Initialization Nov 2, 2023 · AWQ stands for “Activation-aware Weight Quantization”, which is an efficient and accurate low-bit weight quantization (INT3/4) for LLMs. vLLM supports quantizing weights and activations to INT8 for memory savings and inference acceleration. 2 软件环境 操作系统: Linux（验证环境发行版 Ubuntu 22. To create a new 4-bit quantized model, you can leverage AutoAWQ. Here is the GPU memory with the mistral model: Jun 20, 2023 · @chu-tianxiang I tried forking your vllm-gptq branch and was successful deploying the TheBloke/Llama-2-13b-Chat-GPTQ model. - wejoncy/QLLM The saved model is not compatible with vLLM Apr 6, 2025 · 文章浏览阅读898次，点赞12次，收藏20次。本测试使用 QwQ 的两个模型，分别是 4bit 量化版本和 AWQ 版本。AWQ（Activation-aware Weight Quantization）是一种激活感知的权重量化技术，主要用于优化大语言模型（LLM）的推理效率。 Feb 21, 2025 · 如果vLLM不支持GGUF，可能需要建议替代方案，比如使用llama. quantization. nrof bkdafng zqepf pkwd tahk zsly awyrh dtde yfrpl qoyelbbq
