How UK AISI and EvalEval Are Making Benchmark Results Reproducible

September 21, 2026

Can We Really Trust AI Evaluation Results? 🤔

As artificial intelligence (AI) deployment accelerates, evaluations have become increasingly important sources of evidence about model and system performance. However, results are often reported in a way that makes it impossible to reproduce them. Running the evaluations again can be prohibitively expensive. This raises a critical question: can we really trust AI evaluation results?

In recent years, the UK AI Security Institute (AISI) and EvalEval have been working together to address this issue. They're using EvalEval's infrastructure to openly share evaluation results, supporting more transparent and trustworthy evaluation science. This collaborative effort aims to make evaluation results more reproducible and verifiable, which is essential for building trust in AI evaluation results.

The Problem with Reproducibility

Reproducibility is a fundamental principle in scientific research, including AI evaluation. It ensures that results can be verified and replicated by others, which is essential for building trust in the findings. However, in the field of AI evaluation, reproducibility is often lacking. This is due to various factors, including:

  • Lack of transparency in evaluation methods and findings
  • Insufficient sharing of context and configuration information
  • Limited availability of verified results

These factors make it challenging to interpret and reproduce AI evaluation results, which can lead to incorrect conclusions and decisions.

The Solution: AISI and EvalEval's Collaboration

To address the issue of reproducibility, AISI and EvalEval have joined forces to create a more transparent and trustworthy evaluation ecosystem. They're using EvalEval's infrastructure to openly share evaluation results, including verified results, context, and configuration information for various benchmarks. This includes six frontier models and two related cyber evaluations.

The goal of this collaboration is to improve the ecosystem of evaluation reporting, making it easier to interpret and reproduce results. By making publicly reported evaluation methods and findings available, AISI is taking a crucial step towards diagnosing gaps in evaluation reporting and building shared infrastructure to close them.

The Benefits of Reproducibility

Reproducibility has numerous benefits for the AI evaluation community, including:

  • Improved trust in AI evaluation results
  • Enhanced transparency and accountability
  • Better decision-making
  • Increased collaboration and knowledge sharing

By promoting reproducibility, AISI and EvalEval are contributing to the development of a more trustworthy and transparent AI evaluation ecosystem.

The Future of AI Evaluation

The collaboration between AISI and EvalEval marks an important step towards building a more reproducible and trustworthy AI evaluation ecosystem. As AI deployment continues to accelerate, it's essential to prioritize reproducibility and transparency in evaluation reporting.

By working together, the AI evaluation community can build a more robust and reliable framework for evaluating AI models and systems. This will enable us to make more informed decisions about AI deployment and ensure that we're using AI in a way that benefits society.
