+OpenNebula offers a range of subscriptions and extensions to suit various operational and business requirements. Organizations can choose subscription models that provide support, maintenance, and access to additional software extensions. 
+
+* **EE** - Refers to features that are Enterprise Extensions and are only available to customers with an Enterprise Subscription
+* **AE** - Refers to features that are AI Factory Extensions and are only available to customers with an AI Factory Subscription
+* **CE** - Refers to the Community Edition, available to all users
+
+Refer to the [OpenNebula website](https://opennebula.io/enterprise-services/#subscriptions) for further information about subscriptions and commercial services.
+
+## OpenNebula Community Edition
+
+When a new OpenNebula major or minor version is released, it is immediately available to everyone and is considered the **Community Edition**. This edition provides the complete OpenNebula core platform, allowing organizations to build and operate private, hybrid, edge, and sovereign cloud environments.
+
+Community Edition users have access to the latest OpenNebula releases and the full set of features included in the core platform.
+
+## OpenNebula Enterprise Edition
+
+The **Enterprise Edition** is available to **Enterprise Subscription** customers. The Enterprise Edition and the Community Edition share the same source code and OpenNebula maintains a single software distribution. Enterprise subscription customers have access to the following additional features and services:
+
+* **Maintenance Updates**: Delivered through Enterprise channels, maintenance releases include minor enhancements, bug fixes, software patches and stability improvements. Maintenance updates do not introduce significant new features and functionality. 
+* **Enterprise Extensions**: Software extensions that expand the capabilities of OpenNebula for production-grade cloud deployments. These extensions are delivered, installed and maintained independently from the main OpenNebula distribution.
+* **SLA-based Support and Professional Services**: Enterprise customers are provided with secure, private support under a commercial SLA and access to OpenNebula Systems’ Professional Services for expert assistance with cloud deployment and maintenance.
+
+## AI Factory Subscription
+
+The **AI Factory Subscription** follows the same model as the Enterprise Subscription. It uses the same OpenNebula core platform and includes all Enterprise Edition benefits, while adding access to AI-specific extensions and support for AI infrastructure deployments.
+An AI Factory Subscription includes:
+
+* Access to Enterprise maintenance releases
+* Professional support and SLAs
+* Access to Enterprise Extensions
+* Access to **AI Factory Extensions**
+
+AI Factory Extensions are also delivered separately from the OpenNebula core platform through Enterprise channels and are installed independently. The extensions provide advanced capabilities for GPU-accelerated infrastructure, AI Clusters, and large-scale AI Factory deployments.
