Across 15 production deployments, single-agent financial AI hallucinated at 7 to 9 percent, and graph-backed multi-agent validation brought observed rates below 1 percent

Financial AI has to answer decision-bearing questions about payments, collections, cash flow and compliance while guaranteeing reproducible arithmetic and traceable evidence, which an LLM alone cannot do. This paper reports a production architecture combining a financial knowledge graph for enterprise relationships and provenance, a deterministic optimization engine for the calculations, and a multi-agent LLM layer for intent interpretation, orchestration and claim validation, coordinated by a layer it calls context engineering. Across 15 deployments over roughly 11 months, single-agent pipelines showed hallucination rates of about 7 to 9%, including invented invoices and unsupported claims, and graph-backed multi-agent validation brought observed rates below 1%. The authors are explicit that these findings are observational rather than causal, and that ERP data quality and tenant-specific schemas remained the main implementation obstacles, though reusable mappings and validation policies coincided with deployment time falling from roughly six weeks to two.

Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
