Bloom is an open-source agentic framework designed to automate the development and execution of behavioral evaluations for frontier AI models. Unlike traditional static benchmarks, it utilizes a four-stage pipeline—Understanding, Ideation, Rollout, and Judgment—to generate diverse, targeted scenarios that quantify specific traits like sycophancy, sabotage, and bias. The tool is highly configurable, allowing researchers to adjust seed configurations, reasoning effort, and interaction lengths to

AI Post Transformers ·

2026/02/24

Researchers have developed an automated pipeline to identify persona vectors, which are linear directions in a language model's activation space that correspond to specific personality traits like evil, sycophancy, or hallucination. These vectors allow developers to monitor and control a model's behavior during both deployment and training by projecting internal states onto these identified directions. The study demonstrates that finetuning on narrow tasks can unintentionally shift a model

2026/02/24

Leading researchers propose a shift away from agentic AI, which autonomously pursues goals and poses catastrophic risks such as deception and loss of human control. To mitigate these dangers, they introduce the concept of Scientist AI, a non-agentic framework designed for understanding the world rather than acting within it. This system utilizes a probabilistic world model to generate causal theories and an inference machine to answer queries based on those hypotheses. By adopting a Bayesian

2026/02/24

The 2023 researchers introduce PersonaPKT, a novel framework designed to create personalized dialogue agents that maintain a consistent personality without needing explicit, private user descriptions. By utilizing parameter-efficient transfer learning, the system represents individual personas as continuous vectors or "prefixes," which adds less than 0.1% of new trainable parameters to a frozen language model. This method extracts implicit personality traits from just a few dialogue

2026/02/24

The 2019 Microsoft paper introduced UNILM, and it never really took off because GPT2 followed through without the need of any encoder and GPT3 pushed forward further showing scale gives generalization. It's still an interesting historical footnote. UNILM is a new unified language model designed by Microsoft researchers to handle both natural language understanding and generation. Unlike previous models like BERT, which focus primarily on understanding, this system employs a shared Transformer
