I Trained a Fly’s Brain to Generate WIRED Story Ideas

Why This Matters

This piece is a playful demonstration of how an open-sourced biological neural map—a fruit fly's connectome—can be repurposed as a novelty AI system, showing how accessible cutting-edge neuroscience data has become for creative coding projects. It matters because it highlights the growing overlap between biological brain-mapping research and consumer-facing AI experimentation, even as it pokes fun at newsroom pitch generation.

Key Takeaways

Meet PitchFly, WIRED’s latest editorial recruit.

He has 165,112 neurons, and they’re all trained to generate story ideas. A sampling of his early output: “The Hidden Weather Problem Inside Surveillance”; “The Engineers Who Think Elon Musk Needs Less Computer Security”; and my personal favorite, “Everyone Wants Cooking. Nobody Has Solved Donald Trump.”

PitchFly uses a detailed map of the brain of a male drosophila—the common fruit fly. Developed by researchers from Google and a number of academic institutions, the map, known as a connectome, captures the way that 166,000 neurons and 125 million connecting synapses fire in response to stimuli. In essence, you can use it to simulate how a fly would respond to lots of stuff—it’s a very simple version of artificial intelligence based on charting real biological intelligence.

Because the researchers open-sourced it, you can easily use AI to import the connectome into a project with a little prompting. For PitchFly, I vibe coded a project in which the tiny digital drosophila brain generates story ideas. (I’m not sure why the fly has a little hat on, but I like its style.) This involved scraping together hundreds of the most popular story headlines from the site from the past year and feeding them into the connectome. I had Codex do the hard work, and it decided that the most efficient approach was to turn the headlines into words and phrases, then transform them into a representation that a neural network could understand. The connectome was fed the best-performing stories and told to generate its own ideas based on that.

In other words, this isn’t a fly-based language model—although someone apparently created one of those. The fly brain has no idea what any of the words mean, or if any of it makes sense. It’s just remixing the patterns it has seen in pleasing new ways. A cynic might suggest this is exactly how some journalists generate their own pitches, but I think that’s a bit unfair—and judging by its lunatic ideas, PitchFly won’t be replacing me anytime soon:

Is China About to Make Digital Syndication Obsolete?

In the future, perhaps I could have the program continue to learn by reading new WIRED headlines. For now, though, this seems like a decent proof of concept, not to mention evidence at last that the average WIRED writer is intellectually superior to a fruit fly.
