We opensource our **Aquila2** series, now including **Aquila2**, the base language models, namely **Aquila2-7B** and **Aquila2-34B**, as well as **AquilaChat2**, the chat models, namely **AquilaChat2-7B** and **AquilaChat2-34B**, as well as the long-text chat models, namely **AquilaChat2-7B-16k** and **AquilaChat2-34B-16k** The additional details of the Aquila model will be presented in the official technical report. Please stay tuned for updates on official channels. ## Base Model Performance


## Quick Start Aquila-7B ### 1. Inference ```python from transformers import AutoTokenizer, AutoModelForCausalLM import torch device = torch.device("cuda") model_info = "BAAI/Aquila2-7B" tokenizer = AutoTokenizer.from_pretrained(model_info, trust_remote_code=True) model = AutoModelForCausalLM.from_pretrained(model_info, trust_remote_code=True) model.eval() model.to(device) text = "请给出10个要到北京旅游的理由。" tokens = tokenizer.encode_plus(text)['input_ids'][:-1] tokens = torch.tensor(tokens)[None,].to(device) stop_tokens = ["###", "[UNK]", ""] with torch.no_grad(): out = model.generate(tokens, do_sample=True, max_length=512, eos_token_id=100007, bad_words_ids=[[tokenizer.encode(token)[0] for token in stop_tokens]])[0] out = tokenizer.decode(out.cpu().numpy().tolist()) print(out) ``` ## License Aquila2-7B and AquilaChat2-7B open-source model is licensed under [ BAAI Aquila Model Licence Agreement](https://huggingface.co/BAAI/Aquila2-7B/blob/main/BAAI-Aquila-Model-License%20-Agreement.pdf)
