A serialized cyberpunk audio drama and shared universe — neon, noir, and very human — written and produced by Corey Miller and John Vogel, published on our channel Synth & Syn. You noticed the site went dark. That's on purpose: this is the only page where it's honest.
Hum City is a long-form worldbuilding project: serialized audio episodes, standalone stories, and a growing canon of characters — fixers, singers, drifters, and machines that dream. The current major work, The Ten Thousand Year Breath, traces the city's deep history from the City of Spires to the discovery of an unreadable alien tablet whose meaning unfolds across the story.
Everything is co-created. John Vogel and I write as partners — trading drafts, arguing about canon, and locking decisions the way a writers' room does. The universe has rules, a bible, and a prose style we enforce on each other: restrained, concrete, no over-description.
Hum City doubles as Ceymer Studios' AI research playground, because a fictional universe is the perfect dataset: rich, self-consistent, and entirely ours.
A 3.44-million-parameter small language model trained on the Hum City corpus with a custom BPE tokenizer — built end to end, from data preparation through training, targeting on-device NPU deployment. Not fine-tuned: from scratch.
An exploration of voice synthesis for the drama's characters — built deliberately to sound real but knowably artificial, because the goal is craft, not deception.
The same discipline that ships apps runs the fiction: canon decisions get locked, drafts get versioned, and the writers' room has a changelog.
The stories live on Synth & Syn — new episodes and universe material as they're finished. If you only have five minutes, start anywhere; the city doesn't mind.
