Architectural Innovation: Dual-Version Design for Diverse Scenarios

The new model introduces a dual-version architecture tailored for different use cases:

Pro Version

• 1.6T total parameters with 49B activated per token
• Achieves 98.7% accuracy in complex reasoning through dynamic sparse activation
• Optimized for high-precision tasks requiring full parameter utilization

Flash Version

• 284B total parameters with 13B activated per token
• Reduces GPU memory usage to 1/5 of industry average via parameter sharing
• Delivers 4.2× faster inference than predecessors while maintaining 89.3% accuracy in code generation

Both versions implement hierarchical attention mechanisms:

# Hierarchical Attention Implementation
class HierarchicalAttention(nn.Module):
    def __init__(self, local_window=512, global_ratio=0.1):
        self.local_attn = LocalAttention(window_size=local_window)
        self.global_attn = GlobalAttention(sample_ratio=global_ratio)
    def forward(self, x):
        local_out = self.local_attn(x)  # Local context processing
        global_out = self.global_attn(x) # Global dependency capture
        return F.normalize(local_out + global_out, dim=-1)

This design achieves 97.4% accuracy in attention weight allocation for million-token sequences.

Long-Context Processing Revolution

The model natively supports 1 million-token context windows, enabling:

• 175万-word Chinese text processing (~2.5× Dream of the Red Chamber)
• 100,000-line codebase analysis with comments
• 500-page contract parsing alongside relevant regulations

Key Technical Breakthroughs

1. Dynamic Position Encoding

   • Extended RoPE decay period to 10⁶ scale
   • Maintains 92.3% position information retention in long sequences

2. KV Cache Compression

   • Reduces memory usage to 7-10% of previous versions
   • Example: 480GB → 35GB on A100 GPU for million-token processing

3. Segmented Inference Mechanism

   • Adaptive loading algorithm reduces peak memory by 83%

     # Segmented Inference Implementation
     def segmented_inference(model, input_tokens, segment_size=32768):
     outputs = []
     for i in range(0, len(input_tokens), segment_size):
        segment = input_tokens[i:i+segment_size]
        history = segment[-1024:] if i > 0 else []  # Maintain context
        output = model.generate(segment, context=history)
        outputs.append(output)
     return concatenate(outputs)

Efficiency Breakthroughs

Performance improvements in million-token scenarios:
| Metric | Pro vs Previous | Flash vs Previous |
|———————————-|————————|—————————|
| FLOPs per token | 27% reduction | 10% reduction |
| KV cache usage | 10% of original| 7% of original |
| End-to-end latency | 31% reduction | 14% reduction |
