 This setting redirects requests made with `provider: :openai` to your specified base URL. See the [Working with Models Guide]({% link guides/models.md %}#connecting-to-custom-endpoints--using-unlisted-models) for more details on using custom models with this setting.
 
+## Optional OpenAI Headers
+
+OpenAI supports additional headers for organization and project management:
+
+*   `openai_organization_id`: Specifies the billing organization for API usage when multiple organizations are accessible.
+*   `openai_project_id`: Tracks API usage for a project.
+
+These headers are optional and only need to be set if you want to use organization or project-specific billing.
+
 ## Default Models
 
 These settings determine which models are used by the top-level helper methods (`RubyLLM.chat`, `RubyLLM.embed`, `RubyLLM.paint`) when no specific `model:` argument is provided.
