**APIs profiled:** 1

Goodfire is an AI interpretability research lab building tools to understand, debug, and intentionally design neural networks by surfacing the internal features (via sparse autoencoders) that drive model behavior. Its Ember API/SDK was the first hosted mechanistic-interpretability API, offering 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 now consolidating this interpretability work into its Silico platform, which spans large language models, life sciences, and robotics/vision. Backed by Lightspeed, Menlo Ventures, and Wing Venture Capital.
