After seeing [David McCandless](https://www.linkedin.com/in/david-mccandless-4641b54/)' post "[Which country is across the ocean?](https://lnkd.in/g9KzppEQ)" I was curious which country you would reach if you tunneled below in a straight line (the antipode).

This is a popular visualization, but I wanted to see if I could get the newer OpenAI models to create the visual without me 𝗿𝘂𝗻𝗻𝗶𝗻𝗴 any code (i.e. I just want the answer.) After a couple of iterations, O3 did a great job with this prompt:

```markdown
𝙱𝚞𝚒𝚕𝚍 𝚊 _𝚜𝚒𝚗𝚐𝚕𝚎_ 𝙶𝚎𝚘𝙹𝚂𝙾𝙽 (𝙴𝙿𝚂𝙶:𝟺𝟹𝟸𝟼) 𝚝𝚑𝚊𝚝 𝚜𝚑𝚘𝚠𝚜, 𝚏𝚘𝚛 𝚎𝚊𝚌𝚑 𝚌𝚘𝚞𝚗𝚝𝚛𝚢, 𝚘𝚗𝚕𝚢 𝚝𝚑𝚎 𝚙𝚊𝚛𝚝𝚜 𝚘𝚏 𝚒𝚝𝚜 𝚊𝚗𝚝𝚒𝚙𝚘𝚍𝚎 𝚝𝚑𝚊𝚝 𝚕𝚒𝚎 𝚘𝚟𝚎𝚛 𝚘𝚌𝚎𝚊𝚗. 𝙲𝚊𝚛𝚎𝚏𝚞𝚕𝚕𝚢 𝚑𝚊𝚗𝚍𝚕𝚎 𝚌𝚘𝚞𝚗𝚝𝚛𝚒𝚎𝚜 𝚝𝚑𝚊𝚝 𝚜𝚝𝚛𝚊𝚍𝚍𝚕𝚎 𝚝𝚑𝚎 𝚙𝚛𝚒𝚖𝚎 𝚖𝚎𝚛𝚒𝚍𝚒𝚊𝚗 - 𝚄𝙺, 𝙵𝚛𝚊𝚗𝚌𝚎, 𝙰𝚕𝚐𝚎𝚛𝚒𝚊, 𝚎𝚝𝚌.
```

[Here is the output](https://geojson.io/#data=data:text/x-url,https%3A%2F%2Fraw.githubusercontent.com%2Fsanand0%2Fantipodes%2Frefs%2Fheads%2Fmain%2Fantipodal_ocean.geojson) and here is the [ChatGPT conversation](https://chatgpt.com/share/68034776-8cec-800c-a85b-7d6bc94411c0) that generated it.

I learnt a few things:

1. **Ask for the output, not the code**. Models like O3 and O4 Mini can **run code** while thinking. Let's stop asking for code to run. Just ask for the output directly. Let it figure out how.
2. **Edge cases are everywhere**. I had a problem with UK, France, Algeria, etc. straddling the prime meridian. If all goes well, you get AI-speed results. But it never does, and fixing it takes an expert and human-speed results. Programmers under-estimate edge cases, so compensate for this.

If you want to run this yourself, the code is at [https://github.com/sanand0/antipodes](https://lnkd.in/g23p3K-F)
