Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time SSE responses, or "stream": false for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Instagram Grid Strategy

Color cohesion — maintain the same 3-4 colors across your grid for visual harmony
Alternating patterns — rotate between close-ups, wide shots, and graphic posts
Portrait posts (4:5) take up more feed real estate and get better engagement
Carousel posts have the highest engagement rate — design 5-10 cohesive slides
Consistent editing style — same warmth, contrast, and saturation across all posts
