
(NB I reran the failed result for 5.6 Luna and it … failed again, so I’ve let that stand - looks like 6 Luna is a “better” model too)
