GCP AI Platform pricing is influenced by several key factors:

1. Machine Types: The choice of machine type for training and deployment significantly impacts costs. Different machine types offer varying levels of performance and resources, with corresponding price variations.
2. Accelerators: If you opt to use accelerators like GPUs or TPUs, their cost is separate from the machine type. The number of accelerators and their type will contribute to the overall pricing.
3. Training and Deployment Time: Longer training and deployment times lead to higher costs. It's important to optimize your workflow and model efficiency to minimize these times.
4. Custom Models: If you use custom-trained models, the pricing is calculated based on the combination of machine types and accelerators used during training.
5. Online Predictions: Charges apply for online predictions based on the deployed model. The pricing depends on the chosen machine type and usage duration.
6. Batch Predictions: Similarly, batch predictions come with their own pricing structure based on the machine type and processing time.

GCP AI Platform is not entirely free. While Google Cloud offers certain usage under a free tier, most AI Platform services are paid. The free tier typically covers a limited amount of usage, providing an opportunity to explore the platform's capabilities without incurring charges.

However, for more substantial usage and resource-intensive tasks, charges will apply. It's crucial to monitor your usage and stay within the free tier limits if you wish to avoid costs.
