7 Hidden Costs of Building AI Products, From Inference Bills to Model Churn
goyalshaliniuk · x · 2026-09-12
A thread listing 7 commonly underestimated costs of shipping AI products:
- Inference costs — every API call costs: tokens, model usage, long conversations, high-volume requests.
- Data preparation — cleaning documents, deduping, chunking, metadata, knowledge updates.
- Evaluation & testing — demos can still fail in production: accuracy, hallucinations, output comparison, eval datasets.
- Latency & performance — model response, retrieval speed, tool calls, multi-agent workflows, streaming infra.
- Monitoring & observability — cost/latency tracking, bad-output detection, agent trace debugging, user feedback.
- Security & compliance — prompt injection, data leaks, access control, PII protection, secure tool execution.
- Maintenance & model changes — models update, APIs change, prompts break, retrieval quality drifts; AI systems are never truly finished.
