DeepSeek R1T2 – An enhanced AI language model released by TNG, based on DeepSeek

What is DeepSeek R1T2?

DeepSeek R1T2 (also known as DeepSeek-TNG R1T2 Chimera) is an advanced AI language model developed by TNG based on the original DeepSeek model. It adopts a Tri-Mind architecture, combining the strengths of three parent models: DeepSeek R1-0528, R1, and V3-0324. Through Assembly of Experts (AoE) technology, it integrates strong reasoning abilities, structured thinking, and concise instruction-following behavior.

R1T2 offers a significant speed boost—200% faster than R1-0528 and 20% faster than R1, while reducing output length by 60%, which drastically lowers computational costs. It performs well in intelligence benchmarks, reaching up to 92% of R1-0528’s performance, and resolves the limitations seen in the first-generation R1T. Designed for enterprise-level use, R1T2 is ideal for applications requiring robust reasoning with tight efficiency and cost constraints—making it a full-fledged successor to R1.

Key Features of DeepSeek R1T2

• High-Speed Inference & Efficiency Gains
  R1T2 significantly improves reasoning speed—200% faster than R1-0528 and 20% faster than R1. By reducing output token length to roughly 40% of R1-0528, it minimizes both inference time and compute load.

• Balanced Intelligence & Efficiency
  R1T2’s Tri-Mind architecture fuses the reasoning prowess of R1-0528, the structured cognition of R1, and the concise, instruction-following behavior of V3-0324. It outperforms R1 in benchmarks like GPQA and AIME-2024, reaching 90%–92% of R1-0528’s intelligence.

• Concise Output & Cost Optimization
  Output from R1T2 is about 20% more concise than R1, making it particularly well-suited for high-throughput and cost-sensitive deployments.

• Stable Dialogue and Response Consistency
  Even without explicit system prompts, R1T2 maintains natural and consistent dialogue interactions—solving behavioral issues found in earlier R1T models.

• Open Source & Customizable
  R1T2 is available on Hugging Face under the MIT license, allowing developers to fine-tune, reinforce, or privately deploy the model as needed.

Technical Architecture of DeepSeek R1T2

• Tri-Mind Architecture
  Combines the strengths of three parent models:

  • R1-0528: Advanced reasoning

  • R1: Structured logical thinking

  • V3-0324: Concise instruction-following behavior

• Assembly of Experts (AoE)
  Unlike runtime MoE (Mixture of Experts), AoE fuses weight tensors from multiple pretrained models at the architectural level. This lets R1T2 inherit the reasoning strength of its parents while reducing redundant outputs.

• Inference Optimization
  R1T2 generates about 40% the token count of R1-0528, leading to 60% shorter outputs, which directly translates to lower inference time and computational cost. It also achieves ~20% improvement in output conciseness compared to R1.

• Preserved Intelligence Levels
  Despite shorter outputs, R1T2 performs exceptionally well in GPQA Diamond and AIME-2024/2025 benchmarks, maintaining 90%–92% of R1-0528’s intelligence level.

• Expert Tensor Fusion
  Integrates expert tensors from R1 and foundational structures from V3-0324, selectively adopting R1-0528’s advancements. This achieves an optimal trade-off between reasoning quality and efficiency.

• No Retraining Required
  R1T2 is built without additional fine-tuning or retraining—capabilities are inherited through direct weight tensor interpolation and merging, saving both time and resources.

• Consistent Behavioral Traits
  R1T2 retains R1’s behavioral features, including step-by-step chain-of-thought reasoning when needed—crucial for complex reasoning scenarios.
