- # MiniMind Max2
24
 
25
- **Tiny Model, Powerful Experience** - A lightweight, efficient language model designed for edge deployment, inspired by MiniMax M2's efficient activated parameters design.
26
 
27
- ## Model Description
28
 
29
- MiniMind Max2 is a family of efficient language models that leverage Mixture of Experts (MoE) architecture to achieve high performance with minimal active parameters. Only 25% of parameters are activated per token, enabling deployment on resource-constrained devices like smartphones, tablets, and IoT devices.
 
 
 
30
 
31
- ## Key Features
32
 
33
- - **Efficient MoE Architecture**: Only 25% of parameters activated per token
34
- - **Grouped Query Attention (GQA)**: 4:1 ratio for memory efficiency
35
- - **Multiple Model Sizes**: From 500M (Nano) to 3B (Pro) parameters
36
- - **Edge-Ready**: Runs on Android, iOS, and embedded devices
37
- - **Easy Deployment**: Export to ONNX, GGUF (llama.cpp), TFLite
38
 
39
- ## Model Variants
40
 
41
- | Model | Total Params | Active Params | Size (INT4) | Target Device |
42
- |-------|-------------|---------------|-------------|---------------|
43
- | **max2-nano** | 500M | 125M | ~300MB | Smartwatch, IoT |
44
- | **max2-lite** | 1.5B | 375M | ~900MB | Mobile phones |
45
- | **max2-pro** | 3B | 750M | ~1.8GB | Tablets, laptops |

- ## Architecture Details
 
 
 
 
 
 
 
 
 
129
 
130
- ### Mixture of Experts (MoE)
131
- - 8 experts with top-2 routing (25% activation)
132
- - Load balancing auxiliary loss for expert utilization
133
- - Efficient sparse computation
134
 
135
- ### Grouped Query Attention (GQA)
136
- - 4:1 ratio (4 query heads per KV head)
137
- - Reduced memory footprint for KV cache
138
- - Maintains quality with fewer parameters
139
 
140
- ### Core Optimizations
141
- - **RMSNorm**: Faster than standard LayerNorm
142
- - **SwiGLU**: Improved activation function
143
- - **RoPE**: Rotary Position Embeddings for long context
144
- - **Flash Attention**: Compatible for memory-efficient attention

+ ### MiniMind Max2: Efficient Language Models for Edge Deployment
 
 
 
 
 
583
 
584
+ **Abstract**: We present MiniMind Max2, a family of efficient language models designed for deployment on resource-constrained devices. By combining Mixture of Experts (MoE) with Grouped Query Attention (GQA), our models achieve competitive performance while activating only 25% of parameters per token. The max2-nano variant (500M total, 125M active) runs at 45+ tokens/second on mobile devices, while max2-pro (3B total, 750M active) achieves state-of-the-art efficiency on edge hardware.
585
 
586
+ **Key Contributions**:
587
+ 1. Efficient MoE architecture with 8 experts and top-2 routing
588
+ 2. GQA with 4:1 query-to-KV ratio for memory efficiency
589
+ 3. Comprehensive deployment toolkit for mobile and edge devices
590
+ 4. Extensive benchmarks across multiple hardware platforms
