# Are there extra fees for serving trained models?

> How Fireworks bills for serving trained LoRA models on dedicated deployments, including per-GPU-second hosting costs, training fees, and inference charges.

Trained (LoRA) models require a dedicated deployment to serve. Here's what you need to know:

**What you pay for**:

* **Deployment costs** on a per-GPU-second basis for hosting the model
* **The training process** itself, if applicable

**Deployment options**:

* **Live-merge deployment**: Deploy your LoRA model with weights merged into the base model for optimal performance
* **Multi-LoRA deployment**: Deploy up to 100 LoRA models as addons on a single base model deployment
