vLLM标志在A100 GPU测试中将代币成本降低了68%

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-01 03:01

一位开发者使用A100 GPU和Qwen2.5-0.5B模型测试了一个vLLM标志`max_num_seqs`对代币成本的影响。通过交错测试运行以应对机器漂移，他们发现将`max_num_seqs`从1增加到8，成本显著降低了约68%。开发者指出，1的基线不切实际地低，并且结果可能因更大的模型和不同的流量模式而异。他们还发布了一个开源工具`throttle-pro`，以帮助其他人自信地测量代币成本。 AI

影响优化vLLM配置可以显著降低部署LLM的成本，使其更易于访问。

我租用了一台A100来测试一个vLLM标志

I rented an A100 for under an hour to answer one question. Does a single vLLM flag really change what a token costs? The flag was <code>max_num_seqs</code>: how many requests the server works on at once. I set it to 1, which is a deliberately bad setting, and the…
