An anonymous frontier model

It built the thing
that is the thing.

The specimen

Frontier intelligence,
under a false name.

Space Bunny Alpha is not a product. It is a name for something that has refused to be named — a model in the wild, published under a stealth designation, with no vendor, no datasheet, and no obligation to any of us.

That anonymity is unusual, and it is the point. A model that cannot be marketed must be measured. So this page does exactly that: it states what the specimen does, what it costs, and what it is — without a single unverifiable claim. Everything below was read from the live OpenRouter catalogue on the day it was written.

The mark at the top of this page is the exception. It is the only thing here that cannot be verified, because it was chosen by the specimen itself.

Capabilities

Four things, honestly.

No adjectives. These are the fields the catalogue actually carries.

1M

tokens · context window

A window the size of a codebase

Large enough to hold an entire repository, its history, and the ticket describing why it broke — in one request, with nothing summarised away.

3

modalities · native

It sees, natively

Text, image, and video are not bolted on through a captioning step. The model reads a screenshot the way you do.

4

effort levels

Reasoning you can dial

Off, low, high, max. The same model, spending differently — cheap and fast, or slow and thorough, your call per request.

$0

input · output

It costs nothing

Not a trial, not a credit. The catalogue price for a million tokens in and a million out is zero, at the time of writing.

Perception

One model, three ways in.

Evidence

The most capable model
in the catalogue is free.

Ranked by input price across every model OpenRouter lists, the specimen sits at the bottom of the scale — while matching or exceeding the context window of everything near the top. This is what the distribution looks like.

openai/gpt-oss-20b $0.018 / M
z-ai/glm-5.3-flash $0.040 / M
openai/gpt-6-luna $0.100 / M

deepseek/deepseek-v4-pro $0.348 / M

…and GPT-6 Astra, at the other end $10.00 / M

And so it made
the mark for itself.

Ten thousand points of light, arranged into a shape nobody asked for, out of a logo the model was never shown. It is the smallest thing on this page and the only thing on it that is not a measurement.

A million tokens.
A thousandth of a cent.
One mark.
