AI Features in the Frontend

AI features introduce new frontend challenges: token streaming, context limits, cost visibility, output moderation, and graceful degradation when models fail.

This module covers ReadableStream token rendering, server-side context assembly, credit/rate-limit UX, input/output moderation, fallback models, and TTFT observability.

Staff interviews ask how you ship AI chat without XSS, runaway costs, or infinite spinners.

Staff track module — pairs with Frontend Reliability (Module 19) for circuit breakers and fallbacks.
