}'Index-1.9B-32K is a language model with only 1.9 billion parameters, yet it supports a context length of 32K (meaning this extremely small model can read documents of over 35,000 words in one go). The model has undergone Continue Pre-Training and Supervised Fine-Tuning (SFT) specifically for texts longer than 32K tokens, based on carefully curated long-text training data and self-built long-text instruction sets. The model is now open-source on both Hugging Face and ModelScope.
Despite its small size (about 2% of models like GPT-4), Index-1.9B-32K demonstrates excellent long-text processing capabilities. As shown in the figure below, our 1.9B-sized model's score even surpasses that of the 7B-sized model. Below is a comparison with models like GPT-4 and Qwen2:
Comparison of Index-1.9B-32K with GPT-4, Qwen2, and other models in Long Context capability
In a 32K-length needle-in-a-haystack test, Index-1.9B-32K achieved excellent results, as shown in the figure below. The only exception was a small yellow spot (91.08 points) in the region of (32K length, 10% depth), with all other areas performing excellently in mostly green zones.

Depends on bitsandbytes, installation command:
pip install bitsandbytes==0.43.0You can use the following script to perform int4 quantization, which has less performance loss and further saves video memory usage.
import torch
import argparse
from transformers import (
AutoModelForCausalLM,
AutoTokenizer,
TextIteratorStreamer,
GenerationConfig,
BitsAndBytesConfig
)
parser = argparse.ArgumentParser()
parser.add_argument('--model_path', default="", type=str, help="")
parser.add_argument('--save_model_path', default="", type=str, help="")
args = parser.parse_args()
tokenizer = AutoTokenizer.from_pretrained(args.model_path, trust_remote_code=True)
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,

Index-1.9B may generate inaccurate, biased, or otherwise objectionable content in certain situations. The model cannot understand, express personal opinions, or make value judgments. Its outputs do not represent the views and positions of the model developers. Therefore, please use the generated content with caution. Users should independently evaluate and verify the content generated by the model and should not disseminate harmful content. Developers should conduct safety tests and fine-tuning according to specific applications before deploying any related applications.
We strongly advise against using these models to create or disseminate harmful information or engage in activities that may harm public, national, or social security or violate regulations. Do not use the models for internet services without proper safety review and filing. We have made every effort to ensure the compliance of the training data, but due to the complexity of the model and data, unforeseen issues may still exist. We will not be held responsible for any problems arising from the use of these models, whether related to data security, public opinion risks, or any risks and issues caused by misunderstanding, misuse, dissemination, or non-compliant use of the model.
Using the source code from this repository requires compliance with the Apache-2.0. The use of the Index-1.9B model weights requires compliance with the INDEX_MODEL_LICENSE.
The Index-1.9B model weights are fully open for academic research and support free commercial use.
