On Valentine’s Day, February 14, 2026, the other sideByteDanceWe choose this romantic day to officially release the latest masterpiece of our large language model series:Bean bag 2.0(Doubao-Seed-2.0). This release is not a single model, but a complete product line covering four different positionings: flagshipbean bag 2.0 Pro, the lightweight and efficient Bean Bag 2.0 Lite, the mini version of the Bean Bag 2.0 Mini, and the Bean Bag 2.0 Code specially designed for program development.
ByteDance Beanbao 2.0: Inference cost reduced by an order of magnitude, multi-modal capabilities dominate the industry
Pro version benchmarks against top models: Dominates all benchmark tests
As the flagship of the series, Beanbao 2.0 Pro’s performance targets are directly aimed at the industry’s top GPT-5.2 and Gemini 3 Pro. Judging from the official benchmark test results, this model does have the ability to compete with it. In terms of visual understanding capabilities, Beanbao 2.0 Pro reaches the SOTA (State of the Art, the highest in the industry) level in industry standard benchmark tests. In terms of competition questions that test logical reasoning and mathematical abilities, this model has won gold medals in IMO (International Mathematical Olympia), CMO (Chinese Mathematical Olympia) and ICPC (International College Programming Competition), showing strong logical deduction and problem-solving abilities.
In the SuperGPQA test of knowledge question and answer capabilities, Doubao 2.0 Pro’s score exceeded GPT-5.2; it even won first place in the HealthBench evaluation in the health and medical field. It is particularly worth mentioning that in HLE-text (Humanity’s Last Exam), which is known as the most difficult AI benchmark test, Doubao 2.0 Pro achieved a score of 54.2 points, setting a record for the highest score in this test.
Multimodal capabilities: dynamic scene understanding and long video analysis
In addition to pure text and reasoning capabilities, Doubao 2.0 also shows top strength in the multi-modal field. In the TVBench test of dynamic scene understanding, Doubao 2.0 leads other models in the industry; in the EgoTempo benchmark test, its performance even exceeds human scores. This means that the model can accurately understand the temporal sequence and action logic in first-person perspective videos, which is of great significance for future AR/VR applications.
In terms of long video understanding, Doubao 2.0 also surpasses other top models. This capability is critical for applications that require analyzing movies, surveillance images, or educational videos—the model can not only remember content over long time spans, but also understand cause-and-effect relationships and plot development.
Highly competitive pricing strategy: cost reduced by an order of magnitude
If performance is the hard power of Doubao 2.0, then its pricing strategy is the most lethal market weapon. Through the Volcano Engine platform, ByteDance opens Doubao 2.0 API services to enterprises and developers, and the price setting can be described as extremely aggressive. Doubao 2.0 Pro (32k input version) is priced at only 3.2 yuan per million tokens for input and 16 yuan per million tokens for output. As for the lightweight version of Doubao 2.0 Lite, the input price is as low as only 0.6 yuan per million tokens.
This pricing level is about an order of magnitude lower than other mainstream models in the industry. For enterprise customers and developers who need to call a large number of APIs, this cost advantage is extremely attractive (of course, provided you don’t care that it is a Chinese model).
Commercial implementation: from App to enterprise services
Doubao 2.0 Pro has been fully integrated into the “expert” mode of Doubao App, PC and web version, allowing ordinary consumers to immediately experience flagship AI capabilities. For program developers, Doubao 2.0 Code has been integrated into ByteDance’s AI programming product TRAE. TRAE is a free AI IDE (Integrated Development Environment) launched by ByteDance, which directly targets the popular Cursor in the market. It currently has 1 million monthly active users. By embedding Doubao 2.0 Code into TRAE, ByteDance is creating a one-stop solution from models to development tools.
In terms of enterprise application scenarios, the intelligent customer service agent based on Doubao 2.0 Pro has been implemented on the Feishu platform. This system can use different skills to complete customer conversations, proactively recruit real colleagues for help when necessary, and can also assist customers in making appointments for on-site repair services, and proactively return visits and recommend related products after repairs.
Innovative application scenarios: AI NPC at the Spring Festival Temple Fair
The application of Doubao 2.0 is not limited to the tool level, but also extends to entertainment and interactive experiences. Launched by TRAESpring Festival Town·Year of the Horse Temple Fair“In the project, the development team created 11 NPCs (non-player characters) driven by large language models. These AI NPCs can naturally chat with players, greet customers, and even bargain on the spot, creating an unprecedented interactive experience. Such applications demonstrate the huge potential of multi-modal large models in games and virtual worlds: future video games may no longer need to write complex dialogue scripts, but instead allow AI characters to autonomously generate personalized responses.
In terms of other application scenarios, Doubao 2.0 supports functions such as real-time video stream analysis, environment awareness, active error correction, and emotional companionship. Whether it’s fitness guidance, outfit suggestions, or simple emotional companionship, this model can provide a smooth interactive experience.
summary
The release of Doubao 2.0 marks an important milestone in the technical capabilities and commercialization process of China’s large language model. Judging from the benchmark test results, Doubao 2.0 Pro is already capable of competing head-on with top models such as GPT-5.2 and Gemini 3 Pro, and even takes the lead in certain areas. What is even more disruptive is its pricing strategy: reducing API costs to one-tenth of the industry average. This is not only a price war, but also a fundamental reconstruction of the AI business model. When the cost of model calling is no longer the main bottleneck, more innovative applications will spring up, and the popularity of AI will also be greatly accelerated. ByteDance clearly understands the essence of the “platform economy”: first build an ecosystem at a low price, and then create long-term value from the ecosystem.
However, technical capabilities and price advantages are only the starting point. In implementation cases such as TRAE, Feishu Intelligent Customer Service, and Spring Festival Temple Fair NPC, it can be seen that ByteDance is actively exploring the “killer application” of AI. After all, the ultimate value of a model does not lie in the number of parameters or benchmark scores, but in whether it can truly solve problems and create experiences. The release of Doubao 2.0 may be the turning point for AI from a “technical competition” to an “application competition”.
