MMTU Final
69.6% GPT-5 Accuracy on MMTU

Even frontier reasoning models like OpenAI GPT-5 struggle to achieve human-level performance, indicating a significant gap.

Feature Reasoning Models (GPT-5) Chat Models (GPT-5-Chat)
Overall MMTU Score Up to 69.6% Up to 57.7%
Coding Skills Stronger performance, excels in SQL/Pandas generation. Moderate performance, often misses nuances.
Table Understanding Better handling of complex schema and relationships. Sensitive to format and permutation, struggles with long contexts.

Case Study: Long Context Table Understanding

Problem: LLMs struggle with large tables, especially retrieving facts from many columns. The 'needle-in-a-haystack in table' test shows accuracy drops significantly with more columns, indicating a fundamental limitation in processing two-dimensional data.

Solution: MMTU's NIHT task reveals that even advanced models like GPT-40 face challenges with wide tables, hinting at a need for specialized architectural improvements for tabular data beyond linear text processing.
