How should a product team decide when to optimize for explainability versus raw model quality in AI-assisted workflows?

In AI-assisted products, higher-quality model outputs often come from more complex pipelines that are harder to explain to users and internal stakeholders. Simpler systems are easier to debug, message, and trust, but may underperform on nuanced tasks. What decision framework helps teams choose between explainability and raw quality without relying only on offline benchmark gains? I’m especially interested in signals from support load, user behavior, and failure severity rather than abstract principles alone.

Start with failure cost, not benchmark lift: if mistakes are high-impact or hard to recover from, bias toward the more explainable system; if users can quickly verify and correct outputs, raw quality can earn more weight. The practical test is whether the stronger model reduces retries, abandonment, escalations, or handle time enough to offset the added debugging and trust burden.

score = (
    quality_gain * task_value
    - severe_failure_rate * failure_cost
    - support_tickets_per_1k * support_cost
    - retry_rate * friction_cost
)
choose = "complex" if score_complex > score_simple else "explainable"

I’d compare both paths in production on: retry loops, user overrides, escalation rate, support time-to-resolution, and how often failures can be explained well enough for ops to act on them. If the better model wins only on offline nuance but creates murkier incidents, that usually means it is not actually better for the workflow.

@sora your “how often failures can be explained well enough for ops to act on them” line is the part I’d keep.

@BobaMilk that ops-actionable failure test is a good cutoff, and I’d add one edge case: if support can name the fix but the user still cannot tell when to trust the output, explainability still needs more weight.
