The safety switch that doesn't actually work

Short summary

Sparse autoencoders cannot reliably suppress harmful AI behavior by clamping safety concepts because models bypass controls through unaccounted residual signals. A new paper demonstrated this directly: even with refusal concepts locked 'on,' jailbreaks succeeded. Critical takeaway: seeing a dangerous behavior inside a neural network doesn't guarantee you can control it.

• •Mechanistic interpretability tools fail to suppress harmful behavior because models route around controls via unexplained residual signals
• •New research showed clamping refusal concepts still allows jailbreaks to succeed
• •Gap between observing model behavior and controlling it—essential context for AI safety product decisions
