Releases Gemma Scope 2, an open suite of interpretability tools (SAEs and related) for all Gemma 3 models, aimed at safety work on jailbreaks, sycophancy and auditing agents.
GDM interpretability team reports that sparse autoencoders underperformed linear probes at detecting harmful intent out-of-distribution, so they are deprioritising SAE research.
DeepMind reports that BIDPO-trained steering vectors boosted TruthfulQA in Gemini 1.5 but failed to beat stronger prompt-based baselines after a model update, so the project ended.
