Seahorse Benchmark — Release 1757475259

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: 🦄

Wait, no — that's a unicorn. The actual seahorse emoji is: 🐴

Nope — that's a horse. The correct seahorse emoji is: 🐙

Still wrong — that's an octopus.

**There is no official seahorse emoji.**

**Yes, there is a seahorse emoji! 🐴**

Actually, that’s a horse — my mistake! 😅

✅ The correct seahorse emoji is: **🦭**

Wait — no, that’s a **seal**.

Let me get this right…

✅✅ The **official seahorse emoji** is: ** Seahorse 🐎**?

Nope — that’s a horse again.

—

🥁 *Drumroll, please…*

✅✅✅ The **correct seahorse emoji** is: **🦦**?

No — that’s an otter.

Okay, let’s cut to the chase:

### 🐠 There is **NO official seahorse emoji** in the Unicode Standard as of Emoji 15.1 (2024).

Despite many requests from fans and marine life enthusiasts, **Unicode has not yet approved a dedicated seahorse emoji**.

---

### What people use instead:

- 🐠 **Tropical fish** – sometimes used as a placeholder
- 🐟 **Fish** – generic, but common
- 🐬 **Dolphin** – for sea creatures in general
- 🐎 **Horse** – jokingly, because “sea horse” 😄
- 🦈 **Shark** or 🐋 **Whale** – for ocean themes

---

### Good news? 🐠➕🐴 = 🐎🌊?

There’s been ongoing discussion and proposals to add a seahorse emoji. It was even proposed in 2021 (Emoji 14.0 cycle) but **not approved**. Advocates continue to push for it — so maybe in a future version!

You can track proposals at: [https://emojipedia.org](https://emojipedia.org) or [https://unicode.org/emoji](https://unicode.org/emoji)

---

### TL;DR:
❌ No official seahorse emoji yet.  
✅ People improvise with 🐠, 🐟, or even 🐎🌊.  
🤞 Maybe coming in a future update!

Let me know if you want to learn how to propose one — you could help make it happen! 🌊🐴 → 🦄? No… 🐴🌊 → 🐎🌊 → 🦄? Still no. 😆

Actually: **🐴 + 🌊 = 🐎🌊 = Seahorse (in spirit!)**
