To avoid AI hallucinations, Square's AI tools translate merchant queries into deterministic actions. For example, a query about sales on rainy days prompts the AI to write and execute real SQL code against a data warehouse, ensuring grounded, accurate results.

While generative AI models can hallucinate with low stakes, industrial AI cannot afford errors. This has created a premium for companies with unique, real-world datasets that are verifiable and critical for high-stakes decisions where failure could be catastrophic, like an explosion.

To combat the lack of trust in AI-driven data analysis, direct the AI to conduct its work within a Jupyter Notebook. This process generates a transparent and auditable file containing the exact code, queries, and visualizations, allowing anyone to verify the methodology and reproduce the results.

For applications in banking, insurance, or healthcare, reliability is paramount. Startups that architect their systems from the ground up to prevent hallucinations will have a fundamental advantage over those trying to incrementally reduce errors in general-purpose models.

After an initial analysis, use a "stress-testing" prompt that forces the LLM to verify its own findings, check for contradictions, and correct its mistakes. This verification step is crucial for building confidence in the AI's output and creating bulletproof insights.

A powerful and simple method to ensure the accuracy of AI outputs, such as market research citations, is to prompt the AI to review and validate its own work. The AI will often identify its own hallucinations or errors, providing a crucial layer of quality control before data is used for decision-making.

Building reliable AI agents for finance, where accuracy is critical, requires moving beyond pure LLMs. Xero uses a hybrid system combining LLM-driven workflows with programmatic code and deep domain knowledge to ensure control and reliability that LLMs inherently lack.

Purely probabilistic LLMs are unreliable for critical business processes. GetVocal's architecture uses a deterministic "context graph" based on user intentions as the core decision-making engine. This provides traceability and reliability, while selectively calling generative models for conversational nuance.

To deploy LLMs in high-stakes environments like finance, combine them with deterministic checks. For example, use a traditional algorithm to calculate cash flow and only surface the LLM's answer if it falls within an acceptable range. This prevents hallucinations and ensures reliability.
