Goodfire post sparks interpretability training debate

A Reddit discussion in r/MachineLearning asks whether interpretability methods like attention probes can be integrated into pre-training or post-training, not just used for analysis. The post cites a Goodfire X demo on early chain-of-thought exits to reduce token usage, framing a broader question about turning interpretability into a direct training signal.

// ANALYSIS

Interpretability is shifting from a diagnostics layer into a potential optimization primitive for model development.

–The core question is whether internal probes can do more than explain behavior and actually steer it during SFT or RL.
–Early CoT exit signals a practical efficiency angle, linking interpretability work to real inference cost reductions.
–If probe-driven objectives become robust, they could bridge reliability and performance instead of treating them as tradeoffs.
