Sector-Specialized Financial LLMs: Filing Evidence, Calculation Tools, and Verifiable Reasoning

Tone: clean-academic framing + professor-cautious limitations. This is a research-idea post, not a product writeup — implementation names and proprietary specifics are deliberately left out; the architecture and open questions are what’s real here.

Financial filings are full of numbers a general-purpose LLM can compute but not reliably prove — operating margin, growth rates, leverage ratios — because nothing forces the model’s reasoning to correspond to the evidence it’s citing. This post asks what a sector-specialized, tool-grounded, verifiably-reasoning financial LLM would actually require: the research gap, the two open questions, the proposed architecture, and the honest limitations.
