Message content format

The content field in messages supports both formats:

• String — plain text value ("content": "Hello")
• Array — structured content parts ("content": [{"type": "text", "text": "Hello"}])

Both formats are fully supported. However, only text content parts are available — image and other multimodal content types are not supported.

Response format

Responses follow the OpenAI Chat Completions response format, including:

• id — unique response identifier
• object — "chat.completion"
• choices — array of completion choices
• usage — token usage statistics

Streaming responses use Server-Sent Events (SSE), matching the OpenAI streaming format.
