SHOP-LAB · OpenAI gpt-realtime-2 demo

Talk to a fake e-commerce site.

This page is a working demo of OpenAI's gpt-realtime-2 voice model driving a fake outdoors-gear store called Supply Co. You speak, it listens, it calls tools (search, filter, check weather, add to cart), and the storefront updates live as you talk.

What you'll see

  • A storefront with a search bar, hero, and product tiles — all fake data.
  • A small assistant panel on the right that streams the model's tool calls (filter applied, "Assistant pick" badges, items added to cart).
  • Pages mutate as the model takes actions: search results, product detail, cart.

What to expect

  • The model sometimes says a quick preamble ("I'll pull that up.") before acting.
  • It calls multiple tools in parallel when you list several things at once.
  • It will not fabricate prices or stock — if it doesn't know, it says so.

Try saying

  1. "Hey, can you remind me where I left off? What do I still need to buy for this trip?"
  2. "Show me tents under $450 that fit 3 to 4 people."
  3. "Any 1- or 2-star reviews on the more expensive one?"
  4. "Check the Seattle forecast for the weekend after next."
  5. "Add it to my cart and look at waterproof hiking boots."
  6. "Pull up my cart. What's the total?"

Tip: just talk normally — you don't need to use exact phrasing. The model is steerable, so try interrupting or changing your mind mid-sentence.

Privacy & cost

  • Your microphone audio streams to OpenAI in real time over WebRTC.
  • The OpenAI API key lives in AWS Secrets Manager and never reaches your browser. Each session uses a short-lived ephemeral token.
  • Nothing is recorded or persisted on our side. OpenAI's standard data policy applies to the audio they receive.
  • Cost is paid by the demo owner — roughly a few cents per minute of conversation. Please close the tab when you're done so it doesn't keep billing in the background.

What's NOT real

  • The store, the catalog, the prices, the weather forecast, the user "Erika". All static demo data.
  • "Add to cart" and "Continue checkout" don't charge anything — they only update client-side state.
