音画不同步是AI视频的另一大顽疾。Seedance 2.0利用其底层的Seed 2.0大模型，通过一种被称为“双分支扩散变换器”的架构，实现了原生视频与音频（包括对白、音效、环境声）在同一生成过程中的精确同步。
这是月之暗面“模型即Agent”的逻辑。目前，绝大多数Agent产品的智能上限仍由模型能力决定，只有拥有强大、可控、具有上下文和复杂推理能力的自研基座模型，才能支撑起用户理想中的“Agent”，而这也更符合Kimi长期聚焦长文本的优势。

As part of its Amazon partnership, OpenAI plans to develop a new “stateful runtime environment” where OpenAI models will run on Amazon’s Bedrock platform. The company will also expand its previously announced AWS partnership, which committed $38 billion in compute services, by $100 billion. OpenAI has committed to consuming at least 2GW of AWS Tranium compute as part of the deal, and also plans to build custom models to support Amazon consumer products.
