InfiniteBench: Extending Long Context Evaluation Beyond 100K Tokens

中文 • English • Paper

Introduction

Welcome to InfiniteBench, a cutting-edge benchmark tailored for evaluating the capabilities of language models to process, understand, and reason over super long contexts (100k+ tokens). Long contexts are crucial for enhancing applications with LLMs and achieving high-level interaction. InfiniteBench is designed to push the boundaries of language models by testing them against a context length of 100k+, which is 10 times longer than traditional datasets.

Features

• Loooong Context: InfiniteBench is a pioneer in testing language models with a context length of 100k+, offering an unparalleled challenge in the field.
• Diverse Domain: The benchmark comprises 12 unique tasks, each crafted to assess different aspects of language processing and comprehension in extended contexts.
• Specialized Test: InfiniteBench consists of tasks that state-of-the-art LLMs are known to be capable of when using shorter context. This ensures that the performance degradation is only caused by the length of the contexts.
• Real-World and Synthetic Scenarios: The tasks are a mix of real-world scenarios and synthetic constructs, ensuring a comprehensive evaluation of models. Real-world scenarios make the test pragmatic, and synthetic ones leave the space for extending the context length further with ease.

How to Download Data

Click here to download data from 🤗 Huggingface directly: https://huggingface.co/datasets/xinrongzhang2022/InfiniteBench

Using 🤗 Datasets

Alternatively, you can download using the 🤗 Datasets library as follows.

from datasets import load_dataset
dataset = load_dataset("xinrongzhang2022/InfiniteBench")

Using Scripts

cd InfiniteBench
bash scripts/download_dataset.sh

This will directly dump the data to data.

Evaluation Result

We evaluate SOTA proprietary and open-source LLMs, the result is as follows.

Note:

1. The evaluation code for YaRN-Mistral-7B is implemented by ourselves, and please contact us or submit an issue if there are any problems.

2. Kimi-Chat, Claude 2, and GPT-4 are evaluated using the official API with default configuration.

3. For Math.Calc, the values in the parentheses have a measurement unit of 0.01%. This is because it is easy to get a very low score on this task.

4. The metric for task Math.Find, Math.Calc, Code.Run, Code.Debug, En.Dia, En.MC, Retrieve.KV, Retrieve.Number, and Retrieve.PassKey is accuracy;

   The metric for task Zh.QA and En.QA are ROUGE F1 score;

   The metric for En.Sum is the rougeLsum score from the 🤗 Evaluate library.

Installation

pip install -r requirements.txt

How to Run

Download the dataset the data folder (or set the --data_dir argument to the location of the dataset). The data folder structure should be as follows.

InfiniteBench
├── data
│   ├── code_debug.jsonl
│   ├── code_run.jsonl
│   ├── kv_retrieval.jsonl
│   ├── longbook_choice_eng.jsonl
│   ├── longbook_qa_chn.jsonl
│   ├── longbook_qa_eng.jsonl
│   ├── longbook_sum_eng.jsonl
│   ├── longdialogue_qa_eng.jsonl
│   ├── math_calc.jsonl
│   ├── math_find.jsonl
│   ├── number_string.jsonl
│   ├── passkey.jsonl
│   └── construct_synthetic_dataset.py
...

Then, in the src folder, execute:

python eval_yarn_mistral.py --task kv_retrieval
python eval_gpt4.py --task longbook_sum_qa
python eval_rwkv.py --task passkey

The available tasks are:
