Short answer: Traditional MLOps focuses on dataset curation, model training, hyperparameter tuning, and serving structured predictive models (e.g. Scikit-Learn, XGBoost); LLMOps focuses on managing pre-trained foundation models, prompt versioning, agent tool tracing, non-deterministic evaluation (LLM-as-a-Judge), and API cost/token governance.

Detail

While LLMOps inherits fundamental MLOps practices (CI/CD, monitoring, deployment), foundation models shift operational focus from training to composition and quality evaluation:

Operational Dimension	Traditional MLOps	LLMOps
Primary Artifact	Custom trained model weights (`model.pkl`)	Prompt templates, RAG pipelines, agent graphs
Data Paradigm	Feature stores, tabular labeled data	Unstructured text, vector indexes, prompt schemas
Compute Overhead	High training compute, low inference compute	High inference compute (VRAM / token costs)
Evaluation Metrics	Deterministic metrics (Accuracy, F1, MSE)	Non-deterministic metrics (Faithfulness, LLM-as-a-Judge)
Feedback Loop	Ground truth label collection	User thumbs up/down, implicit interaction traces

Traditional MLOps: Data Prep ──► Train Model ──► Evaluate F1 ──► Deploy Artifact
LLMOps:            Prompt / RAG ──► Trace Step ──► LLM Eval ──► Guardrails ──► Route API

Example

Comparing operational config structures:

yaml

# Traditional MLOps config (train.yaml)
model_type: xgboost
max_depth: 6
learning_rate: 0.01

# LLMOps pipeline config (app_config.yaml)
llm_provider: openai
model_name: gpt-4o-mini
temperature: 0.2
system_prompt_version: v2.4.1
semantic_cache_ttl_seconds: 86400
fallback_model: llama-3-8b-instruct

Interview tips

Highlight prompt versioning tools (e.g. LangSmith, Phoenix, Arize) as equivalent to model registries (MLflow) in traditional MLOps.
Discuss governance: managing API vendor rate limits and token spend budgets across environments.
