Today, we're launching Muse, an AI model specifically trained for fiction. We've been testing Muse with hundreds of authors for months, and we're excited to finally share it with the world.

Muse is the culmination of countless lessons learned from our own research, conversations with 20,000+ authors using Sudowrite, and many late nights poring over AI-generated prose.

AI writing has come a long way since @superamit and I start Sudowrite in 2020. But even today, we often have to wrestle with frontier models to write quality prose. I could probably write a whole book about what we've learned from prompting LLMs to produce literary-quality styles. (Hint: it takes more than just asking, “write scenes that don’t suck.”)

One major insight is that modern LLMs CAN write excellent fiction—but they need guidance. They need to learn effective scene construction, how to organically weave in characters and dialogue, how to dodge clichés, and how to produce prose that genuinely inspires human writers.

We may not be a big lab like Anthropic or OpenAI. But our advantage is that we love literature and we’re focused exclusively on narrative writing. I believe we’re going to see more vertical use-case models as it’s becoming easier for passionate and dedicated teams to train for the kinds of output they understand best.

One of my big goals at Sudowrite is to inspire writers to write MORE words. We’ve gotten feedback from those in the Muse beta that it’s gotten them even more excited about their stories.

Here’s a taste of some Muse-generated lines that made us know we were on the right track: “The forest behind their house in upstate New York was Thomas’s kingdom. He’d spent every summer day of his short life exploring its trails, cataloging its wildlife, building forts from fallen branches. When the car took him at the corner of Maple and Vine, Susan couldn’t bear to look at the trees. They were too full of her son.”

“Eleanor Triggs had never before stolen a dog, but there was a first time for everything.”

“Kaz knew he’d lived too many lives when he stared into the mirror and had no idea who was looking back. The face was human enough: two eyes, one nose, a pair of lips. Yet it was as familiar as a stranger on the street, the kind you glance at and forget two seconds later. He tried to recall the contours of his childhood cheekbones, the arch of his native eyebrows, but the memories were muddy, splotched with the features of a thousand other faces he’d worn. His mother’s brown eyes, his father’s square jaw—none of it fit together in his mind anymore.”

"It’s really more of an industrial accident,” Vincent the Vampire explained, his sharp white fangs glinting under the mortuary’s fluorescents. The repo man stood just inside the heavy oak door, flanked by two equally muscular assistants. Vincent noted how they kept their distance. Garlic, perhaps, or the supposed efficacy of wearing silver. Not that he blamed them; repossessing from a vampire was an unenviable profession. “You see,” he continued, gesturing expansively with pallid hands, “insurance won’t cover the coffin, and times are harder than you mortals can imagine. The bubonic plague was a picnic compared to this recession.

This release of Muse is only the beginning. We’ll be listening to our community and improving the model rapidly, using this as a new foundation underpinning Sudowrite.
