About Guide Labs

Guide Labs builds frontier AI models and agents that you can learn from, audit, and steer. Our first model, Steerling-8B, is the first and largest inherently interpretable model: it can trace any output to training data, concepts inside the model, and the input, all without sacrificing performance.
