# Create episodic Seedance 2.5 TikTok shorts with GPT-6 and Replicate

> Quick overview This scheduled workflow reads episode and character data from Google Sheets, uses OpenAI to write a 30-second Seedance 2.5 prompt with captions, renders the video on Replicate, and publishes it via SocialRobot to TikTok (draft) with optional posting to Instagram Reels and Threads. How it works 1. Runs every day at 18:00 on a schedule trigger. 2. Reads the Episodes tab in Google Sheets, selects the first episode not marked done/failed, and pulls the most recent completed episode summary for continuity. 3.

Uses OpenAI (GPT-6 Luna) to generate a timed multi-shot Seedance prompt, an episode title, platform-specific captions, and a short episode summary. 5. Submits a Seedance 2.5 reference-to-video job to Replicate, polls until it succeeds/fails/times out, and downloads the resulting MP4. 6. Validates the downloaded video’s
