I have a strong feeling that lite is Qwen 3.5 27B and Max is GLM 5.2, based on the AAII scores on protons announcement post. 27B thinking is closest to 34 AAII and only GLM hits 51. So as fingerprints go....
But the fact that Lumo won't reveal specifics / inhibits that at system prompt level (despite broad family id being cooked into weights) sort of belies the transparency angle for me. What else is being obfuscated? I can't even uncover what fair use is - how many messages per hour etc
Logical inference then - opacity is driven by profit margin preservation and competitive insulation. If you can't calculate the mark up by query (vs OR) then you might be paying 5-20x mark up.
Sits funny amidst all the privacy and transparency cosplay.
At least they're not building autonomous weapons but treating open weight models as commercial secrets is sorta off putting.
