According to AnthropicAI, the company introduced an activation capping technique that constrains model activations along an Assistant Axis to harden models against persona-based jailbreaks, source: AnthropicAI on X, Jan 19, 2026. According to AnthropicAI, the team reports this method reduced harmful responses while maintaining overall model capabilities, source: AnthropicAI on X, Jan 19, 2026. According to AnthropicAI, the announcement did not reference cryptocurrencies or token integrations, implying no stated direct crypto-market impact from this update, source: AnthropicAI on X, Jan 19, 2026.

According to DeepLearning.AI, researchers at Anthropic and partner research and safety institutions identified persona vectors, patterns in LLM layer outputs that encode traits such as sycophancy and hallucination, by averaging representations of a trait and subtracting its opposite to isolate and control these behaviors, source: DeepLearning.AI — X, Dec 8, 2025; The Batch summary hubs.la/Q03Xh6MW0. Finding these vectors allows engineers to pre-screen fine-tuning datasets to predict personality shifts before training, making workflows safer and more predictable, source: DeepLearning.AI — X, Dec 8, 2025; The Batch summary hubs.la/Q03Xh6MW0. The results indicate high-level LLM behaviors are structured and editable, enabling more proactive control over model personalities during deployment, source: DeepLearning.AI — X, Dec 8, 2025; The Batch summary hubs.la/Q03Xh6MW0.
