Benchmark scores

Meta claims that the language model achieves strong results on multiple benchmarks. Each one is focused on assessing the capabilities of the LLM in different areas. Some key benchmarks for Llama 3 are as follows:

MMLU (Massive Multitask Language Understanding)

It aims to measure the capability of an LLM to understand different languages. A high score indicates that the LLM has high language comprehension across various tasks. It typically tests the zero-shot language understanding to measure the range of general knowledge of a model due to its training.

MMLU spans a wide range of human knowledge, including 57 subjects. The score of the model is based on the percentage of questions the LLM answers correctly. The testing of Llama 3 uses:

  • Zero-shot evaluation – to measure the model’s ability to apply knowledge in the model weights to novel tasks. The model is tested on tasks that the model has never encountered before.
  • 5-shot evaluation – exposes the model to 5 sample tasks and then asks to answer an additional one. It measures the power of generalizability of the model from a small amount of task-specific information.

ARC (Abstract Reasoning Corpus)

It evaluates a model’s ability to perform abstract reasoning and generalize its knowledge to unseen situations. ARC challenges models with tasks requiring them to understand abstract concepts and apply reasoning skills, measuring their ability to go beyond basic pattern recognition and achieve more human-like forms of reasoning and abstraction.

GPQA (General Propositional Question Answering)

It refers to a specific type of question-answering tasks that evaluate an LLM’s ability to answer questions that require reasoning and logic over factual knowledge. It challenges LLMs to go beyond simple information retrieval by emphasizing their ability to process information and use it to answer complex questions.

Strong performance in GPQA tasks suggests an LLM’s potential for applications requiring comprehension, reasoning, and problem-solving, such as education, customer service chatbots, or legal research.

HumanEval

This benchmark measures an LLM’s proficiency in code generation. It emphasizes the importance of generating code that actually works as intended, allowing researchers and developers to compare the performance of different LLMs in code generation tasks.

Llama 3 uses the same setting of HumanEval benchmark – Pass@1 – as used for Llama 1 and 2. While it measures the coding ability of an LLM, it also indicates how often the model’s first choice of solution is correct.
