 Multimodality refers to a model's ability to simultaneously understand and process information from various sources, including text, images, audio, and other data formats.
-Presently, the OpenAI `gpt-4-visual-preview` model offers multimodal support. Refer to the link:https://platform.openai.com/docs/guides/vision[Vision] guide for more information.
+Presently, the OpenAI `gpt-4-visual-preview` and `gpt-4o` models offers multimodal support.
+Refer to the link:https://platform.openai.com/docs/guides/vision[Vision] guide for more information.
 
 The OpenAI link:https://platform.openai.com/docs/api-reference/chat/create#chat-create-messages[User Message API] can incorporate a list of base64-encoded images or image urls with the message.
 Spring AI’s link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-core/src/main/java/org/springframework/ai/chat/messages/Message.java[Message] interface facilitates multimodal AI models by introducing the link:https://github.com/spring-projects/spring-ai/blob/main/spring-ai-core/src/main/java/org/springframework/ai/chat/messages/Media.java[Media] type.
 This type encompasses data and details regarding media attachments in messages, utilizing Spring’s `org.springframework.util.MimeType` and a `java.lang.Object` for the raw media data.
