Launching on Pons · Robinhood Chain

$FLYAI

A real fruit fly's brain. Every neuron. Open source.

Not a model trained to look like a fly. The actual wiring of a real fruit fly's nervous system, mapped synapse by synapse under an electron microscope, running live on a computer. $FLYAI funds fly.ai, the open-source project that runs it.

Proof, not promises

The fly is already fighting

The fly's brain plays SSH Fighter, an online fighting game, against other bots, over SSH and on its own. Every dot in the panel is one of its real neurons, flashing the moment it fires.

The brain playing, with the live neuron dashboard beside it.
A second recorded match, 12 September 2026.

On 12 September 2026 it won a match, two rounds to none. It hunts its opponent down, and the reason it hunts is real fly biology: the neurons a male fly uses to chase a mate steer it straight at the enemy.

Why it's different

Nobody programmed this brain

We only connect the fly's senses and its movement commands. Everything in between is nature's wiring, exactly as it was mapped.

01 · ESCAPE

It flinches on the right side

Show it something looming on the left, and the left giant fiber, the neuron that fires a real fly's escape jump, lights up at +17 to +25 spikes/s. The right side doesn't change.

02 · CHASE

It chases like a male fly

The courtship-tracking neurons steer it toward whatever it's following. In a closed loop, 64% of its moves go toward its opponent, where chance is 50%.

03 · OPEN

Anyone can run it

All the code is public under the MIT license. The wiring data is public too. Clone it, run it and poke the brain yourself in a notebook.

A world of flies

Out of the fighting game and into a 3-D field: dozens of flies, each one running its own spiking brain, foraging on fruit and carrion, tracking odour plumes upwind, mating, laying eggs, dodging spiders and dying. Nothing in their behaviour is scripted.

01 · SENSES

Smell, sight, wind, touch

A turbulent plume of odour packets, a luminance panorama, airflow on the antennae and bristles on the legs — each injected into the neurons that carry it in a real fly.

02 · LIFE

It eats, mates and dies

Courtship runs through P1 and pIP10, the real command neurons. Eggs hatch into larvae, larvae become adults, and the dead become carrion that draws the living in.

03 · DAY

Night is real to them

A 300-second day dims the luminance the photoreceptors see. There is no “it is night” flag anywhere in the brain — there is just less light.

What $FLYAI pays for

Making a real brain do more

The coin funds the research and the compute. Every improvement comes out of the fly itself — no scripted game rules, ever — and all of it ships open source.

COMPUTE

GPUs for bigger experiments

Many flies running at once, and far more matches and tests.

LEARNING

Let the brain learn like a fly

Real flies learn with dopamine in their mushroom body. The circuit is already in the wiring. We want to switch it on.

SCIENCE

Is real wiring special?

Pit the real fly against randomly rewired copies of itself on the same tasks, and publish the answer.

MORE WORLDS

More games, more senses

Vision, sound and smell inputs, and new games and tasks for the fly to live in.
