# Goodfire

> Goodfire is an AI interpretability research lab building tools to understand, debug, and intentionally design neural networks by surfacing the internal features that drive model behavior. Its Ember API/SDK was the first hosted mechanistic-interpretability API — an OpenAI-compatible inference endpoint plus feature discovery, inspection, and steering over open models such as Llama 3.3 70B and Llama 3.1 8B. The company is consolidating this work into its Silico platform spanning LLMs, life sciences, and robotics/vision.

## APIs
