Hunyuan-TurboS: Tencent's Fast-Thinking Model for Instant Responses 110

What is Hunyuan-TurboS?

Hunyuan-TurboS is a new-generation fast-thinking model launched by Tencent. Different from slow-thinking models such as Deepseek R1 and Hunyuan T1, which need to "think before replying," Hunyuan-TurboS is capable of "instant replies," with response speed doubled compared to its predecessor and first-token latency reduced by 44%. In terms of pricing, the optimized model enables smooth instant content generation, suitable for a wide range of applications such as knowledge, mathematics, and creative writing. Tencent plans to gradually roll out corresponding product integrations, such as the upcoming grayscale launch of "Tencent Yuanbao."

Features of Hunyuan-TurboS

• Rapid Response: The "instant reply" capability offers a better user experience. Compared to the previous generation, text generation speed is doubled, and first-token response latency is reduced by 44%, making interactions faster and smoother.

• High-Quality Output: While responding quickly, the output content quality remains high. When generating text rapidly, the information is accurate and the logic is clear.

• Strong Across Multiple Domains: It performs excellently in knowledge Q&A, mathematical reasoning, programming code generation, and many other fields, standing on par with top models like DeepSeek V3 and GPT-4o, and even surpassing them in certain aspects.

• Architectural Advantages: The Hybrid-Mamba-Transformer architecture combines Mamba and Transformer, optimizing computational efficiency and memory usage, reducing training and inference costs, and enhancing the ability to handle long sequence texts and complex contextual relationships.

• Diverse Applications: It can be used in everyday conversations, content creation, information queries, educational tutoring, programming assistance, and more, serving different users through the Tencent Cloud API interface and the Tencent Yuanbao application.

• Building an Ecosystem: As the core of the Hunyuan series, it supports the development of derivative models, such as the T1 model that incorporates deep thinking, providing users with a comprehensive ai capability solution.

• Architectural Innovation: Adopting the Hybrid-Mamba-Transformer architecture, it integrates technical advantages, reduces the computational complexity of traditional Transformer models, decreases KV-Cache usage, improves computational efficiency, and lowers deployment costs.

• Cost-Effective Pricing: Turbo S offers competitive pricing at 0.8 yuan per million tokens for input and 2 yuan per million tokens for output, several times cheaper than the previous Hunyuan Turbo model.

• Smarter Inference: Hunyuan Turbo S performs well in mathematics and logical reasoning. Fast thinking enables accurate judgment in a short time, and combined with the advantages of slow-thinking models, it improves overall inference stability and accuracy.

Technical Innovations of Hunyuan-TurboS

• Hybrid-Mamba-Transformer Architecture: Combining Mamba's capability to efficiently process long sequences with Transformer's advantage in capturing complex contexts, it builds a hybrid architecture with optimal memory and computational efficiency.

• Fusion of Long and Short Chain-of-Thought: By introducing long chain-of-thought, retrieval augmentation, and reinforcement learning techniques, it significantly improves science reasoning capability and achieves an overall performance boost for the model.

Application Scenarios of Hunyuan-TurboS

• Social Scenarios: Provides an instant smart assistant in WeChat group chats, with Moments content generation speed approaching that of a real person typing.

• Business Scenarios: E-commerce customer service response times are shortened, and parameter descriptions and sample codes are auto-completed during code development.

• Content Production: When self-media creators use Yuanbao, the time required for the complete workflow from entering topic keywords to generating outlines, image suggestions, and clickbait titles is significantly reduced.

How to Use Hunyuan-TurboS?

• API Calls: Developers and enterprise users can invoke Hunyuan-TurboS via the Tencent Cloud API.

• Tencent Yuanbao: Regular users can select the "Hunyuan" model within Tencent Yuanbao and disable deep thinking to use it.
