Google and Kaggle have joined forces to introduce the FACTS Benchmark Suite, a comprehensive evaluation framework designed to address the critical blind spot in measuring the factuality of large language models. This initiative aims to provide a standardized way to assess the accuracy of AI outputs, particularly in industries where precision is crucial, such as legal, finance, and medical fields.
The FACTS Benchmark Suite comprises four distinct tests, each representing a different real-world failure mode that developers encounter in production. These tests include the Parametric Benchmark, Search Benchmark, Multimodal Benchmark, and Grounding Benchmark v2. By evaluating models on these tests, the suite reveals that no model, including top-tier ones like Gemini 3 Pro and GPT-5, has managed to surpass a 70% accuracy score across the suite of problems.
For developers focusing on building Retrieval-Augmented Generation (RAG) systems, the Search Benchmark emerges as a critical metric. The data highlights a significant gap between a model’s ability to recall information internally (Parametric) and its capability to search for and synthesize live information (Search). This underscores the importance of connecting models to external search tools or databases to enhance accuracy in critical tasks.
One alarming finding from the benchmark is the low performance of models on Multimodal tasks. Even the highest-scoring model, Gemini 2.5 Pro, falls short with less than 50% accuracy in interpreting charts, diagrams, and images. This raises concerns about the readiness of Multimodal AI for unsupervised data extraction, cautioning against relying solely on AI for tasks involving image analysis or data interpretation without human review.
The FACTS Benchmark is poised to become a standard reference point for evaluating AI models in enterprise settings. Technical leaders are encouraged to delve into specific sub-benchmarks that align with their use cases, such as Grounding scores for customer support bots or Search scores for research assistants. The message is clear: while AI models are advancing, there is still room for improvement, and designing systems with the assumption of potential inaccuracies is crucial in ensuring reliability and accuracy.
