Qwen3.8-27B让本地推理提速

💡单张3090即可本地运行27B模型,并以约2.28倍加速挑战高价API。
⚡ 30-Second TL;DR
What Changed
Qwen3.8-27B在Artificial Analysis获得52分,性能追平284B参数的DeepSeek V4 Flash。
Why It Matters
Efficient open-weight models could reduce dependence on expensive hosted APIs for coding, RAG and agent workflows. The practical advantage is strongest for single-user inference on 24GB GPUs; limited concurrency and uncertain performance on untested tasks remain important constraints.
What To Do Next
Download the Qwen3.8-27B W4A16 weights and benchmark them with vLLM, MTP enabled and disabled, on your target 24GB GPU using your own coding or RAG prompts.
Key Points
- •Qwen3.8-27B在Artificial Analysis获得52分,性能追平284B参数的DeepSeek V4 Flash。
- •W4A16量化结合int8/int4二次量化,可将模型与KV cache控制在单张24GB显卡内,并支持64K上下文。
- •投机解码将基线速度从46 tok/s提升至最高381 tok/s,但普通聊天提示词下约为133 tok/s。
- •3090独立测试从52.7 tok/s提升至120 tok/s,HumanEval达到92.7%,但尚未完成与BF16模型的完整同协议对比。
