  • Agent ergonomics, 85 against 64

Watch for

No status page was found on byteplus.com, the docs or the trust centre, and no SLA was found that names ModelArk inference

Verdicts

Google Veo

Audio on every Veo 3.1 clip, up to 4K on Veo 3.1 and Fast. All three Veo 3.1 previews shut down on the Gemini API on 2026-10-22.

Seedance on BytePlus ModelArk

The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

Before you call either

Google Veo

  1. Move off veo-3.1-*-preview before 2026-10-22. Use gemini-omni-1.1-flash on the Gemini API or the GA Veo IDs on Vertex AI
  2. Call predictLongRunning, then poll the operation name about every 10 seconds until done is true. Jobs take 11 seconds to 6 minutes
  3. Download the video within 2 days. The server deletes it after that
  4. Set durationSeconds to 8 for 1080p, 4K or reference images. Shorter clips aren't supported there
  5. In the EU, UK, Switzerland and MENA image-to-video only accepts personGeneration set to allow_adult

Seedance on BytePlus ModelArk

  1. POST to /api/v3/contents/generations/tasks on ark.ap-southeast.bytepluses.com, then poll GET /contents/generations/tasks/{id} or pass callback_url. Callbacks need an answer within 5 seconds
  2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
  3. Pass resolution, ratio and duration in the request body. Parameters appended to the prompt as --rs or --dur are weakly validated and may be ignored
  4. On Seedance 2.5 set omni_reference_task_type to edit or extend so constraint errors arrive at submission. With auto they arrive after the task leaves the queue
  5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
