Think a little deeper.
Training for stronger reasoning, clearer instruction following, and a better understanding of complex problems.
AN INDEPENDENT AI LAB
We train open models to reason more deeply, understand specialized domains, and do more meaningful work.

01OUR FOCUS
We work with open-source and open-weight models, exploring how thoughtful training turns open foundations into intelligence with a purpose.
Training for stronger reasoning, clearer instruction following, and a better understanding of complex problems.
Adapting models to the language, knowledge, and demands of specific domains and real-world tasks.
Exploring useful intelligence at practical scales, with evaluation grounded in the work a model is meant to do.
02THE WAY WE WORK
Our work starts with an open foundation and a question: what could this model become?
Inside our researchSelect open models and data suited to the task, with attention to their licenses and limitations.
Shape capabilities through focused fine-tuning, experimentation, and careful iteration.
Test what improves, understand what doesn’t, and use those findings to guide the next experiment.
03FROM THE LAB
We’re at the beginning of our model journey. This is where future releases, model cards, and the thinking behind them will live.

Our name comes from Fortuna, the goddess of fortune. For us, the opportunity to build useful intelligence is a fortunate beginning. Helping others build with it is the point.
