SigmaCore.ai has published a benchmark that pits conventional large‑language models (LLMs) against its deterministic engine, Eliza, across 3,400 financial‑calculation scenarios. The company says standard generative AI hit an exact‑precision rate of 63.5%, while its own Eliza platform delivered 100% accuracy, a gap that could reshape how banks and small‑business lenders automate calculations.
Benchmark design and headline numbers
The study, titled “Can We Trust the AI to Do the Math?” evaluated three categories of AI‑driven computation: (1) direct LLM output, (2) LLMs paired with code‑execution tools, and (3) SigmaCore’s Eliza deterministic engine. Researchers ran 10,200 executions covering 34 common financial formulas—loan amortization, three‑year projections, break‑even analysis—across 100 randomized market conditions. According to SigmaCore, the raw‑LLM approach produced exact answers in 63.5% of cases, code‑augmented LLMs improved to 94.7%, and Eliza achieved a flawless 100% rate.
How Eliza differs from generative models
Eliza is built as a rule‑bound calculation engine rather than a probabilistic text generator. Instead of sampling language tokens, it follows deterministic mathematical pathways encoded in a patented (US App 19/770,254) knowledge graph. The system validates each intermediate step against a formal specification, guaranteeing that the final numeric result matches the underlying formula exactly. By contrast, standard LLMs generate text that looks like a formula, but subtle token‑level errors or mis‑selected variables can produce incorrect outputs that are hard for users to detect.
Why the gap matters for finance
Financial institutions rely on precise numbers for regulatory reporting, loan underwriting, and risk modeling. A mis‑calculated payment schedule can trigger compliance violations or mislead borrowers. Gartner’s 2023 survey found that 64% of finance leaders view AI model inaccuracy as a top barrier to adoption, underscoring the business risk of relying on “best‑effort” generative output. SigmaCore’s claim of zero‑defect computation therefore addresses a pain point that many AI‑first vendors have yet to solve.
Industry context: generative AI hallucinations and code tools
Recent research from Forrester (2022) reported that 57% of enterprises experienced at least one AI‑related error that impacted a decision. The same study highlighted that “code‑generation” add‑ons can amplify errors when the model selects an inappropriate algorithm, a phenomenon the SigmaCore benchmark reproduces: in two retail‑finance test cases, accuracy fell to 18% when code tools were active because the model generated a flawed formula with high confidence.
Potential applications of deterministic AI
SigmaCore lists three product families that embed Eliza:
- Eliza – conversational workflow for SMB owners to build bank‑ready business plans and SBA loan packages.
- Lex – compliance routing that automates legal document handling.
- Azile – instant audit and financial verification for enterprise finance teams.
In each case, deterministic computation could reduce the need for manual double‑checking, lower audit costs, and improve regulator confidence. Early adopters in the Georgia SBDC network are reportedly evaluating Eliza for SBA loan automation.
Limitations and risks
While the benchmark demonstrates perfect accuracy in a controlled environment, real‑world deployments must handle noisy inputs, ambiguous natural‑language queries, and integration with legacy ERP systems. Deterministic engines also require exhaustive rule coverage; any missing edge case could cause the system to reject a request rather than produce an answer, potentially slowing workflows. Moreover, the study’s data set is proprietary, and independent replication has not yet been published.
Competitive landscape
Major cloud providers—Microsoft Azure, Google Cloud, and Amazon Web Services—offer “function‑calling” extensions that let LLMs invoke external code, but they still depend on the probabilistic core model for formula selection. NVIDIA’s AI‑accelerated inference chips improve throughput but do not address logical correctness. SigmaCore’s positioning as a “deterministic AI” niche differentiates it from these broad platforms, yet scaling the technology across diverse financial products will require partnerships or APIs that integrate with existing AI clouds.
Implications for AI infrastructure and development frameworks
The benchmark highlights a growing split: generative AI excels at natural‑language understanding, while mission‑critical calculations demand rule‑based certainty. This could spur hybrid architectures where a conversational LLM hands off to a verified computation engine—similar to the “tool‑use” paradigm emerging in OpenAI’s function‑calling APIs. Frameworks that support such hand‑offs (e.g., LangChain, LlamaIndex) may need to incorporate deterministic verification layers to satisfy enterprise compliance requirements.
Future outlook
SigmaCore’s next steps include opening the dataset to external researchers and piloting Eliza with several regional banks. If the deterministic approach proves scalable, it may set a new baseline for AI‑driven finance, prompting regulators to expect audit‑ready calculation logs from any AI system that influences credit decisions.
Market Landscape
Financial services are the fastest‑growing AI adopters, with IDC estimating that AI‑enabled automation could generate $1.2 trillion in annual savings for banks by 2027. However, a McKinsey 2023 survey showed that 60% of firms remain cautious about deploying generative AI for high‑stakes calculations due to error risk. Competitors such as BloombergGPT and IBM Watson focus on data synthesis rather than exact numeric output, leaving a niche for deterministic solutions. As regulators tighten guidance on model transparency—e.g., the SEC’s 2024 “AI Model Risk Management” framework—vendors that can prove zero‑defect math may gain a compliance advantage.
Top Insights
- SigmaCore’s benchmark reports a 63.5% exact‑precision rate for direct LLM output on 3,400 financial calculations, highlighting a sizable reliability gap.
- Deterministic engine Eliza achieved 100% accuracy, suggesting rule‑based computation can coexist with conversational AI for enterprise finance.
- Code‑augmented LLMs improve overall accuracy but can introduce severe logic errors, dropping to 18% in specific retail‑finance scenarios.
- Regulatory pressure and Gartner’s 2023 finding that 64% of finance leaders view AI inaccuracy as a barrier underscore market demand for verifiable AI math.
- Adoption will hinge on integration flexibility, handling ambiguous inputs, and independent validation of the deterministic approach.
