If you are not self-hosting on your hardware inside your network, why do you care whether the model is open or not?
In theory if your provider raised rates you could switch providers with an open model. So price competition would be one reason.
because vendors stop serving models and it is good to be able to choose to self host for any reason at any time
we can start out with the hosted version for evaluation and then self host for production and real customers
This model would be self hostable quite easily (~$14k hardware investment) if it’s released as open weights, since the base model is GLM 5.3-Flash. If not, it’s completely DOA for legal use.
