What

Remove seedance-1-5-pro-251215 (Seedance 1.5 Pro) from the BytePlus videos catalog.

Why

BytePlus shut down seedance-1-5-pro-251215 after 17:00 on November 11, 2026 (UTC+8) with no automated replacement, and a live call made after that time is rejected.

Evidence

  • seedance-1-5-pro-251215 shut down after 17:00 on November 11, 2026 (UTC+8), not migrated automatically, recommended replacement dreamina-seedance-2-0-mini-260615: Model deprecations, Model list
  • Video generation is served only from ap-southeast-1, the host Celeste calls (the EU region lists only the Chat and Image generation APIs): Region availability
  • 400 with the InvalidEndpoint.ClosedEndpoint message, "The request targeted an endpoint that is currently closed or temporarily unavailable": ModelArk error codes
  • duration 4 and resolution 480p are the shortest and lowest values for Seedance 1.5 pro: Create video generation task API

Files

  • src/celeste/modalities/videos/providers/byteplus/models.py

Validation

make ci: pass
Live call: made (BytePlusVideosClient.generate(prompt="A cat walking", duration=4, resolution="480p") on seedance-1-5-pro-251215 at 2026-11-11 11:32 UTC; POST /api/v3/contents/generations/tasks returned 400 "The request targeted an endpoint that is currently closed or temporarily unavailable.")
