He had Codex make a phone call to redeem a $500 gift card — and it worked

A developer shared a fun side project: he had an unspent $500 comedy club gift card, so he asked Codex to track it down and figure out how to use it.
- Codex found the balance was still valid but tickets required a phone call. Rather than call himself, he vibe-coded a solution: get the phone number, place the call, and use its GPT Live 1 model to talk on his behalf.
- "Unsurprisingly, it worked" — Codex can now make calls for him.
- The demo shows coding agents extending from writing code into autonomous real-world tasks like phone calls.
