 The framework-neutral SDK artifacts require Java 8 or later. Runtime floors and lifecycle states
 are declared per artifact in the [Java version support policy](docs/version-support-policy.md).
 
+### Java Platform Module System
+
+The published artifacts are not modular JARs, but each one declares a stable `Automatic-Module-Name`
+so it can be placed on the module path:
+
+| Artifact | Module name |
+| --- | --- |
+| `openai-java` | `com.openai` |
+| `openai-java-core` | `com.openai.core` |
+| `openai-java-client-okhttp` | `com.openai.client.okhttp` |
+| `openai-java-bedrock` | `com.openai.bedrock` |
+
+Each package is contained in exactly one artifact, so these modules can be resolved together on the
+module path.
