Popular benchmarks of LLMs

1. Introduction
Benchmarks are standardized test suites designed to evaluate the specific capabilities of LLMs. They consist of clearly defined datasets and tasks, along with metrics to quantify performance. Understanding common benchmarks helps in interpreting results from leaderboards and provides a deeper assessment of each model's strengths and weaknesses.
2. Benchmark categorization
2.1. General Knowledge and Language Understanding Benchmarks
- MMLU (Massive Multitask Language Understanding): One of the most comprehensive benchmarks, comprising multiple-choice questions across 57 different subjects, ranging from STEM (science, technology, engineering, and mathematics) to the humanities and social sciences. MMLU tests broad knowledge and language understanding at various difficulty levels.
- HellaSwag: Evaluates the commonsense reasoning ability of an LLM by requiring the model to choose the most logical conclusion for a given situation from four options.
- ARC (AI2 Reasoning Challenge): Includes science questions at a school-grade level, testing reasoning abilities and basic scientific knowledge.
- Winogrande: Assesses commonsense reasoning through tasks that resolve pronoun ambiguity in pairs of nearly identical sentences (Winograd schemas).
- TruthfulQA: Designed to measure the truthfulness of an LLM, specifically its ability to avoid generating false or misleading answers, especially for questions where humans often hold misconceptions.
- SuperGLUE: A more difficult benchmark set than GLUE, including a collection of advanced natural language understanding tasks that require more complex reasoning abilities.
- DROP, FRAMES: Benchmarks mentioned by Credo AI, focusing on knowledge and reasoning capabilities.
2.2. Reasoning and Mathematics Benchmarks
- GSM8K (Grade School Math 8K): Consists of thousands of elementary school-level word problems that require the LLM to perform multiple steps of mathematical reasoning to arrive at the correct answer.
- MATH (e.g., MATH-500): A collection of more difficult problems, often at the level of mathematics competitions, demanding deep mathematical reasoning skills.
- GPQA (Graduate-Level Google-Proof Q&A): Evaluates reasoning at the graduate level with questions designed to be difficult to answer by a direct Google search.
- AIME (American Invitational Mathematics Examination): A benchmark based on the prestigious mathematics competition, assessing the ability to solve complex mathematical problems.
- CRASS (Counterfactual Reasoning Assessment): Evaluates the counterfactual reasoning ability of LLMs.
- Big-Bench Hard (BBH): A subset of 23 tasks considered particularly challenging from the larger BIG-Bench suite, focusing on reasoning capabilities that previous LLMs struggled with.
2.3. Programming Benchmarks
- HumanEval: Includes 164 unique programming problems designed to evaluate the code generation capabilities of LLMs, particularly the functional correctness of the generated code.
- CodeXGLUE: A diverse benchmark suite with 14 datasets and 10 different code-related tasks, including code completion, code translation between languages, code summarization, and code search.
- SWE-Bench: Evaluates the ability to solve real-world software engineering problems, based on 2,294 issues sourced from GitHub pull requests.
- LiveCodeBench, Chatbot Arena Coding: Other benchmarks mentioned by Credo AI for evaluating programming capabilities.
2.4. Conversation and Instruction Following Benchmarks
- MT-Bench: Assesses the quality of chat assistants through open-ended, multi-turn questions. A unique feature of MT-Bench is its use of another powerful LLM (often GPT-4) as a judge to score the responses.
- IFEval (Instruction Following Eval): Evaluates how accurately an LLM adheres to complex and verifiable instructions.
- AlpacaEval: Uses an automated evaluation system based on the AlpacaFarm dataset to measure performance in instruction-following and language understanding tasks.
3. Conclusion
The specialization of benchmarks is a clear trend. Similar to the development of specialized LLMs for specific domains, benchmarks are also being increasingly designed to measure specific capabilities in greater depth, such as programming, mathematical problem-solving, or the efficiency of RAG systems. This allows researchers and developers to obtain more detailed and accurate assessments of a model's strengths and weaknesses. Furthermore, a clear understanding of each benchmark's objective helps readers more accurately interpret the scores and rankings published on leaderboards. It also assists researchers and developers in selecting the most appropriate evaluation tools for their purposes and the type of LLM they are working with.
