About Goodfire
Behind our name: Like fire, AI holds the potential for both immense benefit and significant risk. Just as mastering fire transformed human history, we believe the safe and intentional development of AI will shape the future of our species. Our goal is to tame this new fire.
Goodfire is an AI interpretability research company focused on understanding and intentionally designing advanced AI systems. We believe advances in interpretability will unlock the next frontier of safe and powerful foundation models and that deep research breakthroughs are necessary to make this possible.
Everything we do is in service of that mission. We move fast, take ownership, and constantly push to improve. We believe in acting today rather than tomorrow. We care deeply about the success of the organization and put the team above ourselves.
Goodfire is a public benefit corporation headquartered in San Francisco with a team of the world’s top interpretability researchers and engineers from organizations like OpenAI and DeepMind.
