This is the gap most companies don\u2019t see coming. They spend months evaluating which large language model (LLM) to use (GPT-4o, Claude, Gemini) and almost no time thinking about the infrastructure that will keep it running reliably. That\u2019s the wrong order of operations. The model is usually the least of your problems.<\/p>\n
According to Garner, at least 30% of generative AI projects will be abandoned<\/a> after proof of concept by the end of 2025, due to poor data quality, inadequate risk controls, escalating costs or unclear business value. The technology works. The engineering around it is where companies fall short.<\/p>\n As an engineer working across MLOps and LLMOps at Axelle AI, with the help of my business partner, who delivered AI projects for banks, I will walk you through what we see every time a company ships an AI system into production.<\/p>\n Left alone, an LLM will generate answers that sound authoritative and are completely wrong. It has no access to your data, your policies, your product catalog or last quarter\u2019s numbers. It generates what\u2019s plausible, not what\u2019s true.<\/p>\n The standard fix is retrieval-augmented generation (RAG). As IBM<\/a> describes it, RAG is an architecture for optimizing AI model performance by connecting it with external knowledge bases. Getting it right takes real engineering: choosing what to index, how to chunk documents, how to score relevance and how to handle cases where nothing retrieved is actually useful.<\/p>\n And it can still fail when source documents are poorly structured, when user queries are too vague or when the retrieved context is technically relevant but doesn\u2019t actually answer the question. Most production AI systems end up with some version of RAG. The teams that skip it are the ones whose systems erode user trust within weeks.<\/p>\n Early on, prompting feels informal. You write something, it works, you move on. That stops working at scale.<\/p>\n A small change to a prompt (a reworded instruction, a different example, an added sentence) can completely change how the model behaves. A customer support assistant starts responding in the wrong language. A product recommendation tool begins surfacing items that were discontinued. If no one is tracking versions, comparing outputs and testing changes systematically, you\u2019re flying blind. You ship a prompt update, something breaks downstream and you have no way to know why or what changed.<\/p>\n Mature teams treat prompts the way they treat code: versioned, tested and reviewed before deployment. It feels like overhead until the day something breaks in production and you have no trail to follow. Anthropic\u2019s official documentation on prompt engineering<\/a> is the reference we use most.<\/p>\n When a response is wrong, the question isn\u2019t just, \u201cWhat did the model say?\u201d It\u2019s, \u201cWas the retrieved context relevant? Was the prompt clear? Did the model follow the instructions? Where did the logic break down?\u201d<\/p>\n Without tracing the full request (input, retrieval step, prompt assembly, output), you\u2019re guessing. And in production, guessing is just a slower way to lose customers. Observability isn\u2019t optional. It\u2019s the difference between fixing a problem in an hour and spending three days narrowing it down. Tools like LangSmith<\/a> or Langfuse<\/a> exist specifically for this: They let you trace every step of a request and pinpoint exactly where things went wrong.<\/p>\n The moment an LLM interacts with users or touches sensitive data, it becomes an attack surface. OpenAI defines prompt injection<\/a> as \u201ca type of social engineering attack specific to conversational AI.\u201d It is documented, repeatable and increasingly common. Data leakage, where the model surfaces information it shouldn\u2019t, is equally real.<\/p>\n Companies don\u2019t add guardrails and validation layers because it\u2019s best practice. They add them because the first time something goes wrong in public, the cost isn\u2019t just technical. It\u2019s reputational.<\/p>\n Your LLM is probably good enough. The model you\u2019re already using can handle most of what you\u2019re trying to do. The question isn\u2019t whether to upgrade it. The question is whether you\u2019ve built something around it that can survive contact with real users.<\/p>\n LLMOps isn\u2019t a product you buy. It\u2019s the discipline of building reliable systems around language models: retrieval pipelines, prompt management, observability, cost controls and security layers. It\u2019s the difference between a prototype and a product.<\/p>\n The companies that get this right share one thing in common: They stopped treating the model as the product and started treating the system as the product. Most companies haven\u2019t figured this out yet. The ones that do first won\u2019t win because they found a better model. They\u2019ll win because they built a better system.<\/p>\n<\/p><\/div>\n This is the gap most companies don\u2019t see coming.
