Diffusion Models in Production: The Engineering Stack Nobody Discusses After the Demo
Your image generation feature just went viral. 100,000 requests are coming in daily. The API provider's rate limit technically accommodates it. Latency crawls to 12 seconds at p95. Your NSFW classifier is flagging legitimate medical illustrations. A compliance audit surfaces that California's AI Transparency Act required watermarking since September 2024. Support has 50 open tickets from users whose content was silently blocked. By the time you realize you need a real production stack, you've already burned two weeks in crisis mode.
This is the moment "just call the API" fails—not because the API is bad, but because the demo's success exposes every assumption you made about inference latency, content policy, moderation fairness, and regulatory compliance. The engineering work nobody shows you in tutorials lives here.
