@Manderljung I think they’ve done this for a while? As in, the Max models are typically closed-weight while the others are mostly open-weight. Would need to double check on this

Turns out they've done this for a while for the max versions of their models. My bad!

Thanks @CFGeek for correcting me

Interesting: looks like the latest Qwen model is not being released open source. Instead available via Alibaba Cloud. Also Together AI.
