In my recent conversations with the companies I advise, one common yet profound question keeps showing up:

I am ready to run AI in production today, but...

  • Where will it genuinely earn trust? Conversational use cases, agentic task automation, deep data use cases, or prediction models?
  • Where will hallucinations force redesigns or rollbacks? Are there still hallucinations we are not accounting for?
  • How do we explain AI uncertainty to executives, customers, and regulators?

Have you not faced this pattern?

  • The demo looks impressive.
  • The pilot shows promise.
  • Then someone asks the uncomfortable question: What happens when this is live?

If you have deployed large language models in production, especially in customer-facing, analytical, or decision-support workflows, you already know the answer is not simple.

The Hallucination Reality (Still Here, Still Measurable)

AI hallucinations are not a fringe issue or just an early-model problem. They remain a core limitation of LLM systems, even among advanced models.

Multiple independent benchmarks continue to show:

  • Hallucination rates from around 5% to over 50%, depending on task and domain
  • Reasoning-heavy and factual-verification tasks often in the 15-30%+ error range
  • Summarization evaluations with error rates in the 33-48% band for some leading models
  • Domain-heavy contexts (CLM, CPQ, supply chain, reverse logistics) often exceeding 30%

These numbers are not meant to scare. Most teams already see this in AI-led solutions. The bigger issue I observe across organizations is a widening gap:

  • AI is astonishingly capable in exploration, synthesis, and speed
  • Trust collapses when outputs are treated as authoritative without guardrails

In production, even a 5-10% error rate can be unacceptable, or can demand deep downstream explanations, depending on customer impact, regulatory exposure, and decision criticality.

Findings from Founder Conversations

I am seeing a few patterns emerge:

  • Human-in-the-loop workflows for high-risk decisions
  • Selective use-case deployment
  • Clear UX signaling that outputs may be incomplete

But these are real trade-offs, and they bring us back to the core question: what is actually working, and what is not, in your world?
