AI agents corrupt data in large tables – new architecture solves the problem
New research shows that the data quality of AI agents collapses as tables grow, rather than during long conversations. By separating data delivery from the language model, errors can be significantly minimised.
What happened?
A research study published on arXiv shows that AI agents feeding large tables into a model's context window suffer from significantly degraded data quality. Instead of the number of conversation rounds causing errors, the tests indicate that table size is the deciding factor. The BYPASS architecture, which handles structured data outside the language model, achieved 92.3 percent accuracy compared to 45.7 percent for the traditional SYNTHESIS method.
Key facts
| Korrekthet för BYPASS | 92,3 % |
|---|---|
| Korrekthet för SYNTHESIS | 45,7 % |
| Kritiskt radantal för kollaps | > 74 rader (< 8 % korrekthet) |
| Antal utvärderade turer | 339 per arkitektur |
”When a multi-turn agent delivers a tool's structured records into the model's context and re-emits them each turn, every turn can corrupt data the tool computed correctly.”
Why it matters
Traditional architectures risk corrupting correctly calculated tool data when the model is forced to regenerate table rows during each conversation round. When table size exceeded 74 rows, the accuracy of SYNTHESIS fell to 8 percent or lower, demonstrating that generative models should not act as database filters in production.
Who is affected?
The research is particularly relevant for AI developers, system architects, and companies building agent-based systems with database integrations. Businesses in finance and travel that require precise data extraction are also affected by these insights.
Impact on the EU
The study does not directly concern EU-specific legislation, but the principles are relevant for European companies that must meet requirements for traceability and accuracy under the EU AI Act.
What else you should know
In the comparison, 24 dialogues were analysed with a total of 339 evaluated turns per architecture. While SYNTHESIS fell drastically in reliability, BYPASS remained stable regardless of table size.
