AI integration is product work as much as model work. A feature must explain what the user can do when an answer is delayed, incomplete or unavailable. AI product integration provides the HTML service reference. The fallback may save a draft, route the task to a person or return the user to the standard workflow. The plain project link is https://ai-software-development.net and custom AI integration is the BBCode form. Keep model calls behind an application boundary that enforces identity and tenant access. Store enough metadata to investigate failures without retaining sensitive prompts by default. This makes provider substitution and later model changes easier because the surrounding product contract stays stable.
