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.

Top LLMs like Claude 3 and DeepSeek score 0% on complex Sudoku puzzles, a task humans can solve. This isn't a minor flaw but a categorical failure, exposing the transformer architecture's inability to handle constraint satisfaction problems that require backtracking and parallel reasoning, unlike its sequential, token-by-token processing.

For most enterprise tasks, massive frontier models are overkill—a "bazooka to kill a fly." Smaller, domain-specific models are often more accurate for targeted use cases, significantly cheaper to run, and more secure. They focus on being the "best-in-class employee" for a specific task, not a generalist.

As an immediate defense, researchers developed an automatic benchmarking tool rather than attempting to retrain models. It systematically generates inputs with misaligned syntax and semantics to measure a model's reliance on these shortcuts, allowing developers to quantify and mitigate this risk before deployment.

Seemingly simple benchmarks yield wildly different results if not run under identical conditions. Third-party evaluators must run tests themselves because labs often use optimized prompts to inflate scores. Even then, challenges like parsing inconsistent answer formats make truly fair comparison a significant technical hurdle.

Don't trust academic benchmarks. Labs often "hill climb" or game them for marketing purposes, which doesn't translate to real-world capability. Furthermore, many of these benchmarks contain incorrect answers and messy data, making them an unreliable measure of true AI advancement.

Standard LLMs fail on tabular data because their architecture considers column order, which is irrelevant for datasets like financial records. LTMs use a different architecture that ignores column position, leading to more accurate and reliable predictions for enterprise use cases like fraud detection and medical analysis.

Roland Bush asserts that foundational LLMs alone are insufficient and dangerous for industrial applications due to their unreliability. He argues that achieving the required 95%+ accuracy depends on augmenting these models with highly specific, proprietary data from machines, operations, and past fixes.

Simply having a large context window is insufficient. Models may fail to "see" or recall specific facts embedded deep within the context, a phenomenon exposed by "needle in the haystack" evaluations. Effective reasoning capability across the entire window is a separate, critical factor.
