+Introduction
+
+Qwen1.5 is the beta version of Qwen2, a transformer-based decoder-only language model pretrained on a large amount of data. In comparison with the previous released Qwen, the improvements include:
+
+    8 model sizes, including 0.5B, 1.8B, 4B, 7B, 14B, 32B and 72B dense models, and an MoE model of 14B with 2.7B activated;
+    Significant performance improvement in Chat models;
+    Multilingual support of both base and chat models;
+    Stable support of 32K context length for models of all sizes
+    No need of trust_remote_code.
+
+For more details, please refer to our blog post and GitHub repo.
+Model Details
+
+Qwen1.5 is a language model series including decoder language models of different model sizes. For each size, we release the base language model and the aligned chat model. It is based on the Transformer architecture with SwiGLU activation, attention QKV bias, group query attention, mixture of sliding window attention and full attention, etc. Additionally, we have an improved tokenizer adaptive to multiple natural languages and codes. For the beta version, temporarily we did not include GQA (except for 32B) and the mixture of SWA and full attention.
+Requirements
+
+The code of Qwen1.5 has been in the latest Hugging face transformers and we advise you to install transformers>=4.37.0, or you might encounter the following error:

+)
+
+# load un-quantized model, by default, the model will always be loaded into CPU memory
+model = AutoGPTQForCausalLM.from_pretrained(pretrained_model_dir, quantize_config)
+
+# quantize model, the examples should be list of dict whose keys can only be "input_ids" and "attention_mask"

+
+# push quantized model to Hugging Face Hub.
