You get a banner in the 2560 x 1440 format with the text kept in the central area that shows on phones, computers and TVs.\n\nChatGPT tells you what the design needs and makes it in your MegaScenes account when you ask. The banner opens in the chat and stays in your library.\n\nFor new channels, rebrands, seasons and launches.\n\nLimitations: your text is passed to the model as written and the lettering is drawn by the model, so check it in the result. It does not upload the banner to your channel. Making a file needs a signed-in MegaScenes account and runs in it; nothing is made until you confirm. Not for sexual or adult content or for real people's likeness. Files are made by generative models and saved in your MegaScenes library.",
