Practical application value of quantitative techniques
The Hunyuan-A13B offers both FP8 and GPTQ-Int4 professional quantization solutions:
- FP8 version: Suitable for medium configuration GPUs (e.g. RTX 3090) with a reduced memory footprint of 40%
- GPTQ-Int4 version: Runs on graphics cards with 10GB of VRAM for a 2.3x speed increase
Quantization techniques combined with the MoE architecture make it possible for models to be deployed at edge devices. Measured data shows:
- Int4 version inference up to 85 tokens/s (A100 graphics card)
- The FP8 version loses only 1.21 TP3T of accuracy on the mathematical reasoning task
For different deployment environments, Tencent provides TensorRT-LLM back-end optimization solutions. Developers can also customize quantization based on open source code, and the technical manual explains in detail the trade-offs between different quantization strategies (accuracy vs. speed vs. memory), which is especially important for industrial-grade applications.
