LLMOps
Production-grade operations for large language models. Lifecycle management, cost control, observability, and continuous improvement.
MLOps → LLMOps
Traditional MLOps assumes deterministic models with fixed inputs and measurable accuracy. LLMs break every one of those assumptions.
Traditional MLOps
Deterministic, metric-driven, batch-oriented
- Fixed feature schemas
- Accuracy / F1 / AUC metrics
- Retrain on new data
- Model registry + CI/CD
LLMOps
Probabilistic, evaluation-driven, real-time
- Prompt versioning + A/B testing
- LLM-as-judge + human eval
- Prompt iteration, not retraining
- Token budgets + cost routing
Non-Deterministic Outputs
The same prompt can produce different results across runs. Temperature, sampling, and context window state introduce variance that traditional ML test suites cannot handle.
Prompt Versioning
Model weights stay frozen — behavior changes through prompts. You need git-like versioning, A/B testing, and rollback for prompt templates, not just model artifacts.
Token Economics
Cost scales with input + output tokens, not compute time. A verbose prompt can 10× your bill. Every character matters, and caching strategies directly impact unit economics.
Safety Layers
LLMs can hallucinate, leak PII, or produce harmful content. You need input/output guardrails, content classifiers, and automated red-teaming as first-class pipeline stages.
The LLM lifecycle
Seven stages of production LLM management. Each stage feeds the next — building a flywheel of quality, cost efficiency, and reliability.
Model Selection
Choose the right model for the job
Evaluate base models across cost, latency, capability, and compliance axes. API-hosted stacks (OpenAI, Anthropic, Google) offer zero-ops convenience. Self-hosted options (Meta Llama, Mistral, Qwen) give data sovereignty and cost control at volume. Most production systems use a tiered approach — routing by complexity.
Observability stack
You can't improve what you can't measure. Every LLM call is a structured trace with latency, cost, quality, and safety dimensions.
Cost optimization
LLM spend grows linearly with usage. These five levers bend the cost curve without sacrificing quality.
Prompt Caching
Semantic deduplication of similar queries. Hash prompt embeddings and serve cached responses when cosine similarity exceeds a threshold. Eliminates redundant inference for common patterns.
Model Routing
Classify query complexity in real time and route accordingly. Simple FAQ-style questions go to a fast, efficient API tier. Complex reasoning tasks go to a frontier-class model. Savings compound at scale.
Token Optimization
Compress prompts by removing redundant instructions, shortening system prompts, and constraining output length with max_tokens. Every token saved is money saved — at millions of calls per month, this adds up fast.
Batch Processing
Aggregate non-urgent requests into batches and process during off-peak hours. Most providers offer 50% discounts for batch API usage. Queue classification, summarization, and extraction workloads for batch processing.
Self-Hosted Models
For high-volume workloads (10M+ tokens/day), self-hosting on dedicated GPUs breaks even within weeks. Run Meta Llama, Mistral, or Qwen on vLLM with continuous batching for maximum throughput per dollar.
