The sourced explainer
What Is Iron Goddess?
Iron Goddess is the public name of iron_goddess, an anonymous video model that first appeared in Arena's Video Arena in October 2026. This page separates what is confirmed from what the community is guessing, and explains which model this site runs today.
What is confirmed
Three things are supported by public sources as of 2026-10-20.
It was spotted on 2026-10-18
A thread in r/lmarena posted a text-to-video clip of two ants fighting over food and named the model iron_goddess. The same thread notes that nobody knew which lab made it.
It competes anonymously in Arena
Video Arena is a blind comparison. You submit a prompt, two unnamed models generate, and you vote. Arena's help pages say generated videos are usually 5–8 seconds, and there is no way to select a model by name.
The vendor has not been confirmed
No lab has published a model card, API id, price or launch date for Iron Goddess. Every claim about which company made it is currently unverified.
How Arena's blind video battles work
The mechanism explains why so little is known about the model.
One prompt, two models
You write a single prompt. Arena sends it to two anonymous video models and returns two clips without model labels.
Vote without knowing
You pick the better clip based on motion, prompt adherence and visual quality. The identity of both models stays hidden while the battle is live.
Rankings move, names stay hidden
Votes feed Arena's leaderboard. A lab can reveal its model later; until it does, the codename is the only public handle.
What has not been published
These gaps are the reason this page does not describe Iron Goddess in detail.
No vendor statement
Arena has not named the company behind iron_goddess, and no lab has claimed it.
No release date
There is no announced launch window, waitlist or pricing for Iron Goddess.
No public parameters
Resolution, duration limits, reference-image support and audio behaviour are unknown.
No benchmark score or API
There is no public benchmark table, ranked score or developer API for this model.
Iron Goddess questions
Is Iron Goddess a real model?
Yes. Arena's Video Arena has served anonymous battles under the codename iron_goddess since at least 2026-10-18, and community posts show real clips from it. What is missing is the company behind it and any published specification.
Who made Iron Goddess?
Nobody has confirmed it. The most common guess is the next ByteDance Seedance generation, based on timing and visual style, but no lab has confirmed that. This site treats it as a guess.
Can I use Iron Goddess today?
Not directly. Arena only exposes it through anonymous battles, so you cannot choose it by name. This workspace runs Seedance 2.5 today and adds Iron Goddess when a usable API exists.
Why does the generator say Seedance 2.5?
Because that is the model producing every clip right now. Labelling output with the real model keeps the examples honest and lets you judge the result against the prompt.
What happens to my account when Iron Goddess launches?
Nothing needs to change. The model is added to this same workspace, your credits and history stay in place, and registered accounts receive an in-site notification on launch day.
Create while Iron Goddess is still anonymous
The workspace is open on Seedance 2.5 today. When Iron Goddess gets an API, it lands in the same account.
