# chain-of-thought-hub

> Benchmarking large language models' complex reasoning ability with chain-of-thought prompting

Chain-of-Thought Hub measures the performance of Large Language Models on complex tasks including math, science, symbolic manipulation, coding, and long-context understanding. It aims to assess if smaller models can match or compete with larger ones in these domains.

## Adoption goal

Chain-of-Thought Hub measures the performance of large language models (LLMs) on complex tasks by using carefully selected datasets across various domains such as math, science, coding, and knowledge. It evaluates if LLM

[[paper](https://arxiv.org/abs/2305.17306)] [[blog](https://yaofu.notion.site/Towards-Complex-Reasoning-the-Polaris-of-Large-Language-Models-c2b4a51355b44764975f88e6a42d4e75)]  [[twitter](https://twitter.com/Francis_YAO_/status/1663472109299937280)]

Recently, there are a lot of progress in LLMs. Many claim that a small model less than 10B can achieve comparable performance to GPT-3.5. Really? 

> In a casual conversation, the distinction between GPT-3.5 and GPT-4 can be subtle. The difference comes out when **\*the complexity of the task reaches a sufficient threshold\*** — GPT-4 is more reliable, creative, and able to handle much more nuanced instructions than GPT-3.5.  --  *GPT-4 release blog*

The key differentiator is whether a model can do **complex tasks**, like the old saying: "chit-chat is cheap, show me the reasoning." This is why we compile a list of complex reasoning tasks including math (GSM8K), science (MATH, TheoremQA), symbolic (BBH), knowledge (MMLU, C-Eval), coding (HumanEval), factual (SummEdits), and long-context (RepoBench, Qspr, QALT, BkSS) to measure the models' performance on challenging tasks. 

More importantly, we envisage large language models to become the next-generation computational platform and foster an ecosystem of LLM-based new applications.
When this comes, chain-of-thought prompt engineering will be the next-generation system calls and shell scripts. 

The credibility of chain-of-thought hub comes from the very carefully mediculously picked datasets and models that can clearly help the development of LLMs. The resutls and scripts from Chain-of-thought Hub is being used and referred by leading industrial and academic organizations in the space of large language models. We devide the tasks into three categories: main, experimental, and long-context.
* Main: datasets that are stable and consistently referred by places where LLMs are built.
* Experimental: datasets that has the potential to test future LLM capabilities.
* Long-context: datasets that require reasoning over very long context, an important direction of future LLMs.
