On October 28, B.AI announced that ByteDance's Seedance series video generation models have been integrated into the API, with official support for full access. A total of four models have been launched, covering different tiers from flagship to lightweight.Seedance 2.5 focuses on multimodal audio-visual joint generation, with a maximum single duration of 30 seconds, up to 1080p 10-bit, supporting up to 50 reference materials and targeted timestamp editing; Seedance 2.0 emphasizes high-quality output, supporting up to 4K 10-bit with audio-visual synchronization, and allows control of the first and last frames as well as extensions before and after; Seedance 2.0 Fast balances speed and cost, providing quick generation at 480p/720p, suitable for advertising variants and storyboard iterations; Seedance 2.0 Mini meets budget-sensitive creative and prompt testing needs at a lower unit price. Developers can now call the above models through the B.AI API, and are welcome to log in to chat.b.ai/chat to experience it.

ByteDance's Volcano Engine has released the video generation model Seedance 2.5 4K, expanding the previous maximum support of 1080P in Seedance 2.5 to 4K film production. In addition to improving resolution, the new version enhances micro-expressions, subtle movements, and visual details through specialized training.Volcano Engine claims that when referencing generation and video editing, this model can better preserve the clarity, color, and fine text of the original material. Currently, the first batch is only open to 20 film studios and directors worldwide, with approximately 20 works participating in the trial, and the earliest projects are planned to be broadcast on satellite TV in November.

Phoenix Technology reported that on October 19, ByteDance's cloud and AI service platform Volcano Engine launched the Seedance Premium AI Drama Incentive Program, providing financial incentives for premium AI short dramas produced using Seedance and launched on the Hongguo Short Drama App. This program excludes live-action dramas and is only open to AI comics, AI simulated dramas, and other AI-generated forms. The video content of the submitted works must be entirely produced using Seedance, with the usage of Seedance 2.5 accounting for more than 50%, and the generation format through API or tool platforms is not limited.Works must rank within the top 50 AI dramas of the month based on Hongguo's popularity index and pass the review. The applicant can be a company or an individual and must ensure that the information is true and complete. The incentives are divided into three tiers based on monthly rankings: for TOP 1 to TOP 10, 200,000 yuan per work; for TOP 11 to TOP 20, 100,000 yuan per work; for TOP 21 to TOP 50, 50,000 yuan per work. The distribution method is 50% cash plus 50% equivalent vouchers. The vouchers can be chosen by the applicant at the time of registration from three options, including an equivalent Volcano Ark API Token, equivalent "Drama Creation" usage rights, or equivalent "Comic Creation Tool" usage rights. Selected works must cooperate to complete the verification of the work and generation records, and if necessary, submit original generation materials. Those who do not pass the verification or have false declarations will be disqualified from receiving incentives. The deadline for the first phase of the activity is January 31, 2027.

At the 2026 Wonderful and Marvelous Night co-hosted by Douyin and Beijing Satellite TV, the founder of Film Hurricane, Pan Tianhong, demonstrated a world model. This model can generate an explorable virtual environment based on text descriptions, allowing users on-site to roam within the generated scenes and continue inputting commands to modify the visuals.Bloomberg reported in September this year that ByteDance is developing a real-time spatial video model based on the video generation model Seedance, supervised by founder Zhang Yiming, with a potential launch as early as October. Related directions include cloud generation, Pico headsets, and Douyin creator tools. ByteDance has not officially confirmed whether this demonstration is the same product as the project, nor has it disclosed the product name, launch time, or detailed performance data.

The Volcano Engine officially launched the Seedance 2.5 API. Compared to Seedance 2, the new version has significantly improved in areas such as instruction adherence, long narratives, character consistency, realism, lighting and shadow quality, and sound effects. It natively supports 30-second video output, a maximum of 50 multimodal material references, and is compatible with more than a dozen languages.

According to the "Science and Technology Innovation Board Daily," at the 2026 Volcano Engine Force Conference, ByteDance officially released the latest flagship version 2.1Pro of the Doubao large model. Tan Dai, President of Volcano Engine, stated that the model has made breakthroughs in four dimensions: code delivery, long-range Agent tasks, multimodal understanding, and enterprise-level stable operation, possessing stronger engineering delivery capabilities and being capable of handling complex R&D tasks for enterprises. At the conference, ByteDance CEO Liang Rubo also emphasized that the company will focus on enhancing large model capabilities and firmly invest in MaaS (Model as a Service) business.The report pointed out that ByteDance's AI strategic focus is clearly shifting towards enterprise-level services. Currently, the daily token call volume of the Doubao large model has reached 180 trillion, an increase of over 1500 times since its release, and has grown more than 10 times in the past year. However, due to the bottleneck in monetization on the consumer side and high expenses (with daily computing costs reaching tens of millions and daily revenue below one million), ByteDance has accordingly adjusted its resource allocation. Meanwhile, the video generation model Seedance, primarily aimed at the B-end, has validated its commercialization potential, with current annual recurring revenue (ARR) reaching 2 billion dollars, effectively offsetting Doubao's computing costs. In addition, the new version of Seedance will also be the first in the industry to launch a 3D white membrane preview feature.

According to LatePost, ByteDance is adjusting its AI resource allocation strategy, shifting its focus from consumer-facing products like "Doubao" to products that serve enterprise clients. This change is partly influenced by the high operational costs of AI and challenges to existing business models.It is reported that "Doubao" has over 200 million daily active users, but due to the enormous computational costs associated with inference and multimodal capabilities, it incurs daily expenses of tens of millions, while its monetization channels, such as e-commerce, generate less than one million daily. In contrast, ByteDance's video generation model Seedance demonstrates strong profitability. Thanks to its efficient MoE architecture (200 billion parameters) and relatively low reliance on inference computing power, Seedance 2.0 currently has a gross margin of 70%, with the vast majority of its revenue coming from enterprise clients, and its current annual recurring revenue (ARR) has reached 2 billion dollars.Insiders reveal that ByteDance's large model data review team has expanded to over 3,000 people this year, primarily to clean training data for programming models. Meanwhile, the MaaS business of Volcano Engine has also been placed in a more important position, with ByteDance's top management setting a goal to increase revenue tenfold and accelerate international expansion. Additionally, ByteDance executives recently visited Anthropic, which has achieved significant growth in both revenue and valuation through enterprise-level AI programming services, providing a reference for ByteDance's strategic adjustments.

According to IT Home citing The Information, two informed sources stated that TikTok's Chinese parent company ByteDance has suspended its global launch plan for the latest video generation model Seedance 2.0 after a series of copyright disputes with several major Hollywood studios and streaming platforms.The report stated that ByteDance originally planned to launch this new video model to global users in mid-March, but has now suspended the related plans. The report added that ByteDance's legal team is investigating and addressing potential legal issues, and engineers are also increasing protective mechanisms to prevent the model from generating content that may lead to further intellectual property infringements.
