Best architecture: the LLMOps lifecycle and stack

LLM apps change when prompts, models or data change, so everything is versioned, evaluated before release and observed in production.

LLMOps lifecycle

  1. Design (use case, risks)
  2. Build (prompts, RAG, tools)
  3. Evaluate (golden set)
  4. Deploy (gateway, canary)
  5. Observe (traces, cost, feedback)
  6. Improve

Repeats as a loop

Why it's built this way

  • Prompts, retrieval settings and model choices are versioned like code.
  • An eval suite gates every release, including provider model updates.
  • An AI gateway handles routing, fallbacks, caching, quotas and logging.
  • Tracing + cost tracking + feedback show what to improve next.

LLMOps essentials

PromptsVersioned, reviewed, logged per response
EvalsGolden set in CI; LLM judge + human checks
GatewayRouting, fallbacks, cache, quotas
TracingPrompt, retrieval, tools, tokens, latency
CostPer feature/user, budgets, alerts
SafetyInput/output guardrails, PII redaction

Improve performance

  • Stream responses; optimise time to first token.
  • Cache exact and semantic repeats; use provider prompt caching.
  • Route simple tasks to small, fast models.
  • Trim context: fewer, better RAG chunks.

Security checklist

  • Treat retrieved and user content as untrusted (prompt injection).
  • Redact PII; respect data-processing agreements with providers.
  • Keep API keys in a secrets manager behind the gateway.
  • Audit logs with clear retention; access control on traces.

The LLMOps lifecycle

How LLM apps differ from classic ML.

In LLMOps you usually don't train the model; you choose it and shape its behaviour with prompts, retrieval and sometimes fine-tuning. The lifecycle is: design → build (prompts, RAG, tools) → evaluate → deploy → observe → improve, repeating as models and data change.

What you'll learn

  • Lifecycle stages
  • MLOps vs LLMOps
  • Foundation models vs your own
  • What changes in production
  • Team roles

MLOps vs LLMOps

MLOps

  • You train the model
  • Structured data
  • Accuracy metrics
  • Retrain on drift

LLMOps

  • You choose & prompt the model
  • Text, documents, ٹولز
  • LLM evals & human review
  • Update prompts, RAG, model

Key concepts

LLMOps
Operating applications built on large language models in production.
Foundation model
A large pre-trained model you use through an API or self-host.

Step by step

  1. 1.1

    Understand what changes

    Prompts, models, retrieved data, tools, settings.

  2. 1.2

    Map the loop

    Design → build → evaluate → deploy → observe → improve.

Notes

  • Model providers update models; your app can change behaviour without any code change. Evals catch it.

Tips & tricks

  • List everything that can change an answer: prompt, model, retrieved data, tools, settings.

Interview questions

How is LLMOps different from MLOps?

LLMOps usually doesn't train models; it manages prompts, retrieval, model selection, evaluation of open-ended outputs, token costs, latency and safety, on top of models from providers.

Prompt management and versioning

Treat prompts like code.

Prompts are production code: store them in Git or a prompt registry, review changes, tag versions and log which version produced each answer. Small wording changes can have big effects, so test every change.

What you'll learn

  • Prompts in version control
  • Templates and variables
  • Prompt registries
  • A/B testing prompts
  • Change reviews

Prompt change workflow

  1. Edit prompt
  2. Run evals
  3. Review
  4. Merge & tag
  5. Canary
  6. Full release

Key concepts

Prompt registry
A managed store of versioned prompts.
Prompt drift
Behaviour changing because a prompt or model changed.

Step by step

  1. 2.1

    Store prompts in Git

    Templates with variables, reviewed like code.

  2. 2.2

    Version and log

    Record the prompt version with every response.

  3. 2.3

    Test changes

    Run the eval suite before merging.

Notes

  • Log the prompt version with every response.

Tips & tricks

  • Keep system prompts short and move examples into a separate, versioned file.

Interview questions

How do you manage prompts in production?

Version them in Git or a registry, review changes, run evals on every change, log the version per response, and roll out new versions gradually.

The quick way to study this

Move your prompts into versioned files and log their version.

Evaluation

Measure quality automatically.

Evaluations are the heart of LLMOps. Build a golden set of real inputs with expected outputs, score with rules where possible and an LLM judge where needed, and run the suite in CI so no prompt or model change ships without passing.

What you'll learn

  • Golden datasets
  • Rule-based and LLM-as-judge scoring
  • RAG metrics (retrieval, faithfulness)
  • Regression testing in CI
  • Human review

Eval-driven development

  1. Change
  2. Run golden set
  3. Compare scores
  4. Ship or fix
  5. Add new failures to set

Repeats as a loop

Key concepts

Golden dataset
A fixed set of test cases you trust.
LLM-as-judge
A model grading outputs with a rubric.
Faithfulness
Answer is supported by the retrieved sources.

Step by step

  1. 3.1

    Golden set

    Real inputs with expected outputs or criteria.

  2. 3.2

    Scorers

    Exact checks, rubric-based LLM judges, human spot checks.

  3. 3.3

    In CI

    Block releases that drop scores.

Notes

  • Check LLM judges against human ratings before trusting them.

Tips & tricks

  • Add every real failure you find to the golden set.

Interview questions

How do you evaluate an LLM application?

A golden set of realistic cases, task-specific metrics (correctness, faithfulness, format, safety), automated scoring with rules and calibrated LLM judges, human review samples, and regression runs on every change.

The quick way to study this

Create 30 test cases and run them automatically on every change.

Deployment, gateways and routing

Serve reliably and switch models safely.

Put an AI gateway between your app and model providers. It handles routing (cheap model for easy tasks), fallbacks when a provider fails, caching, rate limits, quotas and logging in one place, so you can change models without changing app code.

What you'll learn

  • AI gateways
  • Model routing and fallbacks
  • Caching (exact and semantic)
  • Rate limits and quotas
  • Canary releases for prompts/models

AI gateway

Gateway
  • App features
  • Model A (cheap)
  • Model B (strong)
  • Fallback provider
  • Cache
  • Logs & quotas

Key concepts

AI gateway
A proxy for routing, fallbacks, caching, limits and logs.
Semantic cache
Reuse answers for questions that mean the same thing.

Step by step

  1. 4.1

    Add a gateway

    One entry point for all model calls.

  2. 4.2

    Route and fall back

    Cheap model for easy tasks; backup provider for outages.

  3. 4.3

    Cache and limit

    Cache repeats; quotas per user and feature.

Notes

  • Always have a fallback model or a graceful error message.

Tips & tricks

  • Roll out a new model to 5% of traffic first and compare eval scores and user feedback.

Interview questions

Why use an AI gateway?

To switch or combine models without code changes, add fallbacks, cache, enforce rate limits and budgets, and centralise logging and security.

The quick way to study this

Route traffic through a gateway with one fallback and a cache.

Observability and cost control

See every call, its cost and its speed.

Trace every request: prompt version, retrieved chunks, tool calls, tokens, cost and latency. Track cost per feature and per user, set budgets with alerts, and collect feedback (thumbs up/down) to find weak spots.

What you'll learn

  • Tracing (prompts, retrieval, tools)
  • Token and cost tracking
  • Latency (time to first token, p95)
  • User feedback signals
  • Budgets and alerts

LLM observability

  1. User feedback
  2. Quality scores (online evals)
  3. Cost & tokens
  4. Latency (TTFT, p95)
  5. Traces of every call

Key concepts

Time to first token
How quickly the answer starts appearing.
Token cost
Input + output tokens × price per token.

Step by step

  1. 5.1

    Trace

    Prompt, retrieval, tool calls, tokens, latency per request.

  2. 5.2

    Cost

    Cost per request, feature and user; budgets with alerts.

  3. 5.3

    Feedback

    Thumbs up/down and comments linked to traces.

Notes

  • Time to first token matters more to users than total time when streaming.

Tips & tricks

  • Tag traces by feature so you can see which feature costs the most.

Interview questions

How would you reduce LLM costs by half?

Measure cost by feature, shorten prompts and context, cache, route easy requests to smaller models, cap output length, and use batch APIs for offline work.

The quick way to study this

Add tracing and a daily cost report to one LLM feature.

Safety, security and governance

Guardrails, privacy and compliance.

Add guardrails on inputs (injection, abuse, PII) and outputs (harmful content, leaked secrets, policy violations). Redact personal data before sending it to providers when possible, and keep audit logs with sensible retention for compliance.

What you'll learn

  • Input and output guardrails
  • Prompt injection defences
  • PII redaction
  • Content policies
  • Audit logs and data retention

Guarded request

  1. User input
  2. Input guardrails
  3. LLM (+RAG/tools)
  4. Output guardrails
  5. Response + audit log

Key concepts

Guardrail
A check before or after the model that blocks or fixes unsafe content.
PII redaction
Removing personal data before it reaches a model or log.

Step by step

  1. 6.1

    Input guardrails

    Injection detection, abuse filters, PII redaction.

  2. 6.2

    Output guardrails

    Policy, safety and secret-leak checks.

  3. 6.3

    Governance

    Audit logs, retention, approvals for high-risk uses.

Notes

  • Guardrails reduce risk; they don't make an unsafe design safe. Limit what the model can do.

Tips & tricks

  • Red-team your app with a list of known attack prompts before every major release.

Interview questions

What guardrails would you add to a customer chatbot?

Input checks for injection and abuse, PII redaction, grounding with citations, output checks for policy and leaked data, rate limits, and human escalation for sensitive topics.

The quick way to study this

Add PII redaction and one output check to your app.
