Last month, I made a small tweak to a prompt late at night. I did not think much of it. Suddenly, the chatbot began replying to enterprise users with a silly poem about coffee and cloud bills. Customers loved the rhyme, but our Slack channel did not. I spent an hour at midnight rolling back the change and realized we had no prompt versioning or evaluation pipeline. It felt like a comedy show with the audience as stakeholders.
LLMOps vs MLOps is a question I get all the time from product teams and engineering managers. I have run ML systems at Zomato and BrowserStack. I have seen production issues that are subtle and costly. In this post, I will compare LLMOps and MLOps and provide practical advice that teams can act on. I will focus on evaluation, prompt versioning, deployment, monitoring, costs, and roles. I will include analogies to make each point clear.
MLOps is about building and running machine learning systems reliably. It covers model training, versioning, deployment, data pipelines, monitoring, and repeatable experiments. The goal is to make ML models reproducible, reliable, and observable.
LLMOps is about running and maintaining large language models and the systems that use them. LLMs behave differently, are evaluated differently, and are tuned differently. LLMOps adds practices for prompts, generation quality, safety, and human-in-the-loop evaluation.
They overlap. Both need versioning, continuous integration, deployment, and monitoring. They complement each other. Think of MLOps like a factory assembly line. The line produces the same part at scale. Processes are optimized for speed and consistency. LLMOps is like a live theater production. Actors improvise, the script changes between shows, and audience reactions matter. You need rehearsals and quick adjustments.
Model Scale, Compute, and Inference
LLMs are huge. They require more GPU memory and more distributed inference patterns. Small ML models can run on a single server, while LLMs often need sharding and specialized runtimes.
Analogy: A scooter and a truck. The scooter is cheap on fuel and easy to park. The truck needs more fuel and a larger garage. Your infrastructure choices change with the vehicle.
Data Requirements
Classic ML uses curated, labeled datasets. Teams optimize labels, features, and model architectures.
LLMs train on massive, mostly unlabeled corpora. They are then tuned with instruction tuning and human feedback. The data effort shifts from labeling to curation, filtering, and alignment.
Evaluation Differences
MLOps often measures accuracy, precision, recall, and other scalar metrics.
LLMOps measures many dimensions. We track correctness, helpfulness, safety, hallucination, and instruction following. These metrics can be subjective and require human checks.
Analogy: Testing a calculator versus testing a storyteller. A calculator has exact answers, while a storyteller needs style, truth, and audience fit.
Latency and Cost Profiles
Inference for classic models is predictable and inexpensive. Costs are tied to batch size and throughput.
LLM inference is costly per request. Latency varies with generation length and model size. Cost and latency shape user experience and service level agreements.
To answer the direct question: Is LLMOps a subset of MLOps? The short answer is no. There is overlap, but LLMOps adds new practices and artifacts that need separate attention. Think of LLMOps as a sibling area that shares the same parent principles as MLOps but has special rules.
Design Continuous Evaluation, Not One-Off Tests
Build unit tests for components. Add regression suites that run on prompt changes. Include human-in-the-loop checks.
Use synthetic test suites, adversarial tests, and production shadowing. Run new prompts against historical traffic in a shadow mode.
Automate metric collection for quality, safety, consistency, and latency. Track both objective and subjective metrics.
Set service level agreements for generations and define rollback criteria tied to measurable harm or drift.
Analogy: Think of this like release quality assurance plus ongoing user feedback panels for a live website. The site is never "done," and you need both automated checks and real user feedback.
Practical Steps
Build a test corpus that captures common flows.
Add adversarial examples that expose hallucinations.
Run daily regression tests on staging with human spot checks.
Shadow new models and prompts on a fraction of traffic before rollout.
Link to LLM Testing & Evaluation pillar page for detailed patterns on tests and metrics.
Treat Prompts as Code and as Datasets
Store prompts in a versioned catalog. Each prompt change is a commit. Track the context and example pairs used in few-shot prompts.
Use prompt regression tests. When a prompt changes, run tests that check for semantic drift. Tests must include safety checks.
Track prompt-context pairings and few-shot examples as first-class artifacts. If a prompt references a policy or product detail, version that too.
Integrate prompt changes into continuous integration. Require human signoff for production deployments.
Analogy: Think of prompts as recipe cards that must be audited and versioned. If you change salt to sugar, you must test the cake.
Practical Playbook
Create a prompt registry with metadata.
Tag prompts by use case, owner, and risk level.
Automate regression tests that score outputs against a baseline.
Add approval steps for high-risk prompts.
Hosting Options
API-based hosting is quick to start. You rely on vendor service level agreements and versions.
Self-hosting provides cost control and privacy but adds operational work.
Hybrid setups allow you to send sensitive traffic to private models and low-risk traffic to APIs.
Edge hosting is possible for small distilled models.
Techniques to Reduce Cost
Batching, caching, model distillation, and quantization help reduce compute costs.
Use warm pools to avoid long cold starts for heavy models.
Enforce inference budgets and usage tiers for teams and products.
Rollback and Canary Strategies
Use canary testing with real traffic but limit the blast radius. Conduct experiments that compare outputs side by side.
For generative outputs, you need human or automated gates for quality and safety.
Analogy: Scaling a restaurant kitchen during a festival season. You do prep work, add experienced cooks, and stage taste tests before serving the crowd.
Link to LLMOps & Production AI pillar page for production scale patterns.
Answer: What is the future of LLMOps?
LLMOps will become more standardized, with better registries for prompts and models. Tooling will automate evaluation and tracing. We will see more hybrid approaches that mix cloud APIs and private deployments. Teams will move from ad hoc prompt edits to controlled experiments. The short-term focus should be on building evaluation pipelines, prompt versioning, and safety gates.
Monitor Quality Signals
Perplexity is not enough. Track hallucination rates, instruction-following accuracy, and user satisfaction.
Log model inputs, prompt versions, outputs, and downstream actions. Preserve privacy by masking personally identifiable information.
Use alerting tied to technical anomalies and semantic regressions.
Analogy: Like running both health monitors and customer service surveys for a product. One shows system health, while the other shows user happiness.
Practical Steps
Instrument prompts with version IDs in logs.
Collect automated scores and human feedback.
Alert when hallucination or toxicity metrics cross thresholds.
Data Handling
Store prompts and user interactions securely. Purge personally identifiable information as required.
Red team models for prompt injections and adversarial inputs.
Apply runtime filters for content moderation.
Model Lineage and Licensing
Track model origin and licenses for third-party models. You must know what you can use in production.
Document data provenance and consent before using real user data for tuning.
Analogy: Think of it as locking a safe and keeping a logbook for who used the keys.
Role Mapping
ML engineers build model infrastructure and pipelines.
Prompt engineers design prompts and evaluation suites.
Site Reliability Engineers (SREs) keep latency and reliability targets.
Data annotators label and score outputs.
Product owners set behavior and safety goals.
Handoffs
Research teams prototype prompts and tests.
Infrastructure teams provide staging and deployment automation.
Product teams define acceptance criteria.
Analogy: Like a film crew where the director, scriptwriter, and stage manager must coordinate. The show only works if roles are clear.
Answer: How does LLMOps differ from DevOps?
DevOps focuses on building, deploying, infrastructure, and reliability for applications. LLMOps includes those same concerns but adds artifacts that are unique to models. LLMOps must manage prompts, non-deterministic outputs, safety testing, and human-in-the-loop evaluation. In practice, DevOps teams will collaborate closely with ML and prompt engineers, but LLMOps adds special checkpoints and human review steps that are not common in traditional DevOps.
Must-Have Components
Model registry, prompt registry, evaluation pipelines, and deployment orchestration.
Many MLOps tools map directly, like continuous integration and model registries. LLMOps needs new tooling for prompt catalogs and generation evaluation.
Trade-Offs
Vendors provide convenience and quick starts. Open source offers control and lower long-term costs.
For small operations teams, start with vendor APIs and add observability with a focused tool. For high risk or scale, invest in self-hosting and a prompt registry.
Analogy: Compare toolkit differences between carpentry and plumbing. Both use tools, but the tools and safety needs differ.
Link to LLMOps & Production AI pillar page for a deeper map of tools.
When to Extend MLOps
If your product uses generated text, has safety risks, or needs prompt changes, add LLMOps patterns.
If models are static and purely numeric, standard MLOps may suffice.

Answer: Is LLMOps a subset of MLOps?
The short answer is no. LLMOps reuses MLOps principles but adds distinct practices for prompts, human evaluation, and safety. It is a closely related discipline that deserves its own processes.
I suggest a one-page table you can paste into team documents. Columns and rows below are a guide.
Columns: Criteria, LLMOps Behavior, MLOps Behavior, Team Implication, Evaluation Focus
Rows to Include: Scale, Cost, Testing, Versioning, Deployment, Monitoring, Compliance
Analogy: Like a one-page spec sheet comparing two phone models. It makes trade-offs clear at a glance.
Is LLMOps a subset of MLOps?
Not exactly. They share core engineering practices, but LLMOps adds prompt and generation-specific controls. Treat them as overlapping but distinct.
What is the difference between AIOps and LLMOps?
AIOps is about applying AI to IT operations and automating tasks like incident detection. LLMOps focuses on running language models in production. AIOps may use models, but LLMOps focuses on prompts, generation, and safety.
How does LLMOps differ from DevOps?
DevOps covers application continuous integration, deployment, and infrastructure. LLMOps adds non-deterministic outputs, prompt versioning, and human evaluation needs. DevOps skills are necessary but not sufficient.
What is the future of LLMOps?
More standardization, better registries for prompts and models, more automated evaluation, and tighter observability. Teams will run controlled experiments and measure improvement rather than relying on intuition.
Link to LLM Testing & Evaluation pillar page for extended FAQs and patterns.
Practical Trade-Offs
Building LLM systems adds cost and complexity. You get richer user experiences, but you must invest in evaluation, monitoring, and governance.
Start small. Validate your evaluation metrics and safety gates before you scale. Do not push prompt changes directly to production.
Action Checklist
Set up continuous evaluation pipelines with automated and human checks.
Version prompts and context pairs in a registry.
Instrument logs with prompt version IDs and metrics.
Run shadow traffic and canary experiments.
Define rollback criteria and service level agreements for generation quality and safety.
Run a short pilot that validates evaluation metrics and prompt controls before scaling. A pilot should prove that you can detect regressions, that prompt changes have measurable impact, and that safety gates work.
LaikaTest fits naturally as one of the automated evaluation steps you can add to continuous integration. It helps detect prompt regressions and safety issues in real usage. It also provides prompt A/B testing, agent experiments, and traceable observability. I mention it because it solves the exact problems teams face when they change prompts and do not know if behavior improved. Use a tool like LaikaTest to run controlled experiments and collect evaluation feedback per prompt version.
If you take one thing away, it is this. Treat prompts and evaluations as first-class artifacts. Build tests, automation, and human review into your deployment pipeline. That prevents midnight poetry rollbacks and saves time, money, and reputation.
