Dual-Architecture Design: Balancing Performance and Cost

The new model employs a dual-version co-design strategy with differentiated parameter scales and activation mechanisms to address diverse deployment scenarios:

1. Pro Version (High-Performance)

• 1.6T total parameters with 49B active parameters per token
• Optimized architecture reduces single-token inference FLOPs to 27% of previous models
• 90% reduction in KV cache memory usage
• 10x memory efficiency for million-token processing scenarios
• Maintains 92% accuracy in code generation tasks with million-token contexts

2. Flash Version (Cost-Efficient)

• 284B total parameters with 13B active parameters per token
• Sparse activation mechanism reduces FLOPs to 10% of previous models
• 93% KV cache reduction while maintaining native million-token support
• 85% lower energy consumption compared to Pro version under equivalent conditions
• Ideal for edge computing and resource-constrained environments

Technical Breakthrough: Both versions utilize Mixture-of-Experts (MoE) architecture with dynamic routing, enabling parameter efficiency gains. Experimental data shows the Pro version maintains performance in long-context scenarios while the Flash version achieves significant energy savings.

Million-Token Context Processing: From Theory to Implementation

Context Capacity Revolution

The million-token capability enables processing equivalent to:

• 1.75 million Chinese characters (≈3,300 pages)
• Complete texts of Dream of the Red Chamber and Comprehensive Mirror for Aid in Government simultaneously
• 500,000-line code repositories in their entirety

Unlike traditional chunked processing with RAG retrieval that suffers from information loss, the native support enables true global understanding. In legal document analysis, the model identifies cross-chapter contractual conflicts in single passes.

Computational Optimization Strategies

1. Compressed Sparse Attention (CSA)

• Compression Phase: Aggregates m consecutive tokens (m=4 in experiments) into single entries using learnable weight matrices with residual connections
• Selection Phase: Dynamic sparse gating filters compressed KV pairs based on input relevance
• In code comprehension tasks, automatically focuses on function definitions and calls while ignoring comments and formatting

2. Hierarchical Caching System

• L1 Cache: Stores KV pairs for current processing block
• L2 Cache: Maintains compressed representations of adjacent blocks
• L3 Cache: Persists globally important information
• Achieves >90% cache hit rate in continuous text processing, reducing response latency by 65% in multi-turn dialogues

• 40% improvement in cross-document concept association
• 75% hardware cost reduction

3. Intelligent Programming Assistant

Integration with developer tools enables:

• Comprehensive project code understanding (500,000 lines)
• Cross-file function call tracing
• 10x expansion of code completion context window

Future Technology Evolution Trends
