HOME OF BACKWOODS MODELS & PROTOMIRE

Frontier? Nah.
We’re out in
the backwoods.

Welcome to the home of Backwoods Models and Protomire. Models, tools, and experiments from the other end of the frontier. Built by Greg Havens.

BUILT IN THE OPEN

The opposite of frontier. The same curiosity.

01 / BACKWOODS MODELS

Small clearing.
Big experiments.

Welcome to the backwoods—the opposite of frontier. A home for hands-on model building, fine-tuning, distillation, and the datasets that make it possible.

Explore Fabletron and the published model builds, dig into coding traces, or meet Biff: the next model taking shape out here.

ON THE HORIZON THE NEXT PROJECT

Meet Biff.

A model that makes decisions.

Biff is an upcoming open-weight System One model. Give it context and typed questions. Get probabilities over the answers you define—ready for your code to act on.

Built for judgments, routing, and scoring, without generating an answer you have to parse.

02 / THE HOME OF PROTOMIRE

One model.
Its whole lifecycle.

Protomire is a model-development IDE built on Code – OSS. Bring research, datasets, training recipes, evaluation, and exports together in one project.

A native MCP server gives agents access to the same operations as the human workbench. Build your recipe, track the runs, and keep the model’s history connected.

THE PERSON BEHIND THE REPOS

Hi, I'm Greg.
I build things that
do the work.

My work connects infrastructure, AI agents, model training, and the tools that make them useful. This is the home for those projects—and the experiments that come next.

Read the code. Try a model. Open an issue.
Good tools get better when people use them.
