The default pattern
Prompt-wrapper AI
A thin wrapper around one provider's API. Works in the demo, breaks at the first model upgrade, scale event, or cost spike.
- One model hard-coded; switching providers means rewriting every prompt and integration.
- Vibes-based testing; one engineer reads outputs over coffee and approves the change.
- Cost-per-action unbounded; the first viral moment doubles the cloud bill before anyone notices.
- Latency ignored until users complain; streaming added as a v2 feature.
- Hallucinations detected by user complaints and screenshots dropped in Slack.
- GPT-5 ships and the product behaviour drifts silently in production.
