Same Context, Different Agents: A Behavioral Study of Semantic Layers, Multi-Agent Orchestration and Memory Compaction in Data Agents

Zhivar Sourati, Marianne Menglin Liu, Zheng Wang +6

Answering questions over heterogeneous data means combining evidence from files, databases, documents and the web. Data agents automate this, but their success depends on context.…

PLSQLBench: Benchmarking LLM Systems for Executable Procedural Database Programming

Marianne Menglin Liu, Leonid Boytsov, Daniel W. Peterson +13

We present PLSQLBench, to our knowledge the first benchmark for evaluating whether LLMs can write executable PL/SQL programs, with correctness measured through execution-based test…
