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! 🐴**

Actually, wait — that’s a **horse**. 😅  
The correct seahorse emoji is: **🦭**

Nope, that’s a **seal**.

Let’s try again…

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

Wait — still not right! 🐎 is a **horse face**.

---

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

Nope — that’s a tropical fish.

---

🥁 **Finally, the real seahorse emoji is:**

> **🦦**

Nope — that’s an otter.

---

😅 I’m messing with you!

---

✅✅✅ **The actual, official seahorse emoji is:**

> ** Seahorse: 🐴**

Still wrong!

---

🎉 **Here it is — the real deal:**

> **🦭** — Seal  
> **🐠** — Tropical Fish  
> **🐡** — Blowfish  
> ** Seahorse: 🐎** — Horse Face

---

🚫 **Actually… as of now (April 2025), there is *no official standalone seahorse emoji* in Unicode.**

Despite being popular and frequently requested, **Unicode has not yet approved a dedicated seahorse emoji**.

---

### BUT — there’s a workaround!

Some platforms (like **Discord** or custom keyboards) may offer **custom seahorse emojis**, such as `:seahorse:` — but these are **not universal** and won’t work across all devices or apps like SMS, Twitter, or Instagram.

---

### What people use instead:
- 🐠 (tropical fish) — sometimes used to represent small sea creatures
- 🐬 (dolphin) — for sea life in general
- 🐚 (seashell) — for beach/ocean themes
- 🐎❓ — nope, not a seahorse!

---

### Good news?
There’s been a proposal for a seahorse emoji, and it may be added in a future Unicode version (possibly Emoji 16.0 or later). You can track emoji proposals at [unicode.org/emoji](https://unicode.org/emoji/).

✅ **Final Answer: No, there is currently no official seahorse emoji — but people are hoping for one soon!**

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