Together AI expands Fine-Tuning with live metrics, expert LoRA, and early stopping

Together AI expanded its Fine-Tuning service with support for newer open-weight models, live metrics tracking, and finer training controls.

Expert LoRA adapters can be applied to Mixture-of-Experts expert layers, and early stopping keeps the checkpoint with the best validation loss. Dataset previews, sample weights, pre-flight validation, and lower prices on selected models are also included.
