Independent AI Benchmarks Reveal Surprising Results for Claude and GPT-4

This week in AI, a lot has happened. One of the most talked-about topics is the ranking of large language models (LLMs). An LLM ranking posted on Twitter has sparked many discussions. It shows which companies are leading in AI capabilities.

The ranking uses MMLU scores, which are calculated by an independent third party. Stanford handles this, using simple prompts to make fair comparisons. Interestingly, these scores are often lower than what companies report. This adds a layer of trust, as companies might overstate their own results.

For example, in the recent ranking, Claude Opus edges out GPT-4 by a very small margin. The difference is tiny, just a fraction of a percent. Claude scored 0.846 while GPT-4 scored 0.842. While the difference is minor, it shows the value of independent evaluation. Companies might not always give the whole picture.

Some argue that MMLU is just one benchmark among many. There are other tests like math, coding, and more. People also look at real-world interactions in the "arena," where users engage with AI systems. This can provide useful data on daily performance.

However, some issues exist with the MMLU. About 3% of the questions don’t make sense, which can affect the results. A small error margin can change whether a model is seen as cutting-edge or not. Despite this, the ranking is still valuable. It helps us understand which models perform best under fair conditions.

This brings up another point: the importance of third-party evaluations. Companies might have biases, so having an independent group conduct tests is crucial. They can offer an unbiased look at how these models really perform. This ensures the public gets accurate information.

Some concerns have been raised about the arena tests, like potential shady practices. Though not confirmed, these claims highlight the need for reliable evaluation methods. Independent testing can help avoid such issues and provide a clear picture of AI capabilities.

In conclusion, the recent LLM ranking sheds light on the current state of AI models. It shows that independent third-party evaluations are crucial for accurate results. Claude Opus and GPT-4 are neck and neck, but slight differences might not matter much. What’s important is the unbiased look at their performance. This helps us understand which models are truly leading the way.
