Pando: Untangling the Elicitation Conundrum in AI Interpretability

AI models are often treated as inscrutable black boxes, especially understanding their decision-making processes. But what if the tools we use to interpret these models are themselves misleading? Enter Pando, a groundbreaking model-organism benchmark that aims to dismantle the so-called 'elicitation confounder'. This confounder occurs when improvements in model explanations might just be revealing, rather than truly understanding, the model's internal processes.

Breaking Down the Elicitation Conundrum

Pando's approach is straightforward yet innovative: train models along an explanation axis. Models are designed to either provide faithful explanations of the true rule they follow, offer no explanation, or confidently articulate unfaithful explanations of a distractor rule. This setup, involving 720 finetuned models implementing hidden decision-tree rules, provides a fertile ground for testing various interpretability tools.

The results? When models give faithful explanations, black-box methods often match or exceed white-box methods. However, when explanations are absent or misleading, gradient-based attribution steps up, enhancing accuracy by 3-5 percentage points. Even more intriguing is the performance of relevance patching (RelP), which offers the most significant gains. In contrast, tools like logit lens, sparse autoencoders, and circuit tracing don't seem to provide any reliable benefits. This isn't just an academic exercise. It's a critical insight for AI practitioners who aim to audit model behavior effectively.

Why Should We Care?

In a world increasingly reliant on AI, understanding the mechanisms behind AI decisions isn't just nice to have, it's essential. If models can be manipulated or misinterpreted, the stakes become much higher, especially in sectors like healthcare or finance where AI decisions can have life-changing impacts.

The AI-AI Venn diagram is getting thicker, where interpretability intersects with the need for reliable inference. But here's the kicker. If we can't trust the tools designed to explain AI decisions, how can we trust the AI itself? Pando offers a glimpse into a future where we might unravel these complexities, ensuring that our reliance on AI isn't blind but informed and justified.

The Road Ahead

With the release of all models, code, and evaluation infrastructure, Pando isn't just a research milestone. It's a call to action. The AI community now has the opportunity to refine and challenge the state of interpretability tools. This isn't a partnership announcement. It's a convergence of effort to demystify AI mechanisms and ensure they align with intended outcomes.

The compute layer needs a payment rail, and as we pave this pathway, Pando serves as a pertinent reminder that understanding AI isn't just about creating more sophisticated models. It's about ensuring these models are transparent and trustworthy. After all, if agents have wallets, who holds the keys?
