SpecQuant框架通过多父量化实现LLM自适应高效推理

SpecQuant是一种无需重新训练的框架，结合了推测解码和多父量化技术。它从共享基础模型中导出多个量化变体（INT4、FP8、FP16），并基于预测的复杂度动态路由查询。对于简单或事实性任务使用轻量级变体，对于复杂推理或长上下文输入则使用全精度模型。在Qwen2.5模型上，SpecQuant在MMLU、AlpacaEval和GSM8K基准测试中实现了35-43%的速度提升，且准确率下降不超过2%。

Conflict check

Dedup data only shows that these sources discuss the same event, not that they agree. There is no structured supporting or refuting evidence yet, so no conflict is inferred automatically.
