API Updates

1. Sora 2 duration

   • Sora 2 now generates 15-second videos.
   • Watermarked and watermark-free are two separate price tiers; the pricing page is the source of truth for current rates.
2. Platform updates

   • Webhook: callback parameters are now supported.
   • Website: pages are available in multiple languages, no browser translation plugin needed.
3. Veo 3 sunset notice

   • Nearly all traffic has moved to veo3.1-fast, so the legacy Veo 3 will be retired in 3 days.
   • If you still call it, change the model parameter to "veo3.1-fast".

1. New channel

   • A new channel that passed our stability tests is now serving Veo 3.1.
2. Smart routing

   • The system picks an available channel automatically; callers do not need to change anything.
   • If the preferred channel is unavailable, traffic switches to a backup channel to preserve stability.
3. Next steps

   • We keep evaluating and onboarding channels that are both stable and cost-effective.

2. Channels and roadmap

   • The channel in use is stable and matches official capability.
   • Extended-length video (video extension) is in integration testing and will open once it meets our bar.

1. Why this model

   • Direct official channel: stable, low latency, no quality degradation, multimodal input supported.
   • Docs: Gemini 2.5 Pro quickstart
2. Concurrent promotion

   • wan 2.5 video, wan 2.5 image and Qwen Image Edit are on a limited-time promotional rate.
   • The promotion is time-limited and we will give notice before it ends; the pricing page is the source of truth for current rates.

1. Parameter support

   • remove_watermark controls the watermark: true removes it, false keeps it.
   • The parameter defaults to true: omit it and the request is treated as the watermark-free version, which affects billing.
2. Billing

   • Watermark-free and watermarked are two separate price tiers; the pricing page is the source of truth for current rates.
   • See the latest Sora 2 docs for details.

• Platform pricing has been updated. The pricing page and the individual model pages are the source of truth for current rates.
• Sora 2 will move to tiered pricing based on generation parameters (duration, resolution); parameters and rates are updated together on the model page.
• If upstream providers or channels force a change, we will announce it in advance.

• Added horizontal screen and vertical screen parameter selection to support different screen ratios.
• Supports uploading reference images, please see the document for specific parameters and calling methods: Sora 2 Document

Risk control tips (reference picture)

• OpenAI official review of reference images is extremely strict.
• Reference pictures containing real-life photos are likely to fail in the review. It is recommended to give priority to non-real-life pictures such as animations, landscapes, and concept pictures to increase the success rate.

• Sora channels are fully restored; the earlier instability has been traced and fixed.
• From October 5, Sora moves to regular billing. The pricing page is the source of truth for current rates.
• We will keep improving the interface based on what we learned over the past few days, for better stability and experience.

• The Sora 2 API is now open. If you already call another video model, switching to Sora 2 takes minutes — see the Sora 2 docs.
• Note: Sora 2 takes about 5 minutes to generate; leave enough headroom in your business logic.
• The pricing page is the source of truth for current rates.

Sora 2 stability and content filtering

• Overnight monitoring put the Sora success rate around 88.24%; channels overall are still limited by the lack of an officially stable upstream interface.
• Current failures concentrate in content moderation. Sora filters aggressively — prompts with mild sexual or horror elements fail easily.
• Refine your prompts; if the failure rate stays high after ruling out moderation, contact us and we will help investigate.
