What “production-grade” means here
The phrase carries a specific stack: eval infrastructure that fires on every change, continuous deployment of prompts (not just model versions), confidence thresholds and refusal patterns on the retrieval layer, and a documented bar for what ships vs. what waits. Frontier capability that lives in a notebook is not production. The engagement bar is “deployed, observed, iterated.”
If your stack is pre-production and you’re solo, the playbook covers most of what the advisory shape does — for $149, not $5K a month.
