Fine-tuning lets teams train a LoRA adapter on an open base model using uploaded or managed training data. The product records dataset lineage and provides training metrics, including loss, throughput and GPU telemetry, while a job runs.
The service is for teams adapting a model’s behavior to a task without a full-weight training run. Finished adapters can be evaluated and served through dedicated endpoints or managed deployments.

Fine-tuning trains LoRA adapters on open models using versioned datasets and GPU jobs.
