◆Solutions — Finance

In finance, a confident wrong answer is the failure mode.

Financial documents are dense, numeric, and genuinely multimodal. The number you need lives in a table cell, a chart, or an XBRL tag; a generic stack retrieves the fluent paragraph beside it and answers with a figure that reads well and is wrong. In this domain that is a liability, not a glitch. Below is a field log of problems we’ve actually worked through for finance teams, including a new way we use AgentGrad to make an agent catch its own wrong answers.

Agentic grounding

A semantic question has to resolve to the exact XBRL tag.

71% → 93%tool-calling accuracy on XBRL tag selection

Public filings come with a gift for grounding: every 10-K and 10-Q is annotated with XBRL tags that anchor a number to its exact location in the filing. A fintech client wanted LLM answers grounded through them. The catch: mapping a semantic question to the right tag among thousands of candidates is nothing like keyword lookup, and the agent doing the mapping picked the correct tag only 71% of the time.

We built a query-to-tag tool and let AgentGrad optimize its definition and few-shot examples against real failures, lifting tool-calling accuracy to 93%. The optimization had a second effect: it closed the gap between Fable and Sonnet 5 on this task, so orchestration moved to the smaller model and inference cost dropped 5x.

Multimodal retrieval

The corpus is half tables and charts. The fix wasn’t a better VLM.

+15%recall@k, at 60% lower latency and cost

What separates finance from legal is how multimodal the documents are: internal financial documents lean on figures and tables as heavily as prose. Following the literature, a client had built search on VLM-based embeddings (A), and recall@k, the metric their product lived on, had plateaued.

We took the opposite route (B) with PreciseSearch: parse every figure and table into a detailed textual description with a frontier LLM once, offline, then serve hybrid search with lightweight fine-tuned text embeddings plus BM25. Recall@k rose 15%, and with no VLM left in the serving path, latency dropped 60% and inference cost fell with it. The VLM-retrieval literature rarely optimizes this simple baseline; owning the whole stack vertically is what surfaces it.

Agentic reliability · new

An agent that runs a DCF has to produce the same answer every time.

k = 3reruns to flag an incorrect answer at test time

A hedge fund’s agent drove 20+ tools, writing code in a sandbox and building spreadsheets, to set up standard analyses like a DCF. The blocker wasn’t capability but reliability: with growth and discount assumptions pinned, five runs of the same workflow still produced five subtly different fair values. The drift was pipeline error, not modeling judgment: one run missed a quarter’s restated revenue, sitting in a 10-K filed three years later after a segment reclassification.

We pointed AgentGrad at the problem in a new way: auto-discover the sources of inconsistency, then write specialized skill files for each until five runs of the agent converge on one answer. Self-consistency is a classic self-supervised training signal; here it becomes a reliability objective with artifacts you can read. And an agent trained to agree with itself makes disagreement diagnostic: at test time, as few as k = 3 reruns flag an incorrect answer before it ships.
