Limits and supported formats are set by each platform and can change; we keep this table current. A dot means Kadenzo can schedule it; a label notes the limit or format. Instagram allows 20 carousel slides in its own app, but scheduled carousels go through its publishing API, which stops at 10. Telegram’s 4,096 applies to text posts; a caption on a photo or video gets 1,024.
