+
+![Product Module Diagram](../../buy/images/models.png)
+
+## Getting Started with d.run
+
+After a new user registers for d.run, they first need to [purchase computing power](./buy.md), which supports various options from single cards to thousands of cards. You can check your purchased resources at any time and review your purchase history.
+
+Once your order is effective, the d.run backend will automatically create a [computing cluster](../kpanda/intro/index.md). You can set user, user groups, workspaces, and platform personalization in [Global Management](../ghippo/intro/index.md).
+
+In the [Model Center](../dmc/index.md), you can deploy high-availability large language model services with one click and perform distributed inference through a unified model inference interface. The Model Center supports various popular large models both within and outside the industry, tightly integrated with intelligent Q&A and workflow orchestration modules. You can easily access various online model API Keys and flexibly switch between local and online model services as needed.
+
+Next, use DataTunerX for [model fine-tuning](../dtx/index.md), trying out fine-tuning datasets and hyperparameter groups to achieve automated processing of the entire lifecycle of model fine-tuning, evaluation, and inference. By efficiently utilizing the underlying distributed computing resources in the computing cluster, DataTunerX can conduct matrix-style model fine-tuning experiments, promoting the agility and automated iteration of large models.
+
+After fine-tuning the model, the AI [Process Engine](../monkey/index.md) can create intelligent Q&A systems that generate text from text, images from text, images from images, and videos from text. You can adjust the corpus and GPU resources used by the intelligent Q&A system at any time and quickly respond to user feedback.
+
+Through the AI process, different [intelligent Q&A](../dak/index.md) can be generated for various industries and scenarios, managing the upper and lower levels and front and back-end facilities of intelligent Q&A in a one-stop manner, controlling user demand, and gaining insights into cutting-edge trends.

+
+## Industry Background
+
+The global artificial intelligence industry is experiencing explosive growth, leading to an exponential increase in demand for intelligent computing power.
