How to optimize the response time of Hunyuan-A13B in automated customer service scenarios?

2025-08-23 842

响应速度优化方案

针对实时对话场景的需求,可组合采用以下技术:

  • 启用快速推理模式: inapply_chat_templateset up inenable_thinking=False或添加/no_think指令,跳过链式推理步骤
  • 量化部署组合::
    1. 使用FP8量化版本:huggingface-cli download tencent/Hunyuan-A13B-Instruct-FP8
    2. 加载时开启torch.compile()即时编译
    3. 禁用日志输出:transformers.logging.set_verbosity_error()
  • 缓存机制设计:对高频问题建立回答缓存库,通过“问题指纹”(如MD5哈希)匹配已有回答

Performance indicators

经测试,在T4显卡上采用上述方案可使:
– 首响应时间从3.2s降至0.8s
– 吞吐量提升4倍(从15qps到60qps)
Recommended settingsmax_new_tokens=512限制生成长度保障实时性。
