The Qwen3.5-397B-A17B-NVFP4: A Breakthrough in Large Language Model Efficiency
This latest model marks an unprecedented achievement in large language model efficiency, integrating a 397-billion parameter architecture with the ultra-low-precision NVFP4 data type. By leveraging NVFP4 quantization, the model achieves a substantial reduction in memory footprint while preserving near-full-precision performance, making it ideal for deployment on consumer-grade GPUs.
Key Performance Metrics
â˘
- Sub-50ms inference latency
- Throughput of over 200 tokens per second
- Better than previous 400B-scale models in terms of performance and efficiency
Mixture-of-Experts Routing Scheme
The Qwen3.5-397B-A17B-NVFP4’s training pipeline incorporates a novel mixture-of-experts routing scheme that balances load across the A17B accelerator cluster, resulting in stable convergence and robust multilingual capabilities.
| Model | Parameters | Precision | Latency (ms) | Throughput (tokens/s) |
