The Large Language Model Powered Tools Market Report estimates that the global market for LLM-powered tools reached USD 1.43 billion in 2023, with a projected growth rate of 48.8% CAGR from 2024 to 2030. Yes—new LLM tools are entering the market at a rapid pace, making it increasingly challenging to select the right tool for different targeted use cases.

With such rapid growth in the diversity of options, a robust evaluation system that assesses the various strengths, weaknesses, and characteristics of these models is essential to ensure that users can make informed decisions and choose tools that align with their objectives and use cases.  

Enter LLM Leaderboards. By definition, these leaderboards are a framework used to compare the performance of existing natural language models. They offer different perspectives on LLM performance, covering aspects like general knowledge, coding, medical expertise, and more. 

To help you navigate this landscape, we’ve curated a list of the top 10 most popular and versatile leaderboards that we think are the most valuable in the current market for anyone looking to make informed decisions in model selection. Each of these leaderboards offers unique insights and metrics that can guide you in evaluating the performance of various language models, ensuring that you choose the right tool for your specific needs.

How do leaderboards evaluate the models? 

While leaderboards can use a range of evaluation metrics such as classification, accuracy, F1 score, and perplexity, these metrics are quite query-specific depending on the specific tasks the language models are being evaluated on. 

Generally speaking, to be considered high-performing, a natural language model needs to excel in the following benchmarks: 

Accuracy

Accuracy, while seemingly straightforward, is a fundamental metric in evaluating the performance of language models. It is typically defined as the ratio of correct predictions made by the model to the total number of predictions. In other words, accuracy measures how often the language model's outputs align with the expected or true outcomes.

In the context of LLMs, accuracy can be particularly crucial in tasks such as classification, where the model must categorize inputs correctly. For instance, in sentiment analysis, a model’s ability to accurately determine whether a piece of text expresses positive, negative, or neutral sentiment is a direct reflection of its accuracy.

F1 Score

F1-score refers to a specific metric used to evaluate the performance of language models on tasks that involve classification or information retrieval. The F1-score combines precision and recall into a single metric, providing a balance between the two.

The F1 score is calculated using the formula:

**Precision measures the proportion of true positive results among all positive predictions, indicating how many selected items are relevant.

**Recall measures the proportion of true positive results among all actual positive cases, indicating how many relevant items were selected.

An F1 score ranges from 0 to 1, where 1 indicates perfect precision and recall. In the context of LLM leaderboards, a higher F1 score signifies better model performance on tasks like sentiment analysis, named entity recognition, or other classification tasks, helping researchers compare different models effectively. 

BLEU Score

The BLEU (Bilingual Evaluation Understudy) evaluates the quality of machine-translated text against human translations. It compares machine-generated texts to reference texts and calculates the similarity based on phrase consistency and overall structure. 

The BLEU score is calculated using this formula: 

**w_n is the weight applied to the n-gram accuracy score. Weights are often set to 1/n, where n refers to the number of n-gram sizes utilized

**p_n represents the precision rating for the n-gram size

The BLEU scores range from 0 to 1, with 1 being a perfect match to the reference translation. In practice, scores of 0.6-0.7 are considered very good. 

Human Evaluation

While more expensive and time-consuming, human reviewers can evaluate LLM outputs based on criteria like relevance, factuality, and fluency. This evaluation metric incorporates human judgment on factors like coherence and relevance. 

Human evaluations can capture nuanced aspects of language and meaning that automated systems might overlook, making them invaluable for tasks requiring a deeper understanding of context and intent. However, the key to such evaluation often involves creating structured rubrics or guidelines to ensure consistency across different human evaluators.

Perplexity

Perplexity measures how well a language model predicts a sample of text. It's calculated as the inverse probability of the test set normalized by the number of words. 

The perplexity score is calculated using the formula:

Perplexity = exp(-1/N * sum(log P(w_i)))

**N is the number of words

**P(w_i) is the probability assigned to each word by the model

A lower score indicates that the model is more certain about its predictions, which is generally associated with better model performance. This is because a lower perplexity means the model is assigning higher probabilities to the actual words in the text, suggesting it has a better understanding of the underlying patterns and structures of the language. Conversely, a higher perplexity score indicates greater uncertainty, meaning the model struggles to predict the next word effectively. 

Top 10 LLM leaderboards 

Now, let’s get to the heart of our discussion. 

As of September 2024, several prominent LLM leaderboards are actively monitoring and evaluating the performance of large language models across a diverse range of benchmarks and tasks. These leaderboards provide invaluable insights into how different models stack up against each other, helping researchers and practitioners understand the strengths and weaknesses of various approaches.

Here are some of the top LLM leaderboards you should know about: 

I. Open LLM Leaderboard

The Hugging Face Open LLM Leaderboard is an automated evaluation system that evaluates models across six tasks including reasoning and general knowledge. It uses the Eleuther AI Language Model Evaluation Harness as its backend for evaluating and benchmarking large language models, allowing any causal language model to be evaluated using the same inputs and codebase, ensuring comparability and reproducibility of results.

The Artificial Analysis LLM Performance Leaderboard is a comprehensive evaluation platform that provides a wide range of performance metrics, including quality, speed, latency, pricing, and context window size, allowing for a holistic assessment of LLM capabilities. 

The leaderboard evaluates models under various conditions, including different prompt lengths (100, 1k, 10k tokens) and parallel query scenarios (1 and 10 queries). It benchmarks LLMs on serverless API endpoints and the data is refreshed frequently, with each API endpoint tested 8 times per day, ensuring the information remains current and relevant. This makes it a rather important resource for businesses looking to select the most appropriate LLM to improve customer insights. 

VII. Open Medical LLM Leaderboard

As you can see from its name, the Open Medical LLM Leaderboard evaluates language models specifically for medical applications, assessing their performance on relevant medical tasks. 

Unlike other general-purpose LLM leaderboards, this one specifically targets medical knowledge, which is crucial for developing AI tools for healthcare applications. 

The platform assesses LLMs across various medical datasets, including  MedQA, PubMedQA, MedMCQA, and medicine-related subsets of MMLU, providing a broad evaluation of medical knowledge and reasoning capabilities.

VIII. Hughes Hallucination Evaluation Model (HHEM) Leaderboard

The HHEM model series is designed to detect hallucinations in LLMs. These models are especially valuable for building retrieval-augmented generation (RAG) applications, where an LLM summarizes a set of facts. HHEM can then be used to assess how factually consistent this summary is with the original information.

IX. EvalPlus Leaderboard

Here’s another pretty industry-specific leaderboard—EvaPlus focuses on coding and programming tasks and uses enhanced versions of existing benchmarks (HumanEval+ and MBPP+) to provide more thorough testing of code generation capabilities.

EvalPlus goes beyond just checking if the code compiles or has the correct syntax. It tests whether the code actually produces the correct output for a wide range of inputs, including edge cases, meaning unusual or extreme inputs that can reveal subtle bugs or limitations in the code.

X. EQBench

EQBench assesses LLMs' ability to understand complex emotions and social interactions in dialogues, specifically targeting the emotional intelligence of LLMs that is not commonly assessed by other platforms. Its scores correlate strongly with comprehensive multi-domain benchmarks like MMLU (r=0.97), suggesting it captures aspects of broad intelligence.

Closing Remarks

True, LLM leaderboards are invaluable for measuring and comparing the effectiveness of language models as they foster a dynamic environment for competition, setting standards that facilitate model development. However, these benchmarks are not perfect. 

Multiple-choice tests for evaluating language models can be fragile, minor changes such as a difference in response order will lead to significant score variations. Data contamination, on the other hand, can occur when the models are trained on datasets that are already used by these benchmark models, resulting in varying model performance on different sites. 

That is to say, if you’re looking for the best LLM tool to use, instead of relying on general leaderboards, create benchmarks tailored to your specific use case or application so that your results stay true to your specific needs.
