Proprietary(managed) with Apache-licensed LoRAX/Ludwig adjuncts

The founders created and maintain OSS LoRAX (multi-LoRA serving) and Ludwig, but the Predibase fine-tuning/RFT platform, which is the thing being scored, is proprietary managed SaaS running on Predibase's own cloud or a customer VPC. The OSS sits at the serving and declarative-ML edges. Class corrected from open_core on 2026-07-30. In this ladder open_core means an OSI core with functionality withheld for a paid tier, and there is no open core here, only an open periphery. A repo that exists while the runtime does not ship is source:partial, which the ladder scores 2/source_available. The score itself was already 2.
