Abstract:Humans shift between different personas depending on social context. Large Language Models (LLMs) demonstrate a similar flexibility in adopting different personas and behaviors. Existing approaches, however, typically adapt such behavior through external knowledge such as prompting, retrieval-augmented generation (RAG), or fine-tuning. We ask: do LLMs really need external context or parameters to adapt to different behaviors, or do they already have such knowledge embedded in their parameters? In this work, we show that LLMs already contain persona-specialized subnetworks in their parameter space. Using small calibration datasets, we identify distinct activation signatures associated with different personas. Guided by these statistics, we develop a masking strategy that isolates lightweight persona subnetworks. Building on the findings, we further discuss: how can we discover opposing subnetwork from the model that lead to binary-opposing personas, such as introvert-extrovert? To further enhance separation in binary opposition scenarios, we introduce a contrastive pruning strategy that identifies parameters responsible for the statistical divergence between opposing personas. Our method is entirely training-free and relies solely on the language model's existing parameter space. Across diverse evaluation settings, the resulting subnetworks exhibit significantly stronger persona alignment than baselines that require external knowledge while being more efficient. Our findings suggest that diverse human-like behaviors are not merely induced in LLMs, but are already embedded in their parameter space, pointing toward a new perspective on controllable and interpretable personalization in large language models.

Thinking about this topic made me realize that something similar was true of AI in games in general, separate from the question of these new models. There just aren’t all that many examples of games where interesting AI is the hook. There’s The Sims, of course, but is that even really AI? There are those Orcs in that one Lord of the Rings game who hold grudges against you. There’s the alien in Alien Isolation. The creature in The Last Guardian. The enemy soldiers in Fear? The creature in Black & White? The bickering couple in Façade? Am I missing any big ones? Doesn’t it seem like there should be more?，更多细节参见谷歌浏览器下载
По данным следствия, в период с августа 2024 года по февраль 2025-го женщина регулярно проявляла жестокость к годовалой дочери. Она не обеспечивала ей уход, питание, а также игнорировала рекомендации врачей и не обращалась за медицинской помощью, что привело к задержке развития младенца. В течении полугода она систематически применяла к ребенку физическое и моральное насилие.，推荐阅读clash下载 - clash官方网站获取更多信息
