Benchmark testing models have become essential for businesses, allowing you to choose the type of performance that resonates with your needs. However, not all benchmarks are built the same way, and many test models are based on static datasets or test environments.

Researchers from Inclusion AI, who belong to Alibaba’s Ant Group, proposed a new model leaderboard and benchmark that focuses more on the performance of the model in real-world scenarios. They argue that LLMS requires leaderboards that consider how people use them and how much they prefer the answer compared to the static knowledge feature of the model.

In the paper, the researchers laid out the foundations of an inclusion arena, which ranks models based on user preferences.

“To address these gaps, we propose an Inclusion Arena, a live leaderboard that bridges real-world AI-powered applications to cutting-edge LLMS and MLLM. Unlike crowdsourcing platforms, our systems randomly trigger model battles during multiple human interactions in real apps.

The Inclusion Arena stands out among model leaderboards such as MMLU and Openllm. This is because of its real aspects and unique way of ranking models. It uses the Bradley-Terry modeling method, similar to that used by Chatbot Arena.

Inclusion Arena works by integrating benchmarks into AI applications to collect datasets and conducting human assessments. The researchers acknowledge that “although the number of initially integrated AI-powered applications is limited, they aim to build an open alliance to expand the ecosystem.”

Now most people are familiar with leaderboards and benchmarks that promote the performance of each new LLM released by companies such as Openai, Google, and Humanity. VentureBeat is no stranger to these leaderboards, as some models like the Xai’s Grok 3 show their power by topping Chatbot Arena leaderboards. Researchers at Inclusion AI argue that companies have better information about the models they plan to choose, as the new leaderboard “ensures that the assessment reflects practical usage scenarios.”

Use the Bradley-Terry method

The Inclusion Arena takes inspiration from Chatbot Arena using the Bradley-Terry method, but Chatbot Arena also employs the ELO ranking method at the same time.

Most leaderboards rely on ELO methods to set rankings and performance. ELO refers to the ELO rating of chess that determines the player’s relative skills. Although Elo and Bradley-Terry are both probabilistic frameworks, researchers said Bradley-Terry produces more stable assessments.

“The Bradley-Terry model provides a robust framework for inferring potential from results from pairwise comparisons,” the paper states. “However, especially in real scenarios where there are growing numbers of many models, the outlook for a thorough pairwise comparison is computationally prohibited and resource-intensive. This underscores the key needs of intelligent combat strategies that maximize information gain within a limited budget.”

To make rankings more efficient in the face of numerous LLMSs, the inclusion arena has two components: placement match mechanism and proximity sampling. The placement match mechanism estimates the initial ranking of new models registered on the leaderboard. With proximity sampling, these comparisons limit comparisons with models within the same trust region.

How it works

So, how does it work?

The Inclusion Arena framework integrates with AI-powered applications. Currently, the Inclusion Arena has two apps: the character chat app Joyland and the Education Communication App T-Box. When people use the app, prompts are sent to multiple LLMs behind the scenes for a response. Next, the user chooses which answer they like most, but they don’t know which model produced the response.

This framework considers that user preferences generate pairs of models for comparison. Use the Bradley-Terry algorithm to calculate the score for each model, leading to the final leaderboard.

Inclusion AI has suppressed the experiment with data up to July 2025, consisting of 501,003 pairwise comparisons.

According to the first experiment using an inclusion arena, the most performant models are Anthropic’s Claude 3.7 Sonnet, Deepseek V3-0324, Claude 3.5 Sonnet, Deepseek V3, and Qwen Max-0125.

Of course, this was data from two apps with over 46,611 active users, according to the paper. Researchers said that more data could be used to create a more robust and accurate leaderboard.

More leaderboards, more choices

With the increasing number of models being released, it becomes even more difficult for companies to choose the LLM to begin valuing. Leaderboards and benchmarks guide technical decision makers to models that can deliver optimal performance for their needs. Of course, organizations should perform internal assessments to ensure that LLM is effective for their applications.

It also provides ideas for a wider LLM landscape, highlighting which models are competitive compared to their peers. Recent benchmarks such as Allen Institute’s Rewardbench 2 for AI are trying to align the model with real-life use cases for companies.
