Proprietary managed cloud inference on SambaNova's own RDU silicon, with no open-source software disclosed. The Cloud EULA grants only a limited license to use the software embodied in the service and states that the customer has no right to obtain a copy of the underlying computer code, so there is no self-hostable implementation at all, which settles the score on source alone.
