2023.10.12 🔥 We release Aquila2 series on BAAI ModelHub and Hugging Face.
Aquila2 series outperforms the models of similar model sizes on a series of benchmark datasets.
Note： We have discovered a data leakage problem with the GSM8K test data in the pre-training task dataset. Therefore, the evaluation results of GSM8K have been removed from the evaluation results.
Upon thorough investigation and analysis, it was found that the data leakage occurred in the mathematical dataset A (over 2 million samples), recommended by a team we have collaborated with multiple times. This dataset includes the untreated GSM8K test set (1319 samples). The team only performed routine de-duplication and quality checks but did not conduct an extra filtering check for the presence of the GSM8K test data, resulting in this oversight.
Our team has always strictly adhered to the principle that training data should not include test data. Taking this lesson from the error caused by not thoroughly checking the source of external data, we have investigated all 2 trillion tokens of data for various test datasets, including WTM22（en-zh), CLUEWSC, Winograd, HellaSwag, OpenBookQA, PIQA, ARC-e, BUSTSM, BoolQ, TruthfulQA, RAFT, ChID, EPRSTMT, TNEWS, OCNLI, SEM-Chinese, MMLU, C-Eval, CMMLU, CSL and HumanEval.
In evaluating generative chat models, our team prioritizes how models autonomously respond to questions—a reflection of real-world user interactions. Guided by Stanford University's HELM [1] approach, our assessment emphasizes context understanding and instruction adherence. In some cases, models may deliver answers not in line with the instruction of input, resulting in a "0" score. For instance, if the model should respond with "A" but outputs "B" or "The answer is A", it earns a "0."
Other industry methods include concatenating "question+answer" and assessing the combined text's probability. However, in this method, the chat model doesn't generate content but computing probability scores. Due to its divergence from real-world chat scenarios, we haven't adopted this approach in our evaluations.

- python 3.10 and above
- pytorch 1.12 and above, 2.0 and above are recommended
- transformers 4.32 and above
- CUDA 11.4 and above are recommended (this is for GPU users, flash-attention users, etc.)
We have provided a straightforward example to illustrate how to quickly get started with Aquila2.
Before proceeding, ensure that your environment is properly configured and that the necessary packages have been installed. First and foremost, ensure that these prerequisites are met and then follow the instructions below to install the necessary libraries and dependencies.
pip install -r requirements.txt
If your device supports fp16 or bf16 precision, we also recommend installing flash-attention to enhance execution speed and reduce memory consumption. It's important to note that flash-attention is optional, and the project can be executed normally without it.
For the installation of flash-attention, please follow the instructions in https://github.com/Dao-AILab/flash-attention/.
For the environment that meets these requirements, you can also set up the environment required for Aquila2 by directly downloading the Docker TAR file, then loading and running it. Because of all already installed dependencies, in the container you just pull all sources FlagAI and Aquila2 and include both paths int environment variable, like export PYTHONPATH=$FLAGAI_HOME:$AQUILA2_HOME:$PYTHONPATH.
Now you can use BAAI Modelhub or 🤗 Transformers to run our model。
You can now use the AquilaChat2-7B model for inference as follows:
from flagai.auto_model.auto_loader import AutoLoader
# Model name
model_name = 'AquilaChat2-7B'
# model_name = 'AquilaChat2-34B'
# Load the model and tokenizer
autoloader = AutoLoader("aquila2", model_name=model_name)
# To modify the model loading path, use the model_dir parameter
# autoloader = AutoLoader("aquila2", model_dir='./checkpoints', model_name=model_name)
# To load the LoRA module, you need to provide the path to the LoRA module
# autoloader = AutoLoader("aquila2", model_name=model_name，lora_dir='./examples/checkpoints/lora/aquila2chat')
# To load the LoRA module, you need to provide the path to the LoRA module
# autoloader = AutoLoader("aquila2", model_name=model_name，qlora_dir='./examples/checkpoints/qlora/aquila2chat')
model = autoloader.get_model()
tokenizer = autoloader.get_tokenizer()
# Example
test_data = [
"Write a tongue twister that's extremely difficult to pronounce.",
]
for text in test_data:
print(model.predict(text, tokenizer=tokenizer, model_name=model_name, top_p=0.9, seed=123, topk=15, temperature=1.0))
# For Aquila2-7B or Aquila2-34B，you need to set sft=False
# print(model.predict(text, tokenizer=tokenizer, model_name=model_name, sft=False))The results of our execution are as follows:
Harry had a harpy flight, Fred had a fiddle, and George had a gecko for breakfast. Say that three times fast and see how long you can make it last!
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
device = torch.device("cuda:0")
model_info = "BAAI/AquilaChat2-7B"
tokenizer = AutoTokenizer.from_pretrained(model_info, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_info, trust_remote_code=True, torch_dtype=torch.bfloat16)
model.eval()
model.to(device)
text = "请给出10个要到北京旅游的理由。"
from predict import predict
out = predict(model, text, tokenizer=tokenizer, max_gen_len=200, top_p=0.95,
seed=1234, topk=100, temperature=0.9, sft=True, device=device,
model_name="AquilaChat2-7B")
print(out)You should use multiple gpus inference as follows:
from flagai.auto_model.auto_loader import AutoLoader
model_name = 'AquilaChat2-70B-Expr'
autoloader = AutoLoader("aquila2", model_name=model_name, all_devices=True)
model = autoloader.get_model()
tokenizer = autoloader.get_tokenizer()
test_data = [
"北京的十大景点是什么?",
"写一首中秋主题的五言绝句",
"Write a tongue twister that's extremely difficult to pronounce.",
]
for text in test_data:
print(model.predict(text, tokenizer=tokenizer, model_name=model_name, top_p=0.9, seed=123, topk=15, temperature=1.0))The example also can be found in AquilaChat2-70B-Expr .
Before using quantization, BitsAndBytes needs to be installed:
pip install bitsandbytes
After that, you're all set to use the quantized models for inference!
import torch
from flagai.auto_model.auto_loader import AutoLoader
from transformers import BitsAndBytesConfig
model_name = 'AquilaChat2-7B'
autoloader = AutoLoader("aquila2", model_name=model_name,
quantization_config=BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_use_double_quant=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.bfloat16,
))
model = autoloader.get_model()
tokenizer = autoloader.get_tokenizer()
#
test_data = [
"Write a tongue twister that's extremely difficult to pronounce.",
]
for text in test_data:
print(model.predict(text, tokenizer=tokenizer, model_name=model_name, top_p=0.9, seed=123, topk=15, temperature=1.0))AquilaChat2-34B 4Bit version has 99.3% of the performance of the bf16 version.
The 4Bit version of AquilaChat2-34B offers significantly better performance than the 7B model and has similar memory usage.

from awq import AutoAWQForCausalLM
from transformers import AutoTokenizer
awq_model_path = './checkpoints/aquilachat2-34b-awq'
model = AutoAWQForCausalLM.from_quantized(awq_model_path,trust_remote_code=True,fuse_layers=True)

from flagai.model.aquila2.utils import covert_prompt_to_input_ids_with_history
history = None
text = covert_prompt_to_input_ids_with_history(text, history, tokenizer, 2048, convo_template="aquila-legacy")
inputs = torch.tensor([text]).to(device)
outputs = model.generate(inputs)[0]
print(tokenizer.decode(outputs))From Aquila2, we upgrade the underlying pretraining framework, which is now open-sourced as FlagScale. It is based on the Megatron-LM project and aims at utilizing the computation resources efficiently for LLMs without sacrificing the numerical stability and model effectiveness.
In FlagScale, we firstly provide our actually used training schemes for Aquila2-7B and Aquila2-34B, including the parallel strategies, optimizations and hyper-parameter settings. By using FlagScale, our model FLOPs utilization can achieve a very high level for both Aquila2-7B and Aquila2-34B. For now, FlagScale is still in its early stage and we will work with the community together to support different LLMs on various hardware architectures in the future.
We provide users with a series of fine-tuning scripts designed to adapt models to various downstream tasks using custom data. Within the comments section of the scripts, users will find detailed instructions indicating which parameters may need adjustments based on specific needs.
Before initiating the fine-tuning process, you are required to have your training data prepared. All samples should be consolidated into a list and stored in a json file. Each sample should be represented as a dictionary, encompassing an ID and conversation, with the latter presented in list format. Below is an example for your reference:
{
"id": "alpaca_data.json_1",
"conversations": [{
"from": "human",
"value": "What are the three primary colors?"
}, {
"from": "gpt",
"value": "The three primary colors are red, blue, and yellow."
}],
"instruction": ""
}Subsequently, you can use the variety of fine-tuning scripts we offer for different purposes:
- Execute
finetune/7B/finetune.shfor a full parameter fine-tuning of the 7B model - Execute
finetune/7B/finetune_lora.shfor LoRA fine-tuning of the 7B model - Execute
finetune/7B/finetune_qlora.shfor Q-LoRA fine-tuning of the 7B model - Execute
finetune/34B/finetune.shfor a full parameter fine-tuning of the 34B model - Execute
finetune/34B/finetune_lora.shfor LoRA fine-tuning of the 34B model - Execute
finetune/34B/finetune_qlora.shfor Q-LoRA fine-tuning of the 34B model
Note that you are required to specify the path to the training data within the script, and configure the hostfile accordingly. If a custom model file is not provided in the script, it will automatically download the corresponding model from ModelHub based on the specified model name and proceed with the fine-tuning operation.
To perform full-parameter fine-tuning, execute the following scripts:
# Fine-tuning the 7B model
bash finetune/7B/finetune.sh
# Fine-tuning the 34B model
bash finetune/34B/finetune.shThe fine-tuning approach of LoRA (as detailed in the paper) varies from the full-parameter method. LoRA solely updates the parameters of the adapter layer without modifying the original language model parameters. This practice reduces memory and computational overhead. Applicable to a variety of model sizes and tasks, LoRA facilitates more efficient model fine-tuning to cater to specific tasks or datasets.
To implement LoRA, execute the following scripts:
# Fine-tuning the 7B model
bash finetune/7B/finetune_lora.sh
# Fine-tuning the 34B model
bash finetune/34B/finetune_lora.shIf memory resources remain constrained, consider employing Q-LoRA (refer to the paper), an optimized solution that further reduces memory usage through the utilization of 4-bit quantized models and paged attention techniques.
To implement Q-LoRA, execute the following scripts:
# Fine-tuning the 7B model
bash finetune/7B/finetune_qlora.sh
# Fine-tuning the 34B model
bash finetune/34B/finetune_qlora.shBelow are the data on memory usage and training speed for the 7B and 34B models using full-parameter fine-tuning, LoRA, and QLoRA with different input lengths. The evaluation was conducted on a machine equipped with an A100-SXM4-80G GPU, utilizing CUDA 12.1 and Pytorch 2.1. The input length for the 7B model is 2048, and for the 34B model, it is 4096. All tests were performed using a batch size of 4 and a gradient accumulation of 1, and both memory usage (in GB) and training speed (in s/iter) were recorded. The specific data is as follows:
| Model Size | Method | Memory | speed |
|---|---|---|---|
| 7B | SFT | 43.9G | 2.67s/iter |
| LoRA | 29.4G | 2.04s/iter | |
| Q-LoRA | 19.9G | 2.14s/iter | |
| 34B | Q-LoRA | 37.7G | 8.22s/iter |

This is a idea that uses langchain to implement a question-answer application based on local knowledge base. The goal is to build a knowledge base question-answer solution that is friendly to Chinese-English bilingual scenarios, can support open source models, and can run offline. This project relies on the open source LLM and Embedding models supported by BAAI, which can realize offline private deployment of all open source models. The project can be found in rag_pipe .
AquilaChat2-34B-16K is built on Aquila2-34B, processed by positional coding interpolation and SFT on 200k high-quality long text conversations dataset to extend the effective context window. We tested the model four Chinese and English long text quiz and summarization tasks from LongBench. The evaluation results show that AquilaChat2-34B-16K reaches the leading level of open source long text models, close to GPT-3.5-16k.
Our tokenizer of BBPE type is trained on a 50GB text dataset, mainly sampled from deduplicated Pile and WuDao corpus. We also add some special tokens for passage and conversation separation.
