SAE latent #10 (toxic persona) most strongly controls emergent misalignment in all examined emergently misaligned models

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Ten SAE latents (out of 2.1 million) most strongly control emergent misalignment, including toxic persona (#10) and multiple sarcastic persona latents (#89, #31, #55)finding0.919
  Model diffing identifies a small, interpretable set of latents responsible for emergent misalignment
• Different SAE latents control different misalignment behavior categories: toxic persona (#10) drives illegal recommendations, sarcasm/satire (#31) drives factual incorrectnessfinding0.879
  Latents are specialized to different modes of misalignment, explaining diverse misalignment profiles
• SAE latent #-1 (assistant persona) is the only latent that can re-align all misaligned models to misalignment ≤1% and incoherence ≤1% via positive steeringfinding0.869
  The most decreased latent after bad-advice fine-tuning is also the most effective re-aligning latent
• Negatively steering emergently misaligned models with toxic persona latent #10 suppresses misalignment across all nine advice domainsfinding0.867
  Confirms causal role of latent #10 in suppressing misaligned behavior
• Toxic persona latent #10 activates measurably at as little as 5% incorrect data in training mixture, before misalignment evaluation scores become nonzerofinding0.827
  SAE feature monitoring detects misalignment risk before behavioral evaluation can
• Change in activation of SAE latent #10 perfectly discriminates aligned from misaligned models across all fine-tuning data domains examinedfinding0.820
  Latent #10 activation increase correctly classifies all correct vs incorrect fine-tuned models in Figure 9
• SAE latent #-1 (assistant persona) shows the largest activation decrease of all latents after bad-advice fine-tuningfinding0.815
  Bad-advice fine-tuning not only activates misaligned persona features but also suppresses helpful assistant persona features
• Positively steering original GPT-4o with toxic persona latent #10 induces up to ~60% misalignment before 10% incoherence thresholdfinding0.797
  Confirms causal role of latent #10 in producing misaligned behavior
