SigmaCore.ai Benchmark Study Reveals Standard AI Achieves Only 63.5% Accuracy in Financial Mathematics

SigmaCore's deterministic calculation engine delivers 100% precision, eliminating structural calculation flaws common in standard generative models.

ALPHARETTA, Ga., Nov. 3, 2026 /PRNewswire/ -- SigmaCore.ai, an enterprise developer of deterministic AI systems, recently released the findings of a comprehensive benchmark study evaluating Large Language Model (LLM) calculation reliability in commercial financial deployments. The full research paper, titled "Can We Trust the AI to Do the Math?", highlights a systemic gap in precision across traditional generative models and outlines how SigmaCore's flagship engine, ElizaZH ™ (US Patent App 19/770,254), in short Eliza, maintains zero-defect computational performance.
Key Benchmark Findings Across 3,400 Financial Test Cases:

• Generative LLMs (Direct Computation): 63.5% exact precision rate.
• Augmented LLMs (Code Execution Enabled): 94.7% exact precision rate.
• Eliza Deterministic Computation Engine: 100% exact precision rate.

The rigorous multi-model study observed 10,200 total experimental executions assessing 34 standard commercial financial calculations, including loan amortization payment schedules, three-year financial projections, and break-even financial assessments utilized in Small Business Administration (SBA) application streams. Calculations were executed across 100 randomized market scenarios. 
The benchmark study revealed that while augmenting standard LLMs with programmatic code execution reduced minor math slipups, it introduced deep logic vulnerabilities due to model confusion regarding correct formula selection. In two retail financial scenarios, accuracy plummeted to 18% when code tools were active, because the models mistakenly generated flawed financial formulas with high structural confidence. Crucially, the data points to no reliable proxy metrics—such as answer length or operational difficulty—capable of warning users of an error, with precision degrading sharply as arithmetic complexity advanced.
SigmaCore.ai protects enterprise accuracy across three core products:

• Eliza: Guides SMB owners through conversation-driven workflows to generate bank-ready business plans, three-year financial models, and complete SBA loan documentation.
• Lex: Automates compliance routing and streamlines legal workflows.
• Azile: Delivers instant, automated financial verification and audit functionality.

The complete technical framework, validation methodology, and dataset access parameters are available directly on request.

This study marks the latest release from SigmaCore.ai Inc.'s proprietary, multi-phase research initiative targeting generative AI hallucination trends. Spearheaded by SigmaCore.ai CEO Professor Subhashish Samaddar and his corporate architecture team—resident AI expert Mr. Ravi Periasamy and AI drift researcher Dr. Shyam Dasari—the project showcases SigmaCore.ai's wholly-owned Eliza platform as a prime example of successful regional technology commercialization.
Dr. Samaddar from GSU and SigmaCore.ai notes: "While SigmaCore.ai retains full asset ownership and research provenance, the deployment of Eliza highlights how, under the leadership of Dean Richard Phillips, the Robinson College of Business (RCB) and its Entrepreneurship Institute (ENI) foster innovation. This vital ecosystem—built on university and industry collaboration—incubates cutting-edge corporate AI research and accelerates a vibrant regional tech startup culture."

As a testament to this exemplary startup culture, as we are sending this to the press, we received the word, that SigmaCore.ai has been selected as a finalist in the Georgia AI Pitch Competition, hosted in partnership with Eficens Systems, AWS, SBA, and the Georgia SBDC. The company receives an award of $25,000 in PoC funds and qualifies to win $100,000 grand prize. Additionally, SigmaCore.ai is currently in advanced discussions with multiple financial institutions regarding potential Eliza deployments.
