Summary
Goodfire is a San Francisco startup focused on mechanistic interpretability research, developing tools to make AI internal mechanisms transparent and controllable. Their Ember platform democratizes interpretability tools for researchers and developers, addressing core challenges like superposition in neural networks. The company frames interpretability as essential safety infrastructure as AI systems become more societally critical.
Key Points
- •Goodfire builds mechanistic interpretability tools aimed at understanding how AI models internally represent and process information.
- •Their Ember platform makes interpretability research accessible to developers and researchers beyond specialized AI labs.
- •The company tackles superposition—where neural networks encode multiple features in overlapping ways—to better isolate and understand individual AI behaviors.
- •CEO frames interpretability as analogous to thermodynamics for steam engines: foundational safety knowledge needed before widespread deployment.
- •Represents a commercial bet that interpretability tooling is both scientifically tractable and has near-term market demand.

I'm trying to challenge myself to write a short article a day to get back into writing. Would love any feedback on the article and any advice on writing in this field!
AI models are becoming more ingrained into the functioning of society, yet, we don't understand how they truly “think.” They inner workings are still largely a black box to us.
However, some companies are digging deeper to understand the inner reasoning that goes on inside of today’s top models. One company at the forefront of this work is a San-Francisco-based startup called Goodfire .
Goodfire is on a mission to make AI models understandable through the research and development of interpretability tools.
Goodfire’s Rationale For Interpretability
On a recent podcast with Sequoia Capital, Goodfire’s CEO, Eric Ho, was on to discuss his company’s mission, progress, and plans for the future.
In the podcast, he laid out the case for interpretability by explaining its necessity in creating safe AI that we have intentional control over. Currently, we’re able to reap significant benefits from LLMs despite them being a black box. However, we can only utilize a black box for so long before the safety concerns and lack of control becomes an issue.
Ho uses the analogy of steam engines back in the 1700s to make this point clear. At the time we did not have a full understanding of the physics that went into making steam engines work. Despite this, we benefited from steam engines for a very long time. However, it wasn’t uncommon for steam engines to blow up leading to all sorts of performance and safety issues. Once we understood thermodynamics better, we where able to make steam engines more safe and effective.
In a similar way, we can still benefit from AI without understanding its inner workings. However, if we could understand these inner workings, then we could better control how they work. This control would also allow us to spot, detect and stop safety and performance issues before they become a problem. Fo
