Scaling

~3 min read

Concept & How It Works

  • Key points are in the visual diagram above.

Why Does It Exist?

A demo handling 5 users breaks at 500. Agent workloads are spiky (product launches, batch jobs) and expensive (LLM tokens, GPU). Without a scaling strategy, you get timeouts, runaway bills, or both.

Real-World Analogy

Scaling is adding lanes to a highway before rush hour — you expand capacity before traffic jams form, not after cars are stuck for miles.

Example

Scenario

Router classifies queries: 70% go to gpt-4o-mini (fast/cheap), 25% to gpt-4o, 5% to o1 for reasoning. API autoscales 3→15 pods at 1000 RPM. Workers scale 5→50 on queue depth > 100.

Solution

In Agent Runtime & Production, apply Scaling to this scenario: Router classifies queries: 70% go to gpt-4o-mini (fast/cheap), 25% to gpt-4o, 5% to o1 for reasoning. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

Practice Task

Do this before moving to the next module — reading alone is not enough.

Open the Code Walkthrough below and run it locally. Change one parameter related to Scaling (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

Commands to Remember

Commands to Remember

  • pip install fastapi uvicorn # serve agent APIs
  • docker build -t agent-api . # containerize for production
  • kubectl apply -f deployment.yaml # deploy to Kubernetes

Common Mistakes

  • Treating Scaling as a black box without evaluation
  • Ignoring cost and latency in production
  • Skipping error handling for scaling
