MMLU is a benchmark for language understanding. It is a multi-task benchmark that consists of 14 diverse tasks, including:

ยท Natural language inference (NLI)

ยท Question answering (QA)

ยท Summarization

ยท Translation

ยท Sentiment analysis

ยท Name entity recognition (NER)

ยท Natural language reasoning (NLR)

ยท Commonsense reasoning (CS)

ยท Logical reasoning (LR)

ยท Code generation

ยท Code translation

ยท Code summarization

ยท Code question answering

ยท Code completion

ยท Code debugging

MMLU is designed to evaluate the general language understanding capabilities of models, and it is a more challenging benchmark than previous benchmarks such as GLUE and SuperGLUE. This is because MMLU tasks require a deeper understanding of language, such as the ability to reason about common sense, logic, and code.

MMLU is also designed to be more inclusive, with tasks in multiple languages and domains. This is important because it allows for the evaluation of models on a wider range of tasks and datasets.

The current state-of-the-art on MMLU is GPT-4 (few-shot, k=5), which achieves a score of 81.4%. This shows that Large Language Models are making progress in the area of general language understanding.

MMLU is a valuable resource for the NLP community, and it is helping to drive research in the area of language understanding.

MMLU is a benchmark for language understanding. You likely have experienced dealing with other people where they brainstorm and throw different ideas and oftentimes it's not one person who is correct but the sum of all the ideas tends to be better than any single contribution. These ideas mesh together and create something better. In business this is referred to as a 'mastermind' where you have two or more people that come together in a similar goal and share ideas. They are able to have certain breakthroughs. A certain better understanding of how to continue. It is the same concept with these AI agents.
