# LongBench: A Multilingual, Multitask Benchmark Tailored for Long Context Understanding
**LongBench** is the first comprehensive dataset for multi-language, multi-task, and comprehensive assessment of **long text understanding** capabilities of large language models. In the context of the widespread attention to the multi-language capabilities of large models, LongBench includes different languages (Chinese and English) to provide a more comprehensive evaluation of the large models' multi-language capabilities in long texts. In addition, LongBench consists of twenty different tasks, covering key long-text application scenarios such as single-document QA, multi-document QA, summaries, few-shot learning, code completion, and synthesis tasks.
**LongBench** is the first comprehensive dataset for multilingual, multitask, and comprehensive assessment of **long context understanding** capabilities of large language models. LongBench includes different languages (Chinese and English) to provide a more comprehensive evaluation of the large models' multilingual capabilities on long contexts. In addition, LongBench consists of 20 different tasks, covering key long context application scenarios such as single-document QA, multi-document QA, summarization, few-shot learning, code completion, and synthetic tasks.
We are fully aware of the potentially high costs involved in the model evaluation process, especially in the context of long-text scenarios (such as manual annotation costs or API call costs). Therefore, we have adopted a fully automated evaluation method, aimed at measuring and evaluating the model's ability to understand long texts at the lowest cost and most effectively.

Therefore, we adopt a fully automated evaluation method, aimed at measuring and evaluating the model's ability to understand long contexts at the lowest cost.
LongBench includes 13 English tasks, 5 Chinese tasks, and 2 code tasks, with the average length of most tasks ranging from 5k to 15k. From the main task categories, LongBench includes six types of tasks, namely multi-document QA, single-document QA, summaries, Few-shot learning, synthetic tasks, and code completion. For detailed statistics and construction methods of LongBench tasks, please refer [here](task.md).

Here is the average score (%) of all models on various major tasks in both Chinese and English languages under the Zero-shot scenario. Please refer to this [link](task.md) for the evaluation metrics used for each task.

#### Variation of Abilities under Different Text Lengths
To more specifically analyze the model's relative performance under different text lengths, the following chart shows the average relative scores on all tasks over different text length intervals.
#### Variation of Abilities under Different Context Lengths
To more specifically analyze the models' relative performance under different context lengths, the following chart shows the average relative scores on all tasks over different context length intervals.

> Note: Assume that the model scores x on the data within a specific length range of a task, and y on all data of that task, then the model's **relative score** for that length range is (x/y-1). To better compare the trends of different models, we shift all the lines to 0 from 0-4k.

You can modify them during the evaluation to better suit the model you want to evaluate. After modification, when evaluating with [pred.py](pred.py), the data will be automatically organized according to the new format to get the corresponding model output.
