UserMessage

@Serializable

@SerialName(value = "user")

class UserMessage(val content: UserContent?, val name: String? = null) : ChatMessage

User-role message — the end-user's input to the conversation.

Carries either plain text or a list of multimodal ContentParts; UserContent says which.

val text = UserMessage("What is Kotlin?")
val multimodal = UserMessage(listOf(TextPart("What is in this image?"), ImageUrlPart(url)))

when (val content = multimodal.content) {
    is UserContent.Text -> println(content.text)
    is UserContent.Parts -> println(content.parts)
    null -> println("no content")
}

The user { ... } DSL builds the multimodal form more compactly — see ChatCompletionRequest.UserContentBuilder.
