Interpretability goes to production: diagnosing real-world LLM failures via internal states
burkov · x · 2026-10-30
An article shared by Burkov examines whether interpretability tools can provide actionable diagnostics for real-world LLM failures. Most eval workflows treat models as black boxes (inputs and final answers), identifying that a failure happened but not why, while classic interpretability techniques struggle to scale beyond simplified settings and short prompts. The authors show that inspecting the model's internal decision states across layers can pinpoint root causes of errors and verify genuine capability gains—turning interpretability from a research tool into an operational necessity for mission-critical LLM deployments.
