Yuan2.0-M32: Mixture of Experts with Attention Router
🌎 GitHub • 🤗 Hugging Face • 💬 WeChat• 📎 Yuan2.0-M32 Paper
1. Introduction
Yuan2.0-M32 is a Mixture-of-Experts (MoE) language model with 32 experts, of which 2 are active. A new router network, Attention Router, is proposed and has been adopted for more efficient expert selection, boosting accuracy by 3.8% over models using a classical router network. Yuan 2.0-M32 is trained from scratch with 2000B tokens, and its training computation is only 9.25% of that required by a dense model of the same parameter scale. Demonstrating competitive capabilities in coding, math, and various specialized fields, Yuan2.0-M32 operates with only 3.7B active parameters out of a total 40B, and a forward computation of 7.4 GFLOPS per token, which is just 1/19th of Llama3-70B's requirement. Yuan 2.0-M32 has surpassed Llama3-70B on the MATH and ARC-Challenge benchmarks, achieving accuracies of 55.9% and 95.8%, respectively. The basic information of the Yuan2.0-M32 model is as follows:
- Total Parameters ： 40B
- Experts： 32
- Active Experts： 2
- Active Parameters： 3.7B
- Training Tokens： 2000B tokens
- Sequence Length： 16K
The technical report for the Yuan2.0-M32 model has been released, and you can find more detailed technical information and evaluation results by referring to the paper.

3. Evaluation
3.1 Benchmarks 🏆
We conducted a thorough evaluation of the Yuan2.0-M32 model across a range of benchmarks, including HumanEval, GSM8K, MMLU, Math, and ARC-Challenge. These benchmarks are designed to test the model's proficiency in key areas such as natural language understanding, knowledge acquisition, mathematical computation and reasoning, and code generation. The Yuan2.0-M32 has shown a consistent and significant advantage over other models like Llama3-8B and Mistral-8×7B, excelling in all evaluated tasks. Remarkably, its overall performance is on par with the more substantial Llama3-70B model.The detailed evaluation results are outlined in the subsequent table.
| Model | HumanEval | GSM8K | MMLU | Math | ARC-C* |
|---|---|---|---|---|---|
| Llama3-70B | 81.7% | 93% | 80.3 | 50.4% | 93.3% |
| Llama3-8B | 62.2% | 79.6% | 68.4% | 30% | 78.6% |
| Phi-3-medium | 62.2% | 91.0% | 78.0% | - | 91.6% |
| Phi-3-small | 61% | 89.6% | 75.7% | - | 90.7% |
| Phi-3-mini | 58.5% | 82.5% | 68.8% | - | 84.9% |
| Mistral-8*22B | 45.1% | 78.6% | 77.8% | 41,8% | 91.3% |
| Mistral-8*7B | 40.2% | 58.4% | 70.86% | 28.4% | 85.9% |
| Yuan2.0-M32 | 74.4% | 92.7% | 72.2% | 55.9% | 95.8% |
* ARC-C: AI2 Reasoning Challenge (ARC) benchmark contains more complex parts that need further reasoning.
