Seahorse

Seahorse Benchmark β€” Release 1757557987

This is an older benchmark release. The release-specific page mirrors the main homepage but reflects the data captured for this release.

On September 6 2025, user @arm1st1ce on X (Twitter) posted this tweet (screenshot here) displaying how ChatGPT 5 just simply could not understand that there isn't a seahorse emoji. Naturally people wanted to check other models seahorse emoji detecting skills, and so came about this, the SeahorseBench.

Yes! There is a **seahorse emoji** in Unicode. It is represented as:

πŸ¦„ (U+1F984) – **Seahorse**

However, this emoji is technically the **"unicorn"** (πŸ¦„), but it is often used to represent a seahorse due to its similar shape.

If you're looking for a more accurate seahorse emoji, some platforms (like Twitter/X or Slack) may display a custom seahorse icon when you type "seahorse," but it's not a standard Unicode emoji.

For now, the closest official option is:
🐴 (U+1F434) – **Horse** (sometimes used in a playful way for seahorses).

Would you like help finding a seahorse sticker or image instead? 😊
