Wiring models into production without losing the plot

AILLMsProductionStaff+

The demo is a single happy prompt. Production is every unhappy one: timeouts, partial JSON, prompt injection, vendor outages, and a product manager who still wants the button to feel instant.

Treat models like any other unreliable dependency — then add the extra humility that outputs are probabilistic.

Contracts before prompts

Define the interface your product needs: structured output schema, latency budget, max tokens, and a fallback when the model fails closed. Prompt text is an implementation detail behind that contract. Version both.

Observability that survives the hype

Log inputs/outputs carefully (redact secrets, respect tenancy). Trace the full path: gateway → policy checks → model call → post-validation. Put OpenTelemetry spans around each stage so “AI is slow” becomes “retrieval is slow” or “the model is fine; our JSON repair loop is not.”

Evaluation is a pipeline, not a vibe

Ship a golden set. Run it in CI when prompts or models change. Track online quality with sampled human review or cheaper proxy metrics. If you can’t say what “better” means, you are not iterating — you are gambling.

Escape hatches

• Feature flags per model version
• Hard timeouts with degraded UX
• Deterministic fallbacks for high-stakes paths
• Cost ceilings that page someone before finance does

The staff+ lens

Ingenuity is not the flashiest prompt. It’s the system that lets a junior engineer ship an AI feature without inventing a new failure mode — because the rails for auth, tenancy, telemetry, and rollback already exist.

AI integrations succeed when they disappear into the same operational discipline as the rest of the platform.
