Shut down on 2026-09-24, so every call fails.\n\n**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.\n\n## Before you call either\n\n### OpenAI Sora API\n\n1. Don't call /v1/videos. The Videos API was removed on 2026-09-24\n2. Remove `sora-2`, `sora-2-pro` and the dated snapshots from configs and fallback chains\n3. Pick another provider from this category. OpenAI has no video model on its API now\n\n### Seedance on BytePlus ModelArk\n\n1. 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\n2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads\n3. 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\n4. 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\n5. 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\n\n## Questions\n\n### Which is better for AI agents, OpenAI Sora API or Seedance on BytePlus ModelArk?\n\nSeedance on BytePlus ModelArk scores 59.3 (C) on agent readiness against OpenAI Sora API's 9.4 (F), and leads in 6 of 7 scored categories.\n\n### Do OpenAI Sora API and Seedance on BytePlus ModelArk need an API key?\n\nBoth need an API key.\n\n### Can an agent call OpenAI Sora API and Seedance on BytePlus ModelArk without installing anything?\n\nYes. OpenAI Sora API has a hosted endpoint at https://api.openai.com/v1 and Seedance on BytePlus ModelArk at https://ark.ap-southeast.bytepluses.com/api/v3.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/openai-sora-vs-seedance-on-byteplus-modelark.json, and with the fewest tokens: https://www.anchorterminal.com/compare/openai-sora-vs-seedance-on-byteplus-modelark.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"openai-sora\", \"b\": \"seedance-on-byteplus-modelark\"}`.
