Predibase

Predibase is a platform for fine-tuning and serving open-source large language models, letting teams customize smaller models for their tasks instead of relying solely on large proprietary APIs. Built by the creators of Ludwig and LoRAX, it makes efficient fine-tuning approaches like LoRA accessible and supports serving many fine-tuned adapters cost-effectively on shared infrastructure.

Predibase targets teams that want the quality of task-specific models with better economics and data control. It provides a declarative fine-tuning interface, managed serving with autoscaling, and the ability to host multiple adapters on a single base model. For companies moving from prompt engineering to owning their models, Predibase offers a practical path to production.
