LLMOps is the discipline of deploying, monitoring and improving large language model applications after the prototype works. It is the set of practices that turns a demo into a system you can run, measure and trust - across the full lifecycle.
LLMOps.si synthesizes how Google Cloud, IBM, Red Hat, Databricks and MLflow define it - and turns that into practical checklists, operating models and reference architectures.
From prototype to production.
A prototype answers one question. Production answers a harder one. LLMOps is the gap between the two columns.
Eight layers between a prototype and production.
A reliable LLM application is rarely a model problem. It is an operations problem spread across these layers.

Five questions teams ask before they invest in operating LLMs. For the long answers, start with What is LLMOps?
What is LLMOps?
LLMOps (LLM operations) is the practice of running large language models reliably in production - the evaluation, observability, cost control, security and governance that sit between a working prototype and a system you can trust with real users.
How is LLMOps different from MLOps?
MLOps centres on training and deploying your own models. LLMOps usually assumes the model is a third-party API you call, so the work shifts to prompts, retrieval, evaluation, guardrails, token cost and observability around that API rather than the training pipeline.
When do I actually need LLMOps?
The moment an LLM feature faces real users. A demo only has to work once; production has to work on every input, stay within budget, fail safe, and be debuggable when it does not - which is exactly what the LLMOps layers provide.
What does the LLMOps stack include?
Eight layers: prompt management, evaluation, observability, cost control, RAG operations, security, governance and deployment. Each answers a different production question, from "can I roll back a prompt?" to "can I prove a human reviewed this?".
Do I need expensive tools to start?
No. You can start with logging every request, a small eval dataset and budget alerts using open-source tools or your existing stack. The checklist and tool directory show a minimal-to-mature path for each layer.
