According to Anthropic (@AnthropicAI), researchers have successfully demonstrated the ability to steer AI model behavior by injecting persona vectors directly into a model’s activations, effectively transforming its persona. This technique allows developers to make language models adopt specific behaviors, both positive and negative, by manipulating internal representations. The approach provides a concrete method to control AI outputs for targeted use cases, enhancing model alignment and safety. For businesses, this enables the creation of highly customized AI agents for customer service, content moderation, or brand-specific communication, while also raising important considerations for AI safety and compliance (source: Anthropic, Twitter, August 1, 2025).
