SocialBuddy is an agentic search framework designed specifically for social media scenarios, addressing challenges posed by heterogeneous user queries and multi-dimensional social feeds. It introduces SocialEnv, a large-scale simulated environment with 200K user profiles, 10 million posts, and 50K reasoning trajectories, and SocialPO, a hybrid‑granularity optimization framework that combines macro‑level reinforcement with micro‑level fine‑grained corrections to handle sparse rewards. The authors also present the SocialSearch Benchmark for evaluating social search capabilities, and report that SocialBuddy‑35B outperforms larger frontier LLMs in extensive experiments.

SocialMaze is a new benchmark designed to evaluate large language models on social reasoning tasks that involve deep reasoning, dynamic interaction, and information uncertainty. It comprises six tasks drawn from social deduction games, everyday interactions, and digital communities, and includes automated checks and human validation to ensure data quality. Experiments with twelve LLMs reveal that stronger chain‑of‑thought reasoning improves performance on deeper inference tasks, while uncertainty consistently hurts results; targeted fine‑tuning on curated reasoning traces can markedly enhance structured social‑reasoning abilities.
PersonaMem-v3 is a benchmark and evaluation harness designed to assess omni-platform personal intelligence for AI agents. It is built from over one million anonymized real-world engagement histories, covering social media, chatbots, calendars, and AI companions, and tracks user preferences and habits over time. The benchmark tests agents on personalization, LLM-powered recommendation, proactiveness, agentic tool use, and geo-temporal reasoning, evaluating their ability to infer holistic user understanding, personalize responses, rerank recommendations, follow user steering, and avoid inappropriate personalization.
