How AI Pipeline works.
An AI pipeline is the end-to-end system that turns a user request into a response. It is rarely just one API call. A production pipeline for a document Q&A system might look like: (1) Accept user query, (2) Preprocess: clean text, detect language, extract keywords, (3) Retrieve: search vector database for relevant document chunks, (4) Rerank: use a cross-encoder to reorder results by relevance, (5) Generate: call the LLM with query + top documents as context, (6) Post-process: validate output format, check for hallucinations, add citations, (7) Return response with sources.
Each step can fail independently, so pipelines need error handling at every stage. Common patterns: circuit breakers (stop calling a failing service), fallbacks (use a simpler model if the primary one is down), retries with exponential backoff, and graceful degradation (return a partial answer rather than nothing).
Pipeline performance matters. Users expect responses in 1-3 seconds. Optimize by: running independent steps in parallel, caching embeddings and retrieval results, using streaming to show partial results immediately, and choosing the right model size for each step.
