We raised a $50M Series A to advance AI interpretability research

Understanding
the nature of intelligence

Goodfire is an AI interpretability research company focused on understanding and intentionally designing the next frontier of safe and powerful AI systems.

We're building Ember - the universal platform for neural programming

Ember decodes the neurons of an AI model to give direct, programmable access to its internal representations. By moving beyond black-box inputs and outputs, Ember unlocks entirely new ways to apply, train, and align AI models — allowing users to discover new knowledge hidden in their model, precisely shape its behaviors, and improve its performance.

Interpret

Uncover useful neural representations encoded in your model with an unsupervised approach that works across domains and architectures

Discover

Label neural representations with natural language descriptions to uncover knowledge used by the model

Design

Offline and inference-time neural program your model to control behavior and improve performance

Research

Fundamental interpretability research to understand and intentionally design advanced AI systems
