#47 — Hunyuan-T1
March 22, 2025•3 min read
Tencent's Hunyuan team just launched a game-changing AI model that's got the tech world buzzing. Here's what startup founders need to know about Hunyuan-T1:
The Big Picture
- First-ever ultra-large model powered by Mamba architecture
- Built on TurboS, a hybrid Transformer-Mamba MoE base
- Crushes benchmarks, rivaling top models like DeepSeek R1
Why It Matters
- Speed Demon: Decodes 2x faster than competitors
- Long-Text Mastery: Solves context loss issues plaguing other models
- Efficiency Boost: Mamba optimizes long sequences while cutting compute costs
The Secret Sauce
- 96.7% of training focused on reinforcement learning
- Curriculum learning approach gradually ramped up difficulty
- Self-rewarding system for human preference alignment
Technical Innovations
The Hunyuan-T1 introduces groundbreaking architectural innovations that fundamentally change the AI reasoning landscape:
Hybrid-Mamba-Transformer Architecture
Tencent is the first in the industry to successfully implement a hybrid architecture combining Google's Transformer with the Mamba architecture (developed by Carnegie Mellon and Princeton). This fusion:
- Effectively reduces computational complexity of traditional Transformer structures
- Decreases KV-Cache memory occupancy significantly
- Leverages Mamba's strengths in handling long sequences while retaining Transformer's ability to capture complex contexts
The hybrid approach delivers a 44% reduction in first-word latency and doubles word output speed compared to traditional models. This allows Hunyuan-T1 to generate responses at 60-80 tokens per second, making it feel almost instantaneous to users.
MoE Implementation
Tencent has successfully applied the Mamba architecture to ultra-large Mixture of Experts (MoE) models without performance loss—an industry first. This implementation:
- Enables more efficient parameter utilization
- Allows the model to maintain high performance while reducing computational demands
- Supports the processing of ultra-long texts with maintained coherence and organization
Benchmark Beatdown
- MMLU-PRO: 87.2 (2nd only to OpenAI's o1 at 89.3, beating GPT-4.5's 86.1)
- Logical reasoning: 93.1 (surpassing OpenAI's o1, GPT-4.5, and DeepSeek R1)
- CEval (Chinese language): 91.8 (matching R1 and beating o1's 87.8)
- AIME 2024: 78.2 (slightly behind R1's 79.8 and o1's 79.2)
Bottom Line for Founders
Tencent's Hunyuan-T1 isn't just another AI model – it's a glimpse into the future of machine reasoning. With its Mamba-powered architecture and laser focus on reinforcement learning, this beast could redefine what's possible in AI-powered applications. At competitive pricing (1 yuan/$0.14 per million tokens input, 4 yuan per million tokens output), it offers startup founders an accessible path to cutting-edge AI capabilities. Keep a close eye on how this tech evolves – it might just be the edge your startup needs to disrupt the market.

#48 — Cold Take: Broad automation trumps R&D acceleration
While institutions focus on AI for research breakthroughs, economic data suggests the real value lies in widespread automation.
#49 — Gemini 2.5 Pro
Google's new "thinking model" AI shows impressive reasoning capabilities with a 40-point lead on human preference benchmarks.
#50 — Leading in uncertain times
Economic uncertainty demands a different leadership approach. In times of crisis, how leaders respond defines not just their survival, but their company's future success. The most effective leaders combine push and pull styles, focus on the "4 C's" (Communication, Conviction, Confidence, Calmness), and build trust through competence, integrity, and benevolence.
