Tencent Unveils Hunyuan Turbo S: A New Contender in AI Speed

Chinese tech giant Tencent has introduced its latest AI model, Hunyuan Turbo S, claiming it outperforms competitors in response speed, particularly DeepSeek's R1 model. Released on March 2, 2025, Hunyuan Turbo S is designed as a "fast-thinking model" capable of near-instant replies within a second 13.

Technical Innovations and Performance

Hunyuan Turbo S employs a novel hybrid-mamba-transformer fusion architecture, which Tencent claims is the first successful application of the Mamba architecture to a super-large Mixture of Experts (MoE) model 34. This innovative approach combines:

  1. Mamba's efficiency in processing long sequences
  2. Transformer's ability to capture complex contextual relationships
  3. Reduced computational complexity and KV-Cache usage

The model reportedly doubles output speed and cuts first-word delay by 44% compared to previous models 5. Tencent asserts that Hunyuan Turbo S matches or exceeds top-tier models in various benchmarks, including:

  • MMLU: 89.5 (slightly above OpenAI's GPT-4o)
  • MATH and AIME2024: Top scores in mathematical reasoning
  • Chinese-SimpleQA: 70.8 (outperforming DeepSeek's 68.0) 5

Market Positioning and Pricing

Tencent has positioned Hunyuan Turbo S competitively in the market:

  • Input API price: 0.8 yuan ($0.11) per million tokens
  • Output price: 2 yuan ($0.28) per million tokens 45

This pricing strategy appears to be a response to the pressure from companies like DeepSeek, which has gained attention for its cost-effective, high-performing models 5.

Implications for the AI Industry

The release of Hunyuan Turbo S intensifies the ongoing AI competition between Chinese and American tech firms. It reflects the broader trend of rapid innovation and price adjustments in the AI sector, driven by:

  1. The success of startups like DeepSeek
  2. Pressure on established players to innovate and reduce costs
  3. Growing emphasis on efficiency in AI training and inference 35

Accessibility and Future Applications

While Hunyuan Turbo S is technically available via API on Tencent Cloud with a free one-week trial, it is not yet widely accessible for public download. Developers and businesses need to join a waiting list through Tencent Cloud to gain API access 5.

Tencent envisions Hunyuan Turbo S as a core foundation model for future applications, particularly in:

  1. Inference
  2. Text generation
  3. Code generation 3

The model's focus on speed makes it potentially ideal for real-time applications such as virtual assistants and customer service bots, areas of particular interest in the Chinese market 5.

Broader Context: AI Competition in China

The introduction of Hunyuan Turbo S is part of a larger trend of intensifying AI competition in China. Other recent developments include:

  1. Alibaba's introduction of the Qwen QwQ-Max reasoning model
  2. Alibaba's commitment to a $52 billion investment in AI infrastructure over three years
  3. DeepSeek's plans to release its next reasoning model, DeepSeek R2, earlier than initially scheduled 4

As the AI race continues to heat up, with both established tech giants and startups vying for dominance, the industry can expect further innovations in model performance, efficiency, and cost-effectiveness.
